I have a Sony KDF-E55A20 LCD TV. It will play for 30 seconds then the TV goes black, and the projection lamp goes off, losing picture and sound. In 30 more seconds the TV will go back on, picture and sound, with the projection lamp going back on. This process goes over and over, 30 seconds on, 30 seconds off, and so on and so on. Is my problem the projection lamp or something making the projection lamp go off ?  The lamp indicator never flashes.

I also have a Sony KF-50WE610.  After warming up the screen will go partially or fully green,blurring TV images, back to normal and then on and off green. I have replaced the projection lamp, but this problem still persists.

Any ideas ?

Sounst like you got a lamp or a bad ballast board.. maybe a thermal fuse problem on the a20 the we610, I had one.. your optic block is going bad.. not much to do with that one, it is an expensive repair for that old of a TV set.

So was this problem ever solved?  I have exactly the same issue with mine.

 

The set turns on normally, green light flashes while warming up then quickly turns solid and the tv turns on with picture and sound.  Then in 30 seconds, the tv picture and sound goes off.  Then in 30 seconds it comes back on again.  The green LED never changes, it is solid all the time.

 

I can raise the volume and change the channel during the 30 seconds the tv is out.

 

I have not replaced the lamp as I don't think that is the problem.

 

Is there a resolution to this?
