Sony KDF-E50A10 stays on for 15-20 minutes then shuts off power standby light flashes green and turns back on. Replaced bulb about 6 months ago with sony bulb. Any ideas. Thanks

The reason this happens the most is because of the lamp being weak. I have not seen anything else cause this problem. You can varify this by turning the set off and wait until it shuts down totally.
with the Sony remote, press the display button, the #5 button,
volume down button, then power button. This puts you into the the factory error code mode. If you see the lamp code with multiple errors and no other errors shown, the lamp is the problem.
Most of Sonys lamps have a aprox life of 3000 hrs. Some last longer and some shorter.
I hope this helps,

Hi There

While this set is off, does the red standby light flash any error code?


Should be some short flashes followed by one longer flash, before it starts to flash again.


Let us know what the code is.

Good Luck!
