Panasonic 47" rear projection faded pink square

I just replace my convergence chips and most of my problems were fixed. There is a faded pink square that overlays the screen except for about 4" on the left and right side. The picture is clear except for that. It is just a little anoying. Is there anything I can do?

That is a unique problem. You might make sure that your mirror and lenses are clean and that nothing has fell in the way of the tubes. There isnt anything else that could come to mind that would cause this.

My panasonic cinemavision hdtv is showing double vision. How can this be fixed.

This is likely a convergence problem and if model number indicated here is correct set would need to have both of the stk-392-110 chips replaced and the set adjusted.

Let me know if you have questions.

Colors overlap each other and looks 3d

This is symptom of bad convergence that happens due to failure of convergence output chips in tv, there are two big black chips attached with big aluminum heat sink that will be replaced to solve tv issue.
If you are not familiar with electronics stuff repair then call local tv repairman to replace above said chips to fix the problem.
Hope this will help.

Panasonic PT-47WXC43G green ONLY is bowed on bottom and top

It still convergence chip problem, check big resistors nearby these chips that would be open or devalued and causing problem, specially in green convergence area, your green tube/ gun is just fine and just not getting convergence output signal to show correct image.
I would suggest to download service manual copy of this tv for small fee from any website and fix the issue with schematics help.

Replaced convergence chips, have new problem

Did you check the 2.2 ohm 2watt resistors? As often one or two will blow when the old ICs fail. The 3 blink error is indicating a problem with the convergence circuit still.

Panasonic 47 inch Projection tv PT-53WX42F

Sounds like your convergence chips are going. Unless you are real handy with soldering iron I would suggest having a tv repair shop service it(probably cost $200-300). If you are handy then I believe the chips you need are Sanyo STK392-110. There should be 2 of them. be careful if you order them online, there are lots of chinese knock-offs out there.
