I have the sony bravia KDF E50 A12U The tv went pop and wont work. On switching on the tv, the light stays green, then goes over to 3 red light flash then green. What is this and is it easily fixed?

  • This model had a problem with the lamp door warping from the heat.

Remove the door and hold it edgewise to see if warped..

There is a peg on the back of the door that engages a lever when the door is closed---if door warped set will not come on.

A simple way to confirm or deny this is to use something not metal to with the door removed ENGAGE and hold the lever forward.

DO NOT IF THE THIS SET COMES ON LOOK AT THE LIGHT OR OPERATE IT FOR PROLONGED PERIODS OF TIME.

Do not put the outer shield cover back on without the door as heat can get it also.

If set comes on with door lever engaged you need to replace the door--widely available on the internet and or from Sony---not a bad idea to buy a spare one.

let me know what happens.

Hi just relaced the bulb 6 months ago Now tv


If you do not hear anything trying to come on, no fans, or relays clicking, you probably have a Thermal Fuse that has opened. Do to the dis-assembly that is required to replace it I recommend you have a qualified Service person come out to verify the symptom and repair the set. If that is what it is I estimate 400.00 or less to repair the set.
I hope this helps
