Sony KDF-46E2000 LCD Projection TV

I have a Sony KDF-46E2000 LCD Projection TV and it will turn off after about 10 minutes and flash red light 3 times. I am able to turn TV back on after a minute and so and then in 10 minutes it will do it again. Any ideas what the problem may be? I have a similar problem with the Sony Grand WEGA KDF-46E2000, wherethe TV will power on and operate normally for 5 minutes, then go black.The green power led will flash quickly, then the picture will reappearfor a few minute and repeat the process.

The red LED never goes on, so I don;t think it's the buld..I opened andcleaned out the bulb area, but I am unsure as to the problem.

thx

This problem is little bit technically difficult, therefore i advise you to please contact any expert who can handle this or contact SONY SERVICE CENTER.
Hope you will understand my saying.
Thanks for using fixya.

3 times error shows that lamp is not installed properly or lamp cover is off / not fixed.

If you replaced TV lamp recently then check lamp cover and make sure to seat it properly.

Hi i have a sony lcd projection kdf-e50a12u and as i turn it on the green light flashes for a few minutes untill it turns to red along with the light next to it and stays red?


Sir check the lamp of your projection if already damage, if damage replace the lamp and reset also the lamp hour meter. Remove the screws to open the panel labeled "lamp" on the back of the Sony TV. Remove the screws that hold the lamp in place inside the TV. Pull the lamp out. Let me know what is your observation to the lamp so I can guide you. Good day and best regards.

Tv will shut off and red light will flash 3 times


If its Sony KDF-42WE655 TV that goes to standby and LED blinks 3 times then check Lamp Door that seems not fixed properly.
That happens when lamp replaced in TV.
If its different model number TV, let me know exact model number.

Tv is shutting down then restarting.


How old is this TV, if its more then 2 years old and have not replaced lamp yet then its problem of weak lamp. Please replace its lamp and always purchase Sony original lamp for smooth TV function.
