Red light and 2 green lights on front panel on.


This is an error code it means the TV is in protection mode. Which means it has detected a problem and is preventing power up so not to cause further damage. Error codes are generally 2 numbers 1 seq of flashes a pause and a second sequence of flashes. Most common problems for LCD are Video logic / Main input board or the power supply. For more info and possible solutions post your make and model.

For parts and info check.

Flashing red center light


With most flat panel TVs, the TV turn itself OFF when it has a fail electronic part and the red light starts flashing. They call this "Protection Mode". The flashing red light should be a error trouble code.
But, it's weird that everything is working and the red light is flashing. Since you just recently bought the TV, I would get it check out while it's still under warranty. Better safe, than sorry.

Picture and sound gone


your fuses may have blown off.

open the back panel and check all the fuses. There are a bunch of fuses in there, my tv has 5 altogether.

I hope this is the problem.

Sony tv repair


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.
