I replaced the screen panel on my Sony Bravia 52w4100 and not it won't stay on. When I powered it on it green lights for a couple seconds and the backlights come on but then it clicks and shuts off, turns back on again repeating the same thing in a sequence of three, then shuts off with red light blinking six times, pausing and repeating.

Sounds like a power board reset switch gone bad. Have the power board replaced.
Good Luck Ed Pinero

SOURCE: Sony Bravia KDL 46", no picture, standby light blinks 4 times

Since the TV is still receiving power, the problem is going to be with the TV's mainboard.  After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again?  The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation.  Don't forget to provide them the error code or 4 flashes repeating.

Try leaving the TV unpugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

SOURCE: 40'' Sony Bravia goes into standby with the light blinking 9 times

I finally managed to solve this problem by unplugging everything - scarts - HDD cables - power etc and left it for an hour. When I turned it back on again the problem had sorted itself out.

sorry. Hope you still have a waranty. This is not an uncommon problem with the sony's. 99% chance that the panel went out. Could also be a balance board issue, but usually not. Call Sony for an authorized repair center

KDL-52w4100 won't turn on and LED blinks 6 times


Bus clock and/or data lines low at power on. 6 blinks of standby light denotes this. Actually, it should be a motherboard problem. Your TV need a thorough checkup before confirmation. If you wish to get more details about the blinking codes to Sony TVs, check this link.

Heard a pop , bulb blew out , replaced bulb , it worked for two days , now red light blinks three times pauses then three times and so on , tv won't turn off light won't turn off unless I unplug...


3 blinks indicates lamp door is not on or has not been reinstalled properly. This also could mean the lamp door switch has failed itself. Try removing the lamp door and putting back on, if that doesnt correct the problem then I recommend having the switch replaced.

Hi,
If Bravia tv wont stay On and shuts Off itself that means it got some internal problem, you will see red light flashing on tv front in specific blinking time that is an error code, let me know how many times that red light is blinking after three seconds long pause to diagnose problem.
Thanks.

You have a leaky capacitor in the high voltage section of your tv and it will eventually fail completely if not replaced. This is not an expensive fix $50. ballpark
