    Re: Sanyo fw65d25t no picture; good sound


    Tv is finally fixed. I found a good deal on a power supply board for it. Works just fine now. Odd thing was the power readings I took initially were good. Maybe a drop off was occurring?
    Anyway, for anyone who has run into this problem, it is a good chance on the power supply.

    Interchange parts?

    I doubt this will work but thought I would ask.
    Say I have a sanyo tv that has perfect panels but everything else is dead. But I have a westinghouse tv that has a busted screen but perfect parts. If the ribbon cables from the tcon match up, would it work?

    Well the tv finally conked out. It went off during the night after 3 weeks or so of running continuously. Haven't been able to get it back on since.
    One thing I did notice is the blink start up pattern has changed. It was one really fast blink and then eight more full blinks. Now it is ten blinks.

    Yep, tried to delete that thread and/or edit the title. I don't seem to be getting any responses and I wondered if it was the title. Now I have a new issue....

    New Problem Sanyo 65" led

    So I had a problem with no picture but sound on this tv. I checked all the power readings, cables, screws, etc. Then I replaced all at once the t-con, main board, led invertor board, and FRC. I finally got a picture. But once I turned it off, it reverted back to the same sound but no picture.
    Upon multiple power up/offs the tv picture and sound came back up. Turned it off and back to sound but no picture. Repeated multiple power on/offs and got sound and picture. No certain number of times. I have had it work in 5-6 and had it takes 30+ power on/offs but the picture will work if I keep...

    UPDATE! Working but still issues

    So I have had a long bout with this tv. Finally got the tcon, main, led driver, and frc boards all at once. Replaced everything. Still didn't work. Changed all the lvds cables and ribbon cables, still didn't work. Must have spent a good hour after changing out parts looking for something loose or mis-seated. Kept shutting off power and turning it back on with every change. Viola!! Tv comes on.
    But then I turn it off, and back to square one. Sound but no picture.
    So for the past two weeks I've been using the remote or side buttons...

    Re: Sanyo fw65d25t no picture; good sound

    So for the past 3 hrs I have been swapping parts and cables to try and see a pattern. But there isn't one. I definitely had a bad frc board because I could never get picture with the old one in. So now I'm left with power supply as the most likely culprit. Not sure what to test though.
    Maybe ill just leave the tv on all the time ��

    I'm lifting the tabs, but as someone mentioned in one of the pics I posted, the ribbon was crooked. Maybe when I "push" in the ribbons, I'm going too far?

    Alot closer!!!
    Watched the tv for hours yesterday. All good. Except when I shut it off, it wouldn't produce a picture when it came back on. So I counted red blinks. Solid red light in standby -- 1 weak quick blink after pressing power--8 full slower blinks-- then one last full but quick blink.
    Now I sat for like 10 minutes and kept power cycling-- to no avail. So I decided to tap the tcon through the case. After a couple of taps, powered on and picture came back.
    So I'm guessing its either the tcon is bad, or a cable...

    Ok picture is back and good. Weird though, it seems to be going back to the bluish/sound but no picture when I turn it off. Repeated turning off/on seems to "fix" it. Any idea what that could be?

    I was told that it just died. And no attempts had been made to fix it.
    I am reseating those cables right now. I just noticed that in the pics. However I have checked those cables before. And replaced them

    Re: Sanyo fw65d25t no picture; good sound

    Here are a few pics. The last two are what the tcon ribbons connect too.
    Tv has red standby. Pressing power makes red standby blink 6-7 times and tv only shows bluish screen, no inputs, logos, etc. I can hear sound just fine through hdmi. From behind, while powered on, the backlights are bright through the screw holes. Every board was replaced except the power board, but Buda said I could rule that out.
    So im thinking those two long strips the tcon ribbon hooks to or led strips inside. Both of which are probably beyond my repair...

    So, I have replaced the frc, led driver, main, and tcon boards. Same blue screen. Not sure what to check now.
    I assume its either the long strips the tcon connects to(which I don't see anything wrong). However unhooking one side of the ribbon cables produces a white screen. So my fear is its internal.

    Re: Sanyo fw65d25t no picture; good sound

    Ive been looking for replacement parts. The kit I was going to get is out of stock so I am trying to locate the frc, main, t-con, and led driver boards. My question is, I have seen parts that are identical except for numbers. Could these work as well?
    Example:
    I have attached two frc boards. One is for fw65d25t, the other states its for a proscan. They both have FRC-PL.MS6M36K.1 printed on them. The only difference I see is the chip numbers are not all the same.

    Thank You!...

    Since Im going to get all five boards in a kit deal, would it be wise to try one at a time or just replace the main board, frc, and tcon all at once?

    Don't have a scope. Here's my question. With what I have tested, what are the chances replacing the PS, main, tcon, frc, and invertor wont fix my problem? I'd hate to spend $100 on all that and it end up being those thin strips along the bottom edge or panel itself?
    These parts individually are more expensive than buying the kit. Obviously I'd love to just swap out the tcon or frc, but I've tried that with another tv and spent $90 to still have it not working.
    Thanks for all the input

    Still plan on getting all four boards, but if anyone could give me some things to check, that would be great.
    Is there no way to narrow down what's bad?
    I haven't been able to find a service manual for this either.
    Thanks all

    These two circled in red read 1 on meter. Doesnt seem to coincide with anything else on the board....

    Thanks for taking a stab at it.
    An online site has a "complete repair kit" which has all four boards for $99
    I may just go that route. $100 plus the $20 I initially put in for a 65" led tv wouldn't be bad
