The lamp of course would be logical to suspect---the only suggestion I have as have seen this before is some of these sets if enough dust inside will do this---seen ones that would play twenty minutes and either shut off or off and on.
Seen dead ones also where dust on the fans slows them just a little-set monitors things like that===usually we take back off and set outside with a air compressor and clean all air channels out (air gets taken in from front area and exits rear).
It at worst will rule this possible solution out and at best may resolve the issue. Seen say fifty or more sets where after cleaning with air (no matter how clean the house is it may look like a dust storm when you air it out) the issue was gone.
One even had golf ball sized white spots in picture--dust inside the two month old set's light engine.
Hi, Replace its lamp as existing lamp has been reached at end of its working hours life and need to replace to solve this issue. Please note lamp is not not broken or dead yet so you do not see lamp light on tv front. Lamp replacement procedure is easy and written in user manual. Please buy Sony original lamp for god picture in tv. Thanks.
Hi, If lamp has not been replaced in tv in last 2-3 years, then replace the lamp as symptom shows that lamp has reached to end of its working life span and causing that problem. Lamp is not dead or broke but weak so you get above said problem in tv. Thanks.
On that model look for a small yellow cap, half the size of coin, dime. LOOK very closely and you will see a small burnt spot on the cap. The TV uses about 4 of them, they are 120/110 @ 2 kv. There are located in the high voltage circuit.
This the most common, it could be flyback or HV devider.
Good Luck and Day, big irish.
