Unless you are a qualified TV technician, the problem is not something that you can fix. Depending on the current value of the TV, and whether or not that it's still under warranty, your choices are to take it to the nearest authorized Sony repair depot to get it fixed, or to replace it (and responsibly recycle the old electronics).

SOURCE: Problem with Sony Wega 50 in kdf-50we655 light blinks 55 times

I fixed my problem by removing the lamp and vacuuming the hell out of the hole where the lamp lives and also getting all of the dust out of the rear ventilation grids with my vacuum. I put the old lamp back in and what do you know the TV has worked perfectly ever since. My lamp was over a year old and did not show any signs of hazing on the lens that you might see on a lamp that has a ton of hours on it. I just thought I would try to put it back in before I spent a couple of hundred bucks on a new lamp.
TA DA problem fixed.

We Have a Sony KDF-50WE655, we've replaced the lamp and housing and we still have no picture or sound. Can you help?


Make sure that lamp cover is fixed back on its position securely after lamp replacement, turn On tv to check.
If still no picture or sound then check power/standby light is blinking?
If yes, count it how many times it blinks after 3 seconds long pause and let me know to diagnose possible cause of problem.
Thanks.

Sony WEGA Large Projection TV


I sounds like the projection bulb has failed. I think there is a red lamp on the front that lights up when the bulb fails however.
This sounds very similiar to what mine did when the bulb failed about 2 months ago. Once the buld fails the TV will shut itself down and keep doing that until the bulb is replaced.
