Sony WEGA 50 turning off every 30 seconds

I just replaced the lamp after 4 yrs on my Sony 50 WEGA. The TV was fine for the first week but now the picture cuts in/out about every 30 seconds and goes in green standby mode when it cuts out. Any ideas?

The protection circuit is cutting in and out and it is really just a high current detection system.
This is very typical of loose connections and cold solder joints which are easily diagnosed by giving the set a whack with your hand in a few strategic places.
Also check the fuse on the power supply board .

Your TV is just getting "old" and there is parts that need to be replaced. The total for the parts needed would be more than what the TV is worth.

Sony Wega 50


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.
