Question about Panasonic PT-47WX51 47" Rear Projection Television
I have a Panasonic PT47WX51CE HDTV and am having problems with convergence. I have not had convergence issues with the unit until today. When I turned the TV on, the screen initially looks to have been pincushioned in, meaning the center looked relatively aligned, but the edges were stretched out with varying levels for RGB.
Further troubleshooting revealed the problem only manifests when I have a 1080i source hooked up. In this case the problem occurs both with a PS3 and my cable box (note SD channels work fine, but HD do not - similarly the PS3 works fine for 420p but not 1080i).
I bought the service manual and am following the fine convergence steps but am finding it difficult to get everything aligned (I am sure this is just time and patience on my part). One thing that I did notice was that when I enter the service menu and select my 1080i source, it has highlighted in red 1080i and 4:3 mode format.
It's my understanding that 4:3 mode doesn't really exist for 1080i. The model TV I have should be running in 16:9 with 1080i. Can anybody offer insight into some of the problems I'm having?
Get a new repair guy. Actually, the TV is working fine, it just needs
convergence aligned for the 1080i mode. You need to find someone who knows
how to do it properly and if this guy didn't know that you have to align CRT
based sets specifically for all scan modes, he is not the "repair guy" that
you want to be using.
It wld cost you around $400 to rectify this.
