Question about Panasonic PT-56LCZ70 56" HDTV
MY Panasonic PT-56LCZ70 is supposed to be adjustable to a 1366x768 resolution for PC input. To get this resolution you're supposed to select PC input, then scroll to an entry allowing adjustment to WXGA (60 Hz). When I select the PC input with the remote the TV does, indeed, go to PC input, and the TV displays 1280x1024 (the scanning is wrong, I don't see all the picture, and it's stretched). The owners manual suggests that when I first get to the PC input screen, I should also be able to get to an option allowing the switch to WXGA. I can't get to the option screen allowing the switch, or any of PC input options I see shown in a screen grab pic in the owner's manual. All I get is the screen my PC is putting out, and a brief PC input notice displayed at the top of the screen that confirms it's been selected. I've tried pushing other buttons, thinking Panasonic might have an undocumented change, but no luck. How do I get to the screen allowing the change to 1366x768?

After looking at the service manual, there is an adjustment for the vertical size, but it is in the service mans menu, and this is a dangerous place to be if you do not know what you are doing. I do have the two part service manual, and if you want to attempt this, you certainly can, but I highly advise against it, as I have seen peeps mess up a TV set royally this way. It should not cost too much to repair, unless the problem is not simply an adjustment and is a part going bad. Good Luck

If you have a problem with the convergence, believe me, going into the service menu and trying to correct it will only give you large headaches, DO NOT USE THR SERVICE MENU UNLESS YOU ARE A TRAINED TECH!!!! Doing so can result in a complete and total failure of this TV set. I service menu is not for any major changes in any adjustment. It is not the cure all. If your convergence all of a suddenly shifted, it is not a service menu issue. Your problem is the convergence amp IC's. Good Luck
