PT-53WX42 53 Blue curve problem

I seem to having the same problem with my 53WX42 set..I see you were able to fix yours. Did you fix it yourself or have a repairman service the tv? If it was serviced, how much did they charge you?

    A blue curve line (about 2 ft. wide) is towards the bottom of the screen.

If you've already replaced the convergence IC's and confirmed the coolants in each tube are filled, you probably need a factory level convergence done.

The procedure is 18 pages long and requires a NTSC pattern generator to do correctly. You need a funtional remote. Personally I'd recommend finding a well-trained tech to do it for you. Takes
about 2 hours to do both 480 and 1080 modes. Anyone who tries to do it from home without equipment is asking for headaches. It's hard enough to do in our shop... (were factory service for Matsushita)

You might get away with a minor touch-up for any particular area, but going into the factory-level setup mode without knowing what you're doing is not recommended - you may find yourself replacing the EEPROM.

Good luck, Mark

Having green and pink lines on the bottom and curving in the middle of the tv. What do you suggest for the fix?


It sounds like your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

I have a 50" projetion toshbia the blue will not line up on the bottem there is also a curve i would like to know if it is worth fixing or can it be fixed and can i do this by myself and what part i could...


Hello: Seems your convergence IC's have failed. These are two large IC on the Main Powersupply board. Have both replaced as a preventive measure.
If you are good at unsoldering and soldering componet IC's then yes you can do this yourself.
The IC are STK-392-110 but use 120's instead.

Red and Green Spots


Not a fix for do-it-yourselfers, but check with Panasonic as there is a new fix. Requires tech to come and reprogram the eprom (I think).
Cheaper than a new optic board.

PT-47WX53 blue convergence PROBLEM


Sounds like you have a blue foldover in the convergence. Since tv has been worked on it could be bad ic, maybe not original, generic. I would say if you can open set and look in, look for the blue it should be marked. look for a loose connection. If you can have someone to gently tap around that blue amp and see if it moves are go away, it might be a simple loose connection and needs soldering. If not then my have to change ic again. Becareful cause set would need to be on to really check. Hope this helps.
