Standby button (red) flashing on tv. tv turns on briefly(no picture) and then turns off with flashing red light re-appearing.

Watch the red light and or power light when this happens, if there is a specific number of blinks and then a pause that is a error code.

Ur power board have dead capacitors.U Know how to solders?Take the tv aparts,check these capacitors in the power board for dead capcitors like puff up or burst open.Replaced these capacitors to get power back.Or buy and replaced the whole reburbish power board at Shopjimmy.com,Ebay.com.

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

If the lamp has been replaced I would think the Lamp ballast would be most likliest followed by the color wheel and then the Digital board. You can get any part needed for your model at www.tvrepairworld.com just leave them a email they respond quickly.

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.

Unplug the TV for maybe 10 minutes, then turn it on. Sometimes these units simply need to recycle. If that doesn't work, you've likely got serious problems.

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

A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.

Thanks,
Dan

i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

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.
