View Full Version : Tuner problems in my DP-558
Hi,
I see diagonal color interferences (see image enclosed).
http://www.coveralia.com/capture.jpg
I have cable TV with a cable decoder. I connect the antenna cable from the "cable decoder antenna out" to the "Kiss antenna in", and from the "Kiss antenna out" to the TV. Through the TV the image is perfect, through the DVD the image is bad.
If I do this the image is perfect:
From the "cable decoder SCART out" to the "Kiss SCART in", and I select SCART INPUT. Then the image is perfect, but using this, I can't made the automatic tuning...
I have read the review of this page about DP-558 and in the page 11 the photo has the same problem than me. 8O
What's the problem?
PD: sorry for my english, I'm from spain[/img]

I have the same problem. I hope that a firmware fix with fune tuning kan fix it, because this isn't acceptable.
Yes, isn't acceptable.
How it's possible that nobody in the forum talks about this problem?
Because in the DP-558 review of this page, I can see the same problem:

(Problem detail)
I have the same problem,
I talked to the guys from divxplayer last saturday, and this is the "luminance" problem.
They told me that this is fixed in the new FW.....(will be released today, they said)
i wait and wait......and wait....
I believe your antenna signal is too strong >65 dB
Try damping the signal with an add-on equipment.
A check hint could be to pull out the antenna plug half way (discover snow on the screen) If the yellow stripes disappears, buy an add-on damping equipment, or whatever it's called in english.
Good luck[/code]
I have no problems when i put the cable directly into my TV,
Only when i put the cable into the 558
sorry, but i don't know what you mean with:
Try damping the signal with an add-on equipment.
Some tuners can not handle RF signals wich are too strong usually above 62-65dB.
I'm not sure if I use the correct word, but what you could do to maybe solve the problem, is lowering the signal (damping)
You can buy equipment for that, but you can also check if it solves the problem by talking out the antenna plug half way!
(imagine the signal from the plug being radiated ˝-1 mm into the tuner instead of being conducted. That would proberply damp the signal 20dB)
I understand you......thanx
But this is not the right solution
I bought a device of 650 euro, and i will not buy any other equipment to make the quality better.....it's their problem...
I can not record good quality TV for about a month now..................this is unacceptable
Kiss have to solve this problem...........and quick !!!
I still have convidence that they do this in a short time period......if not....
I go nuts......

Well prepare to go nuts :)
:roll:
X3M!
If the tuner can not handle stong signals, you can say it's Kiss' problem, but:
1. I think there is a standard existing for what tuners must handle. (I don't know the details)
2. The tuner on Dp558 is produced by Philips.
3. If you have own antenna, turn down the gain on your amplifier
4. If you have cable complain to the antenna company.
5. It's not only the DP558 that cannot handle strong RF's. Many Televisions and VCR's has the same problem.
6. If you wan't the quick solution, by that f!"#¤% device, it cost about 10? and is actually just a potentiometer (variable resistor)
Please let me know; did it work to plull out the plug half way?
Today, Kiss reply me about this problem.
The Kiss solution is: return the DP-558 to Kiss to change by a new DP-558.
I don't know what to do...
If I return the DP-558 to Kiss... I'll be 1-2 weeks without it, and it's possible that the problem persist.
I may wait to the new firmware? return DP-558 to kiss? or return DP-558 to shop?
What do you think about this?
Kurtko!
If you are sure that your incomming RF signal is between 60-70 dB, then Kiss is proberly right.
You should return the DP-558 for exchange.
But as I told previous, you can check if damping will solve the problem, simply by pulling the antenna plug slowly. Watch the screen as you do it and see if the yellow stripes dissapears. Snow will of course appear, but that is because pulling out the antenna damps way too much.
If it helps please let me know. I've talked to other DP-558 owners (as myself) with the yellow stripe problem, and they confirmed damping the signal solved the problem
If your RF is too strong the replaced DP-558 will act exactly the same!
I returned my player to divxplayer.nl
They test it for me, and the results to kiss...
I proberly get a new player.......
Tell us if that helped you resolve the problem.
AllanD,
I have tried to pull the antenna plug slowly... and the interferences doesn't dissapear.
Hi-Jack says me that with the new firmware this problem wll be fixed.
FYI
They tested it with a beta FW (with luminance fix)
But it didn't work.....
story continues......
8O
If it's true... i'll give back mi DP558
I'm tired of waiting like a dumb
Divxplayer.nl is still testing it.... 8O
When i have more info, i'll put it in here
Guys, base yourself on true stories you can verify and not heard off here and there...
MPC HAS VERIFIED THE LUMINANCE IS FIXED!!
Release is expected by Friday or start of next week.
(unconfirmed and different sources have different dates)

Hi-Jack
The problem can be a Ground-problem. Sometimes the shield (ground) from the antenna and electrical ground are different. Try the 558 with antenna in and out to the TV, and disconnect all other scarts, RCA from the TV and the 558. Does it help?
Sorry for my poor english....
Maybe the luminance fix work in the new FW!( with the luminance problem....)
But not with this problem.....,it seems to be another problem.
B139B:
I cannot test it at the moment, cause divxplayer.nl is testing it.
Thanx
I have changed my DP-558 by a new one and the new DP-558 has the same problem :?
Is there anybody that has not this problem?
How it's possible? it depend of country? because I have tested it in 4-5 differents places with diferents configurations and the problem persist.
Sorry for my english, I'm from Spain.
Kurtko,
I'm sorry it didn't help. It very hard to say if it's a software or a hardware problem.
All I can say is, that my DP-558 (FW1.0.7 by MightyBob) picture is interference free.
Good for me, you can say! But my RF signal on cable is too low. That's why I'm more into a hardware problem.
If the tuner is not defect, (that can probably only be checked by exchanging the DP-558) I think B139B is touching another aspect, the ground loop or ground potential problem.
It might be greek to you, but due to bad hardware design that can be a problem. Normaly the tuners are made to eliminate such problems but since I haven't studied any circuit drawings from Kiss, I will not exclude the possibility.
B139B is right about disconnecting all other equipment, but the disturping voltage on the ground can in many situations also come from the antenna amplifier.
If you have the possibility to connect a table antenna (or whatever it's called in english, you probably know what I mean) that could ether proof or eliminate the exsistens of ground disturbance.
Let me hear what experiences you gain!
Chears!

Hi-Jack
Hi Hi-jack.
Could you please clarify this for us:
Is the problem with yellow/green stripes (see images in beginning of this thread) a part of the luminance fix, which will be fixed with the next FW ???
I thought it was until I recently read Kurtko and x3m's posts. They seem to believe that this problem is NOT solved with next FW? 8O
I think a lot of 558 users are getting nervous about this.
Kurtko,
I'm sorry it didn't help. It very hard to say if it's a software or a hardware problem.
All I can say is, that my DP-558 (FW1.0.7 by MightyBob) picture is interference free.
Mine is (almost) interference free, but the quality of the picture on my TV is not as good as without the DP-558 being in between, no matter if I watch TV directly or via the DP-558 or via my VCR. There is quite some noise in the TV picture, and I am 99.99% sure the noise is caused by the DP-558. When I disconnect fully my DP-558 I have a much better picture without any noise, both on TV and VCR channel.
Good for me, you can say! But my RF signal on cable is too low. That's why I'm more into a hardware problem.
If the tuner is not defect, (that can probably only be checked by exchanging the DP-558) I think B139B is touching another aspect, the ground loop or ground potential problem.
This was discussed earlier on here (only read the English discussions by me and Durandal if you can't read Dutch): http://gathering.tweakers.net/forum/list_messages/962041/2
Conclusion was that luminance (and I suspect other problems too) was not caused by ground loop problems outside the DP-558.
It might be greek to you, but due to bad hardware design that can be a problem. Normaly the tuners are made to eliminate such problems but since I haven't studied any circuit drawings from Kiss, I will not exclude the possibility.
That's interesting! Could the DP-558 itself be the cause of ground loop problems or in any other way interfere with the signal? If that is the case, and I consider it is a possibility, I really would like to beta-test the new luminance fix to see if this will also solve my noise problem besides the luminance problem. And hopefully it will also solve the problem of not getting a picture (only sound) after a cold restart (e.g. after a crash). This is for me a really frustrating problem: it sometimes takes 20-30 restarts before I get a picture again!
Hi x3m,
Some news with your DP-558 test from Divxplayer.nl??
NO, no news yet....
They are busy with the HHC-days....grrrrrrr :twisted: :evil:
OK here is some news......
It seems to be a "hardware/tuner" problem....(not luminance)
They(divxplayer.nl) send my player to kiss for investigation.....
And tommorrow I proberbly receive a new one.....
http://www.coveralia.com/capture.jpg
So, send you're player to kiss to solve this problem. If you see this on your tv-screen
Hi x3m,
I have a new DP-558 (mi 3rd DP-558) and it has the same problem...
The new firmware will fix the problem...?
I'm a bit confused here:
x3m, you said that it was a hw problem, and that players with the problem has to be send back to Kiss, right ?
But you still hope that the next FW solves the problem.
So you (and Kiss) are still not sure about this problem, or did I miss something ???
I also have this problem, and have been hoping that the new fw can fix it, but I'm not so sure anymore. *sigh*
nope,
divxplayer.nl told me that this is a hw/tuner problem,
They send it to kiss to investigate it...
Today I get a NEW player.... and let's hope this problem is gone...
Divxplayer tested it with 2 exactly the same players/fw ect..., which record exactly at the same time from the same cable.
My player has these annoying stripes, the other player has no stripes in it.
SO that's a HW problem....
Let's hope, everything is clear after today....
again sorry for my poor englisch..
Thanks a lot for clarifying, x3m.
Unfortunately that means that my players also have to go back to Kiss. *sigh*
:cry:
Now I am really confused.
Can anybody else confirm this: Is the luminance problem the same as with the green/yellow stribes or is luminance something else?
I was told by Kiss that the green/yellow stribes problem would be corrected in a FW-update.
I guess I will know later today.
Luminance is something else :-)
Luminance means some colors are to fluent and white is very bright.
And indeed, you will notice after the update tonight rather you should file
RMA or not... Let's hope not off course...
regards
Hi-Jack
The same problem with new firmware :evil: :evil: :evil:
/Agree
As expected FW upgrading didn't help. Only one thing left to do now. :(
Firmware upgrade 1.1.0 did not work out as I already expected. As there are so many people complaining about this problem, it seems either:
- a batch of bad components (3rd party?) used by KiSS
- a design fault in the DP-558
I will request a RMA for mine tomorrow.
Didn't help me either. However, the picture is better with the new fw (concerning brightness), but the stribes are still very clear.
I have contacted Kiss and asked whether I should return my 558. :-(

The colour "white" isn't that much bright as with 1.0.5. IMHO this is better now. The colour in the human faces is 99,9% the same as on the same channel from the TV-tuner.
But what exactly are you talking about with "luminance". Could you please make an example? Where can you detect that? On a blue tennis-court? On a green snooker-table? In the face of the talkshow-people?

Same problem here with firmware 1.1.0. The Moiré effect is still as bad as with the previous firmware.
I think Kiss should give us an official reaction now.
Greetings,
Freddy
Hello, all ......here an update...
I've received my 558 back from repairing...
And "ofcourse" the problem is still there........yeaahhh, jippie, yahooooo???
(even with the new firmware the problem with the stripes is still there)
I'm gonna call divxplayer tommorrow for explenation.....
Again this is not acceptable for so much money.
story continues......
YESSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
The problem is solved!!!! :D :D :D
I have a new DP-558 with "Rev Z6".
The image is perfect!!!
If you have this problem, RMA to Kiss for new DP-558. It's a hardware problem.
:')
great......
Tomorrow i will switch it for a "rev z6".
THANX MAN
I really would like to see an offical announcement from KiSS or any other official KiSS distributor stating that hardware problems may exist in specific revisions of the DP-558 and that if one is facing one of the issues mentioned here like moiré problems, noise and/or only stripes without picture after (re)start, it can be solved by swapping it for a new DP-558 revision (> z6?).
Maybe you are just lucky that your DP-558 with this specific z6 revision does not have this problem?
I'll ask Divxplayer. In my case they only want to exchange it after they perform a full test cycle which takes them approximately 6 hours and after discussion for advice with KiSS support. I am very afraid that I get the same situation as x3m, having no DP-558 for a week, and then getting it back with the same problems still remaining :(

I have a new DP-558 with "Rev Z6".Out of curiosity: How do you detect the revision #??
Watch the box it came in. In my case it was rev.06
Or watch the label on the back of your player..
btw. I have a rev 06 too...
My last DP-558 had "Rev 06" and it had the interferences problem.
The new DP-558 has "Rev Z6" and is interferences free.

Thank you, I have rev. 06 too.
Maybe Hi-Jack should start a poll - as a christmas gift from us? :lol:

[poll answer]
My player has also rev z6 and no (interference-)problems

Question to all who has this problem....
Do you have a woofer or somekind device near it ?
(or something that makes strong magnetical or electrical field?)
If yes, try to move it away, is there any difference on the screen?
just a thought....
Is it realy so that you can change a player with rev 06 for one with rev z6
and does it solve the problem with the tv tuner?

I have a woofer right next to the DP-558. I havn't had the chance to power it down though. I hope to try this when I get home today.
/winge
Mine also has rev number 06.
And I have the 'interference' problem too. (Though I'm not sure it's actually interference at all)
Anyway, I don't have any woofer or other items like that nearby.
(So I'm more for the revision number theory. Makes sense that the '06 batch' of players all have a bad component, causing stripes when using cable-tv)
I bought a new DP-558 today, hardware version 06 and I see with my eyes this unaceptable problem, I would say it's 80% sure a hardware problem. I think Hi-Jack could clarify it (due to his direct contact with kiss).
I also updated to last firmware and the same results. I can understand that lot of bugs can be solved with new versions (like mp3 doens't works very well, FF hangs kiss when press play, etc), but if this is hardware problem then there is only one solution, and from my point of view the MAIN issue with this machine.

19-11-04, 17:39
btw: have one of you reported this issue in the MPC-BugTracker ? I haven't read it there ....
Divxplayer tested my device again today, now they saw it with their own eyes...
Immediatly i got an new 558 (rev 06) from them....
Tested it at home and.......................
PERFECT finally...
If you have this problem too....
fill out the form for a NEW 558
Entered this error in MPC-BugTracker and tomorrow I will ask for new one.
I will keep you informed here what's end of this story. 8O
Regards,
Mine is also a revision 06 and I also have the problems.
Geo
As promised 2 weeks ago (long time right? :evil: ), finally I received a "new" DP-558 (without plastic in the front and firmware 1.0.3 on it, new?).
It's rev 06 on kiss and rev 06 on box.
AND....
NOW IT WORKS !!!! :bb:
Very good image FINALLY. :D
So, I also confirm this was a hardware issue and if you have same problem RMA to kiss.
Regards,
Fran
