Re: Sony kdl-46ex723 blinks red 3 times
ok so I downloaded this and it said 3 blink was either dc alert or audio abnormal detection, so I unplugged the speakers and still got the code? so I figured it was the dc alert, so I was testing the 3.3 volt standby and accidently touched the prong next to it and that one together now im getting a 2 blink code and I cant download the manual again so I don't know what the 2 blink code is and now I don't know what to do?Comment

Hi,
I have this tv that works for about 15 to 20 minutes and then turns off, leaving the led to blink 8 times, this via HDMI, because I can't get into the tuning menu, it says Function unavailable.
Through the manual, I was able to verify that it could be a software problem, but unfortunately the tv already has the latest software and that's why it won't let me update.
Does anyone know of a way to reinstall the software? -
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.
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... -
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.... -
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...01-08-2024, 05:56 AM
