I have a Sanyo DP4689 and the picture turns bright and washed out. I am sure it is the TCON. I have AS15-F but the board has a AS15-HF. Can I use the AS15-F ? The way the Sanyo is put tgether You cant have the PS and Main board mounted to check the voltages

Re: AS15-HF vs AS15F
Here is the data sheet, the 'H' is for the exposed pad as noted.Never stop learning

Re: AS15-HF vs AS15F
The exposed pad is on the bottom of IC to be soldered for heat sinking? I tried reading page 11. I think it stated Datum at bottom where lead exits the body. Dont know if was shown as a W or a M in a square box. If its a electrical connection on bottom and the
AS15-HF does not have then I cant use the AS15-F. OK Thanks BudmComment

I am getting these 70 inch Samsungs daily. Dead set light comes on goes off, dark screen. Tried taping the problem lvds cable pins 13 to ? pin, used about 9 mm scotch tape. Picture comes on, no distortion lines, looks good, but 1/2 of screen is washed out. Problem seems to always be the last little strip on the bottom. Has anyone found what is actually the problem? Possibly one of three diodes there? I have a pic but it is washed out on 1/2. Anyony had success in fully restoring the picture? Thanks.07-03-2024, 05:03 PM -
Hey all
I've been working on a 1984 Sanyo 27" color TV which had a smattering of bad caps in the video switching circuit. I found this oddball little 1uF 25V cap which looks to me like an early polymer, but I can't find concrete info proving it. I know Sanyo was a big player in early polymer cap development and this is the time period where they were just getting on the market, so I'm wondering if anyone has crusty old datasheets that could help identify it and determine if my suspicions are right? It has the same epoxy end seal and font/formatting as some old stock Os-Cons I've got laying...

Hey All,
I have a Sanyo DP5834 that did have an issue with the backlights, but I disassembled the unit and repaired the LED strips by resoldering all of the connectors. Now I've reassembled it and I have backlights and sound, but a grayish screen. I can tap on the screen and see that it's on, but no picture. All voltages seem to be correct on the power board.
Based on the LCD Flat panel TV troubleshooting guide by Bud Martin, I'm thinking the T-Con has failed because I'm getting 12v both into and out of FP1 on the T-Con. Am I on the right track?
Thanks,... -
Hi again guys.
Today I have a problem with this Sanyo VCR.
I bought it online, It worked sometimes.
I recap the Power supply and it started working fine.
Image is perfect and all digital effects too.
All of a sudden it stopped outputting sound. I checked for dried solders an all boards and soldered when needed, no fix.
I have no sound on playback, on tuner, or aux in.
On symptom I noticed is when it was working fine, the HI-FI led was on when I power up the VCR, now is OFF, A-B leds are on but when I put a tape they go off.
On one of the sound processing... -
What type of caps can I use to replace these Rubycon (K) caps? Can I use a film cap? I cant find any aluminum electrolytic caps that go that low. They are .033 uf and .047 uf
