Pt-53wx53 Panasonic Projection TV Turns off

Pt-53wx53 Panasonic Projection TV Replaced convergence chips because the tv had the red/green shadows going on. Put everything back into tv, now when I turn it on it shuts off as soon as audio and picture appear. Any ideas? It also has the 3 blinker red light happening every couple seconds next to the power button. Thanks :)

OK< likely one of the new chips are bad or when soldered in you shorted pins at that time----3 blinks is short protection and you are going to find ONE of the light blue 2.2 ohm resistors is open (usually discolored in middle).

Having changed hundreds of chips in this model once in a while you get a new one that is bad---replace both again.

How did you get at them----remove the board or pull the light box?

SOURCE: Can't power up

The buzzing noise you are hearing is most likely the ballast fire, this is good. You most likely have a bad lamp which is the best case for you. I would recommend pulling the lamp out and looking at it to see if its physically shattered or not.

The instructions for pulling the lamp can be found in your owners manual. If you do not have this anymore just look on the sides or the back of the tv for a small door with a screw or 2 in it. take those screws out and the door should come off, then take the screw(s) out of the lamp and pull it out. if you see glass rolling around inside you will need a new lamp. Let me know and I will help you find a good one at a good price.

SOURCE: convergence chip

Convergence ICs cost around 15-25 each there are only two of them. I would go ahead and replace both of them because if one goes the other one will follow shortly. I would make sure that it is just the convergence IC not something else, and if its over five years old dont pay more than $500.

Replaced convergence chips in my 53" panasonic


If the chips are not fakes then check your soldering for shorts.

For all others who are having convervence failures this is a common problem. You can get all the parts from www.TvRepairKits.com

Your TV will commonly have one or more of the following symptoms:
  • Screen Looks 3D
  • Colors wont align
  • Screen may look distorted
  • No Audio or Video

You can see some examples and find a fix here...
