    Sanyo DP26640

    Hi, this TV when turned on the green light comes on then after a second goes back off.
    No picture, no back light, no sound. Dead

    I can't see any bad caps so I checked the voltage on the only 2 regulators it has.
    They are both 1117S then have ADJ 014 beneath the 1117s..

    Stub north, pins left to right.

    1st;
    pin 1 7.83
    pin 2 9.09
    pin 3 12.20

    2nd;
    pin 1 0.04
    pin 2 0.07
    pin 3 0.07

    Any help would be appreciated.

    Thanks.

      What DCV do you get on those pins when TV is OFF and when power switch is activated?
      "2nd;
      pin 1 0.04
      pin 2 0.07
      pin 3 0.07"
      No input = No output which can be due to the Input is fed from switched power supply section when PS-ON is applied to the power supply board.
      We also need the pictures of the whole back side of the TV so we can see how all the board are connected.

        Mystery 80s Sanyo cap - perhaps polymer?
        by cj_reha
        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...

        Sanyo DP5834 - Gray Screen
        by toddw65
        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,...

        Sanyo VHR-D4710G VCR no sound.
        by hugocarmo
        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

        Sanyo DP65E34 Backlights off after a 1-2 sec
        by fharris1977
        Hello. I have a Sanyo TV that had no backlights at first. I changed CS9 off the power supply and now the backlights will come on for a second or 2 and go right back off. I can see the image if I shine a flashlight in the screen. Anyone familiar with this particular model and problem, your help would be greatly appreciated. Thanks in advance....
