    I have a 2015 KD65X9300C. The LED flashes red 4 times, and shortly after it makes a clicking sound. A short while before this happened, the TV would randomly switch off, sometimes it would reboot completely and the android logo would come on and so it would startup pretty slowly. I have opened the back of the TV, none of the capacitors appear to be bulging or deformed. I called Sony Australia and the recommended a company, so I called for a technician to come out, they basically switched on and off the TV and decided from that it requires a new screen, but I don't believe so.

    My TV is a Sony KDL 52W5100. No sound no picture. When power up, green light on, I can get the 3.3v, 12V and 15V. After 3-4 seconds, green light out, 12V and 15V died, but 3.3V stays on. Green light changed to red. Red light flashes 6 times. If I tried to rest it, red light would flash 3 times instead of 6 times. Since I still can see the 12V and 15V momentarily , is it still a power supply board problem? Please advise.

    Hi.. my tv shows bootup screen all the time after the android logo come on. Theres no picture, just the bootup screen. And the remote works except for the input and power button. I tried 2 remotes but still the input and power buttons dont work on the tv. The only way to turn on/off is to use the power button on the tv itself. What should I do?

    Hi. I have a Sony KD60x690e tv. It shows 6 red blinking lights and wont turn on. I thought this is power board issue but i do not seen any issue with the screen and the weird things is that it turns on randomly once i unplug or change the board but then i see the same issue and it does not turn on. Its works fine once its turned on. Need help

    I have a 2 year old Sony x690e with symptoms of power board failure. I dont have tools to test voltage and all, so was hoping to just be able to order a board from ebay and swap it out. Any suggestions on possibly fixing this issue? any help would be appreciated, thank you.

    I have a sony kdl-46v2500, when the tv on after about 35 to 45 min the tv will turn off and you will have 4 blink of the red light and the tv will not turn on . if i pull out the power plug wait one min and plug it back in it will turn back on . but it will only stay on or 35 to 45 min. and then shut off again . but now this is the weird part once the tv is on and i wait about 30 min and turn the tv off my self and then turn it back on it will stay on but every 30 or so i have to turn it off anf then i can turn it back on and it stay on i test that out for 4 plus hr . so what going on with it

    My 75x900e has developed very small white horizontal lines from top to bottom. TV still works and plays video, but lines are noticeable. Also gets green glitches upon powering off. Any idea on this issue?
