    Sony RB2G Chassis KDL-55W815B MAIN BOARD 2 Blink Error issue resolved! Happy days :)

    For anyone interested just repaired this Sony Main board TV that had a 2 blink error code, the chassis is a RB2G which is common to quite a few different Sony models. The Ceramic 10uF 25V X7R 1206 capacitor C9114 was shorted which took the smd 2A 0603 fuse out F9101. This was powering the Buck converter TPS54332 which caused no 5V output from it.
    See the attached picture of the locations of both components. I also attach the best service manual I found for this board for anyone else in a similar position of trying to repair this main board. It's not specific to the TV model however it gives far more schematics compared to all the others I found.
    Happy New Year
    Good luck with your repairs

      Sony 85x90CK 4 red blink
      by EazyBone
      So I got this Sony and purchased it working.. got it home and it was 4 blinks red. Seller actually refunded me thankfully. Now it's massive to take apart and I know 4 blink can be the panel sometimes but not always..

      But I found a method through other ways with grounding out the bl error pin on the LD driver board. Now the tv turns on and works.

      Pin is number 27. It was either remove the resistor right next to the solder pad or solder the pad to ground. I soldered the pad.

      Now what is this going to do to the tv? Is it just going to die shortly down the road?...

      Sony KDL-52Z4500 6 Red LED Blink
      by Famo
      Hello badcaps forum.

      I have a Sony KDL-52Z4500 TV that needs a little trouble shooting. History of the TV: I bought it about 14 years ago. One year ago, I took it off the wall to move to another house. During the past year it sat in its original packaging - even with the thin film plastic bag/cover that it gets shipped in, cardboard box and all. Last week I unpacked it to mount it in the garage for my wife's gym that she has setup. Turned it on, set up a chormecast on it for her, and all was good for a week running like always (brownie points for me from the wife ).

      Sony XR-77A80J OLED 5 Blink
      by EazyBone
      Another eazybone post took on this OLED now.

      Symptoms. Hit power, white light shows briefly and then 5 blink red code. TCON issue per chart on first picture.

      I'm thinking I have a power board issue though, which is one of the options

      Now to check pin voltages from PSU to main and PSU to tcon

      Pic 2

      1 tcon on 12 -- 0v (when I hit power this goes to 3.1 stays for short time and back to zero)
      2 bl err -- 0.16
      3 evdd on --0
      4. Ac off det 3.187
      5 power on -- 3.362 BUT fluctuating randomly to 3.352
