Is is worth getting repaired?

Your lamp door switch or lamp switch (there are 2) may not be fully engaged or one may have failed. Try seating the lamp again, you may not have it fully installed.

if you have the circuit diagram of your tv,check the horizontal polarisation IC closer to the line transformer and replace it.If it doesn't work,send the question again.

It sounds like your Green CRT ( picture tube ) is shorted. That's the one in the middle. Sony had issues with there tubes in those years. Sorry for the bad news. Even if you could locate the tube, it will be a matter of time before the Red or Blue does the same.

standby button blinks no picture no sound have tried to reset and restart nothing has worked to get tv to back on

a sony should only blink up to 8 times. If its continuous without any pause that usually means No reply from the jungle (data bus is busy, shorted to ground or held
high), IK video path is defective.
Count your blinks again. let me know.

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.

i had same problem after house power switched off 3 times in same day disconnected power left overnight worked ok i will still take tv for a service .
red light was blinking 10 times

Sony has a code for those blinks indicating the problem area. Count the blonks till the pause then google Sony blink codes for the area to fix.

The picture tube on your tv is dead, you need to replace it. It probably will be worthing just purchasing a new set, because the cost of repairing it will be close to the purchase of a new one.

The unit is going in to shutdown. Sounds like you have a short in the high voltage section.
