No picture or sound. standby light on front panel

this is a simple capacitor fix at your local tv guy..should be 100 to $150 max

Hi,
The Standby light LED flashing at the front panel of the TV is the self diagnostic display which can be easily identified by a service technician by counting the number of blinks.

• You can try power resetting the TV by removing the TV from the power outlet and remain unplugged for 1 minute. This will reset the internal parts of the TV.
• Disconnect all the components connected to the TV and check if the TV works normally.
• If the television is plugged into a power strip or a surge protector, remove it from the power strip or a surge protector and plug it directly into the wall outlet and check the operation.
• Try resetting the TV back to factory default. Resetting procedure using the supplied Remote is listed on the supplied manual. The resetting procedure of the TV differs with the model.

If the issue persists after the possible troubleshooting, get it serviced at a Sony authorized service center. Check if the nearest service center is offering a Home Service.
Good Luck KenSolutions

It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

When Sony TV gets problem it goes to standby as protection mode and LED start flashing.
Do you see standby light blinking?
There would be 3 seconds interval between blinks so count from pause to pause and let me know.
Thanks.

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

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.

NO PICTURE IN SCREEN

my sony red light flash.but it will not turn on just clicks

Sony
Model # KP-53HS10

Plugged in TV. Timer Standby Light just flashes continusly. No Picture and No Sound.

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.
