Question about Sony KDF-E55A20 55 in. LCD Television
After about 45 mins of watching, tv goes black, no audio. Wait and it will come and repeat cycle. Shutting off TV and turning it back on will also temporarily solve problem. Any suggestions
I pulled the lamp, and blew the dust off of the top. TV is back to working great!

One commenter said they heard a buzz. This is the lamp ballast trying to ionize the gas in the lamp. Kind of like a spark plug arc. Very good observation, as it's hard to detect! It will do this buzz sound until either the lamp ionizes or a few unsuccessful attempts, then it will set a fault code. Normally the ballast monitors the lamp current constantly and if it gets out of spec it will do sort of a mini reset, trying to recycle to lamp voltage.
You may not have noticed the picture getting darker since it happens so subtly over time.
This type of cycling is related to a weak lamp. Change it, give all ventillation openings a good vacuuming and you should be good again.

In sets that I've seen with a bad lamp, the pic will go away and the green light will flash. However, given the age of your unit and the fact that you haven't replaced the lamp yet, that would be my suggestion. Replace the lamp with an original Sony lamp (not an aftermarket replacement, they are known to have issues). Please let me know if this takes care of your problem and be sure to rate my response. Thanks!
