    Jvc kd-r35

    Hello guys , here I have an car radio "JVC KD-R35"
    Problem is that only one bus of buttons from front panel works ,"KEY1" bus is working. Tested all the buttons and resistors also performed continuity test and at the least voltage test on the "KEY0" and everything is okay. So it is probably faulty in the main CPU "IC301"
    Is someone have similar situation and is there any solution?
    Thank you!

    here is service manual "

      How Can I test PWM DM0365R?
      by chth96
      Hello
      I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
      So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
      I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
      I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

      test active pfc power with lamp test
      by khelane
      Hello
      I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
      Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
      Is there a way...

      Mats / mods: detected and repaired GPU fault. Cant seem to test after!
      by chronic519
      Hello.

      GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
      Found issue with a RAM block
      Replaced, green lines gone.
      Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
      Used a good card to test and same results low errors 32+.

      I am just search for some form of command to do a full test on the GPU.
      I just ran the mats command with my good GPU and passed after roughly 40 min.
      The repaired one, ran...

      Lg TCon test pins for screen test
      by alltvrepairs
      Hi,
      i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

      Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

      Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

      Appreciate your help....

      Intermittent display on Sherwood Newcastle R-965 Receiver
      by BigPete
      Hi all,

      I'm working on a Sherwood R-965 at the moment. It came in with relays clicking constantly and also going into protect mode.
      I've re-soldered a lot of dry joints and replaced quite a few capacitors and now it works, but I still have one problem I haven't solved and would like some opinions.
      The vacuum display is quite intermittent. Sometimes it won't turn on, sometimes it will turn on but the characters, numbers and letters are frozen on, regardless of which buttons are pushed. And sometimes it works flawlessly. If the display doesn't turn on initially, restarting...
