Picture doesn't work..Panasonic 47 inch TV PT-47WX42


A friend of mine has a Panasonic 47 inch TV PT-47WX42 that I am thinking of buying if I can get it fixed. The picture stopped working on it and he talked to a tech who told him that it probably needs a new motherboard (is that possible?). What would that cost of a new motherboard be and where could I get one to have installed?

Dood, if you really needed a new mother board for your TV the biggest problem on your hands would be finding the replacement.  The motherboard is so easy to remove it would make you laugh.  I think it has four clip bridges and four of five screws.  You seperate the clip bridges, take the screws off and maybe take a picture of the cables so you remember where to plug them in and you're done.  Like I said, take a snap shot so you dont forget where to put your cables back in.

The colors on my tv doesn't line up right. It has a 3D look and i tried to converge it. It will not let me do it. Its a panasonic HDTV PT-47WX42, PT-47WX52, PT-53WX42, PT-53WX52, PT-56WX42, PT-56WX52

set uses two of the STK-392-110 chips for convergence.

Both will have to be replaced.

I have start to finish step by step instructions for this repair based on me doing it in hundreds of these sets.

If you want the instructions, do you have a email?

Whats a panasonic pt47wx49e worth?

In this day and age of low cost LCD and Plasma TVs I would say about $300.00
You can buy a newer better TV (same size for a little more and get a warranty with it!) These are now considered stone age because of the space they take up!
