Question about Sony KDF-E55A20 55 in. LCD Television
Screen goes blank and comes on every 5 minutes, but green light stays on. Fan is still working .
I don't think it's the lamp I replaced that about 4 months ago and then the audio would stay on just no video now it just stops audio and video

It works!! First i took off the front panel. Just check your manual
for instructions, very easy to do. If you do not have a manual just
down load one from google.. The instruction are easy to follow. The
screw they have you loosen with a alan wrench is attached to the
plastic, so you do not have to worry about dropping it inside the tv.
Removing the lamp was simple. once out you will notice on either side
are two small mesh screens. One of mine was 80% blocked with dust, the
other side was only 30-40% covered. I used a vacuum to remove the
blockage, i did not want the dust and dirt to go inside the bulb. i
then cleaned all around the lamp. Reinstalled, and we are go to go.
The kids are happy and i am happier since my wife not be buying a new
total cost of repair $.00
time required to fix, less than 15 minutes.
Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.
hope this helps.

I had the same problem with mine. I took the lamp out, comes out from the front, and cleaned the screens on the top and bottom of the lamp. If these are dirty, mine were, they are preventing the bulb from dissipating heat. This causes the tv to shut off the lamp to cool it down. Mine works like a champ now.
