I picked up a Sanyo DP26647 for $20... The owner said the picture just went black.. So I bought an inverter board and have a picture .... But it still has a few problems. When I have it hooked up to my DTV HD box via HDMI the sound is kind of choppy. But when I have it hooked up to RCA vid cables the sound is fine.. Also when I have it on a channel that has a scrolling ticker (nascar) the words are blurry.. Any ideas on what could be causing these to problems?

Re: Need your thoughts on Sanyo DP26647
The second problem is likely caused by the cheap CMO/Chungwha panels Sanyo and other budget manufacturers use in their TVs. Absolutely rubbish motion performance.
The first problem might be fixed by changing the HDMI audio format in an options menu somewhere, or it might be a firmware problem, in which case it might not be fixable.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Need your thoughts on Sanyo DP26647
THanks Tom66..When I took it apart to work on it, I noticed that someone had replaced 3 caps.. They look like crappy Radio Shack ones.. Would there be any chance that those could be causing a problem.. Those caps are located right by cable that goes to the inverter board.. I plan on recapping those when I have time...Last edited by lilmonk3; 05-05-2012, 01:04 PM.Comment

Re: Need your thoughts on Sanyo DP26647
Yes radio shack caps are not the correct ones for that possition., You need low esr caps. And if the power supply had some bad filter caps, all the filter caps are probably the same crap brand that needs to be replaced.
Take a picture of the board and someone can point out what all caps to replace. Also post what brand the caps are. Might not fix your problem, but should only cost around 10 dollars to try, and I think its a very good chance it will.Fixed so far 12 lcd's , 1 plasmas, 5 monitors, 0 dlp's (plan to keep the dlps at 0). and 3 atx power supplies, and 2 motherboards.Comment

I have it all buttoned up.. But I do remember that there 3 shit ones on there, and 5 or 6 that look like they are factory.. I will pop it back open during the week when I dont have kids running loose..Comment

Re: Need your thoughts on Sanyo DP26647
Make sure to mention the series also. Like my sanyo 32" had all nippon chemicon caps, but they have many series, some of which are great, some are crap. (series is usually 2-3 letters, like KZE)Fixed so far 12 lcd's , 1 plasmas, 5 monitors, 0 dlp's (plan to keep the dlps at 0). and 3 atx power supplies, and 2 motherboards.Comment

Replaced those crappy RS caps and all the problems are fixed .. I ordered some more caps to replace the rest of the factory caps.. Thanks for everyones inputComment

The crap cap replacement also fixed the motion problem? How bizzare!Originally posted by lilmonk3 View PostPlease do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Need your thoughts on Sanyo DP26647
Yep.. The ticker motion blur is gone and also the sound distortion. I even tried reseating all the connections on the boards before I recapped, thinking maybe just loose connection.. But that didnt change anything.. So I have to think it had something to do with the caps. But who knows, I am just glad its fixed and will be taking it to the guys at the VFW after I get some more caps from digi.

I guess power to the T-con (5V or 12V) must have been low, low enough to cause problems with the DC-DC for the VON (about +15V) and/or VOFF (about -10V) voltages to the TFT. Thanks for posting your fix.Originally posted by lilmonk3 View PostLast edited by tom66; 05-06-2012, 01:33 PM.Please do not PM me with questions! Questions via PM will not be answered.

Re: Need your thoughts on Sanyo DP26647
Yeah its not that surprising that a low 5v or 12v voltage caused the von to go down, but it is surprising that nothing else stoped working first on the tv like IC's that are much more sensitive to voltage normally.Fixed so far 12 lcd's , 1 plasmas, 5 monitors, 0 dlp's (plan to keep the dlps at 0). and 3 atx power supplies, and 2 motherboards.Comment

Re: Need your thoughts on Sanyo DP26647
I have a Sanyo mod #dp26647 made July 2007
when i turn it on I hear a click inside but nothing turns on. I checked the fuse on the power supply and it tests good. don't see any bad caps the board # is 1av4u20c09700
OK after looking in to my problem more. I hear a relay click on power up , when i checked the relay is located on the video board. so now I thinking well power is getting there so not likely the power board. I looked around the board and don't see any bad caps not sure where to check next.Comment

Re: Need your thoughts on Sanyo DP26647
Since this looks like a different problem than the original thread topic it might be better to start a new thread even though it is the same TV.Originally posted by stevelock View Post
Posting a good, clear picture of the inside of the set would be helpful also, as I don't know this model and others here are probably in the same boat.
The first thing to do is check all the voltages from the power supply when you try to turn it on, what do you measure at each one?Comment
