    Sony KDL-40S2000 Chassis 40WAX2 in standby mode...4 blinks

    Set was on and I heard a loud pop then went into standby mode. I was hoping it was a bad cap but upon visual inspection...to no avail. I noticed a few months prior that with no warning the video would go out but the audio would play. I could turn set off then right back on and it would play all day. I did some checking and I found F002 open. I know something is shorted, but I replaced the fuse anyway just to eliminate any curiosity I had and it blows instantly. I have my 18v source voltage at R708. Rightfully so there's no voltage at SAN1 and my next step was to lift the cable at SAN1 to take it out of the circuit because I think something is shorted on PCB2676. Any assistance would b greatly appreciated.

      I would flip the board upside down. There must be components underneath. Can we get a picture of it?

          I could not get the entire underside of the panels in one shot, maintain focus and minimize glare from flash. This is the only way I could allow you to read the print, paths and the SMD's.

              Sony KD-65XE8596 no standby light
              by brithepi2k
              Hi,

              I’ve got a Sony KD-65XE8596 here that has no standby light coming on. I’ve tested the power board with the test meter, the TV needs 3.4 for the standby but only getting 2.4. Anything that I can change/check on the board to get it working? Pictures of the board are included.

              cheers...

              Sony XR-55X90J 5 blinks
              by matwan
              Hello,

              I have problem with SONY 55X90J. After several check status is as below;
              1. Running power board as stand alone:

              TCON_12V =~ 12.6V
              EVDD V On Max 24V= 19V.

              2.              Running power board with TCON as stand alone:

              Effect as below, attched.

              3. When bottom LVDS cable is disconnected no blinks, but of course no TCON 12V and EVDD.
              "I'm almost sure it's a defective panel, but maybe someone has encountered a similar issue on their screen.

              Best regards....

              Sony XBR-75X940E intermittent 6 blinks error code
              by GoodCapDude
              Hi everyone. First post on Badcaps!

              I am trying to fix a Sony 940E from 2017 that either starts normally (and works perfectly until turned off) or goes straight to the 6 blinks error code without showing anything on the screen. It is frustrating to know that it can still work perfectly but is barely usable because of the difficulty starting it up. I am willing to try to short the BL_ERR but I would like to avoid that if possible. Does anyone have a view on this? Thanks a lot....

              Sony KD-65A1 Repair – 4 Red Blinks Error
              by AK_777
              Hi everyone!
              I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

              Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...
