Panasonic PT-51DX80A convergence problem
You likely need to replace IC 7001, & IC 7002 convergence IC's
STK392-110, & don't buy cheapy ones, as they may not last. Also, check the low value resistors right by both IC's. Make sure you clean off the old heat sink compound, & use a generous amount on the IC's. You will likely see the large IC's on the left side looking from the rear. If you try to adjust the convergence, especially the service menu, after you fix the T.V., you will have a lot of adjusting to do. Hope this helps, Dani. |

Panasonic PT-51DX80A convergence problem
Menu, Cable, Timer, 30, Volume down (On TV), Power button (On Remote) shuld
produce a chk logo on screen. Rest is up to you, write down all the settings before changing them. Save teh data after changing it then exit with action and power button on tv.

Bought two STK's from MCM (Sanyo) for 9 bucks each (on sale) Hope they are the same quality as what was inside. Don't really want to trash this set as I'm buying a new one but I'd like to give it to someone who would like one. Still need info on how to get into the service menu and maybe how to navigate it. Thanks. |

Panasonic PT-51DX80A convergence problem
Select catv moce, select sleep timer for 30 min or more, exit menu, press
volume down on tv set, chk should appear on screen, power button on remote should bring up service menu selections.

So it's Menu then select cable, then timer for 30 minutes and tv volume down then hit the power button on remote? Sorry if I seem a little thick. |
