Question about Sony Grand WEGA KF50WE610 50" Rear Projection HDTV-Ready Television

Sony Wega 50

I have Sony Wega 50" 4 years old LCD projection TV. A year back, I have replaced the lamp first time and 2nd second time I have changed it a month back. Noticed every 10-15min, TV blanks out for 30 sec and come back. Would like to know what could be the possible problem?

    Do you get any flashing lights when the picture blanks out? And did you use an original Sony lamp as a replacement?

Usually this is a classic lamp problem, but it could also relate to a defective lamp ballast (power supply).

Now if you are replacing lamps frequently, it's likely the lamp isn't getting enough airflow to keep it cool. If you don't get the airflow issue solved it will take out the thermal safety fuse near the lamp and your set won't come on and the power light will blink red 6 times repeating itself until you unplug it. Some lamp fans are so deeply nested it takes a trained tech to get them out. Dusty environments are bad for TV's with fans in them, especially projection types.

Its possible that one of your fans has failed, and or it could be the lamp itself. Sony television will not power on if a fan is faulty. Open the back of unit and look at all fans to make sure they are running, if so then replace your lamp.

TV turns off after a few moments but come back on again after a few seconds


Remove the lamp and check to see if the connections of the lamp and the lamp driver(ballast) are ok or they look bit burned.Also the lamp should always be replaced first especially if is two years old or more.
Check to see how many times the error indicator flashes.If it flashes 5 times then the lamp driver is probably defective.
common problems are lamp and lamp driver(ballast).
let me know if you need more help.
Good luck.

Dead sony


The $1200 was for the lcd engine not the lamp. You should change the lamp. The buzz is the power supply trying to light the lamp.
