Cannot adjust convergence, screen has rainbow effect

My Panasonic PT-47WXC43G has a rainbow effect across the whole screen, and adjusting the convergence doesnt seem to help. When watching cable tv, the problem is not so noticable, but when I turn on my video games, you can clearly see all three colors, in a ghost-like effect. Is this a bad bulb, or something else?

    I own a PT-51G and blue is coming off convergence past the point that it would be adjusted with the remote's convergence in setup.



    I have adjusted this before using a procedure obtained from a Panasonic service center.



    The screens I entered showed a sequence of grids for each color and each section of the grid could be adjusted up/down & left/right for each square on the grid individually.



    Unfortunately I lost the procedure ! - Could any one out there send me the keys sequence to enter those screens. I have service manuals with me but they don't show that in there, only the list of parameters for each mode.



    Thanks, F

You probably need to change out the semiconductors. The parts are STK392-110. There are two of them, one for horizontal and one for vertical. Search it online more.

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

Hi,
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.
Thanks.

My panasonic PT-47wxc43g projection tv has developed shrinkage in the middle of the screen on both the top and bottom. The picture has an hourglass on its side appearance. The picture is now also too large...

This could be a problem in the convergence board which will cost of repair would range 400.00 or so.
You can get the convergence repair kit at the following link which contains the parts and step by step detailed instructions.

Convergence problem

The reason you can not adjust it is because there is hardware failure in the convergence board.
Visit this website and ask them for a convergence assembly for your TV. Once you replace that assembly, the convergence might still need to be adjusted manually.
Good Luck.
