The 3 blinks is indicating the set has shut down due to the convergence circuits. You can get the convergence repair kit for your model from www.tvrepairworld.com the kit contains the parts and the CD with repair instructions.

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.

Convergence problem not fixed after replacing STKs


I found the chips easy to replace, but time-comsuming due to the number of pins involved. I woudn't want to try it if I'd not had prior experience with soldering.

Still no response to the original question though. With 2 replaced STK392s, red is still not moving in horizontal alignment. What gives?

Projection Tv Problem


The problem you are seeing is a convergence problem. This is a common problem and is fixed either by resoldering bad connections on the convergence ICs or replacing the ICs. These are large black ICs attached to a heatsink and are marked STKxxx. Try resoldering the pins on these ICs first.

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


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.
