I have a Sony Bravia KDL-40V2500 that will not power on. The indicator flashes red 3 times.
I do not hear any sound and I cannot see any backlight.
I have tried disconnecting every cable on each board one at a time to see if anything changes.
The only change is when I disconnect AC-DET cable on the Power Supply board or on the other end if I unplug the CN7009 connection on the B-Board and try to power on the TV the indicator will stay on solid green until I power off.
My friend ordered another used power supply board but it is also doing the red indicator flash 3 times... -
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... -
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... -
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.

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...
