Hello,
I have a Samsung DM32D display.
When I try to power it on, the red LED blinks 5 times and nothing happens—the unit won’t start.
Here’s what I have tried so far:- Disconnected the cable between the mainboard and the power supply → the backlight turns on.
- Disconnected the main T-CON ribbon cable → same issue as before, the LED still blinks 5 times.
- Disconnected one of the two T-CON ribbons to the panel (tested each one separately) → same issue, the LED blinks 5 times.
From these tests, I suspect the problem might be on the mainboard. Could anyone...08-24-2025, 03:47 AM -
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... -
Hi.
I'm working on a Sony KDL-49WE663 and when I first turned it on it was blinking red 6 times.
I opened the TV and saw an inductor was fallen off the power/LED driver board so I soldered it back on and tested again, TV turns on and seems fine but the inductor heats up really fast and fell off again.
Then tested the backlight LEDs they all seem fine with LED backlight tester, every LED lights up. I even measured current draw to all individual LED which was around 27 mA.
Haven't found any shorts after hours of testing.
Inductor is about 4.5 Ohms.... -
Hi all,
I have the subject TV and it will work normally sometimes but suddenly go black and give the 2 red blinks blink code. When this happens, I check the power supply board voltages and all I have is the Standby 3.3V and BL_ERR 2.2V. When it's working normally, all power supply board voltages look normal and stable. I've checked the backlights with a tester and they all test good. I've also read that the 2 red blinks is a faulty power supply board, so could it be throwing up an erroneous BL_ERR?
Any Sony experts out there that can help??...
