Lamp replaced 1.5 years ago, now the picture goes out but comes back on every few minutes, as if it gets to hot and needs to cool down. Fan comes on.


Lamps only last for 5,000 hrs -8,000 Playing hrs
It means every hour you Play TV Lamp burns up the hours, so after 5,000hrs on most Lamp needs replacing, some Lamps dont even last this long DLPs are not like Projection you can play them 24-7 and Tubes will remain good, But Lamps are like a light bulb they all burn out after so many hours.
Best thing is to turn TV off if you are not watching it, in order to Save Hours burt on Lamp.
Mats has Lamps for $99.00 1-800-628-1118
Replace the Lamp.

Most likely a capacitor in the power supply went out. otherwise it may be a bad relay if there happens to be one.
Most reason for a tv not turning on at all is bad power supply

LAMP


Replace the lamp. In rare cases, the lamp power supply or lamp ballast may also need replacing. But, replace the lamp first, and use an original Sony lamp not a cheap aftermarket replacement. If this helps, please be sure to rate the fix! Thanks!

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

Grand Wega picture going on and off; standby light flashing, sound remains on


Is the cooling fan running properly?  I'm just guessing, but it sounds like it could be overheating and shutting off, which allows it to cool off enough to turn on and overheat all over again.
