    Sony Kv21Se42 stby light displays 4 blinks.

    I recently replaced 3 elec capacitors in the vert circuit of a Sony Kv21se42 with
    the stand by light blinking 4 times.When the tv was powered up,there were
    vertical lines on the screen and I replaced the ver IC and the television worked
    ok for 3 days and shut down again and stby light is blinking 4 times.
    Can anyone offer a solution for this problem?

      I would check the Hor Osc cct for cold solder joints, also. Hor Osc Transformer, transistor, Horiz Output Transistor, Horiz Osc IC, etc. Ther may even be a Hor Osc Crystal that may be faulty.

          Sony Bravia XBR-65x900f: No Power, No Standby-light - however 3.3v STBY is present
          by SkishyIshy
          Hey All,

          I have a Sony 65x900f that I purchased cheap because of a no-power issue.
          I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.

          I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate...

          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...

          Sony A1e 5-blinks help
          by jchon
          Hi I'm new to trying to repair TVs, but I saw a broken OLED offered for a reasonable price and thought I'd try my hand at it.

          I found the service manual, which was critical to know where to probe.
          https://www.manualslib.com/manual/20...1e-Series.html

          With it I was able to determine that my DKA board was bad, when P_ON#1/2 gets enabled REG_12 on the DKA board collapses. I'm assuming one of the downstream regulators has a short, but I couldn't work out which rail/component and replaced the DKA board entirely.

          Unfortunately the 5-blinks...

          Sony OLED XR-77A80J - Initially dead, now 4 Flashes
          by thstuff
          A) TV initially dead
          B) On a hunch of a locked up Google OS, plugged in a USB memory stick with latest FW and plugged it in. It booted into the update screen, completed the update and restarted to Home screen.
          C) Was able to perform a Reset from Settings menu and completed out of box configuration.
          D) Ran a 4K screen saver demo for about 6 hours, then turned it off for the day. Did not notice any stripes, dead zones or other artifacts in the image.
          E) Powered back on and it now runs for a few minutes before relay clicks, screen goes blank, Main Board Red Digital Optical...
