Overscan is there a way to adjust the overscan? i am missing text from top and bottom.

1. To enter the Service Alignment Mode (SAM), press the following key sequence on the remote control transmitter: 0-6-2-5-9-6-Status.

2. From the top level SAM menu, use the Menu Up/Down keys to highlight the Geometry sub menu.

3. Use the Menu Left/Right keys to enter the Geometry sub menu.
4. In the Geometry sub-menu, use the Menu Up/Down buttons to select VAM.
5. Using the Menu Left/Right keys, adjust VSH so that the horizontal bar is properly centered, top to bottom.

6. Using the cursor up/down keys, select VAM from the Geometry sub-menu, and use the Menu Right key to

increase the value to obtain a slight overscan.

7. If other Geometry adjustments are needed, proceed to the necessary adjustment using the Menu Up/Down

buttons.
8. Upon completion of Geometry adjustments, press the Menu button to return to the top level SAM menu.
9. To exit the Service Alignment Mode, turn the set off with the Power button on the remote control.
 

Yes, if you have the original remote and get into the adjustment menu which is hidden you can adjust width, height, and centering if you want.

I did not find the Overscan, however I changed the TV settings, hdmi to digital, and this worked. Also, I did have part of the screen missing. I called the Tech Support to setup my Mac Mini and they adjust the Overscan on the Mac System Preferences, all is fixed. Thanks for yawl help.

Steve, I am not an expert on this model but I can provide a link to the manual that may be helpful. It is a PDF format and the pages that refer to your issue are 32-36. I hope this assists you in resolving your issue. Thanks for using Fix Ya.

Please try using the zoom button on a universal remote. The button on the remote may no longer be working. Otherwise the best way is to open the set and test each capacitor and transistor with a multimeter to see which ones if any need to be replaced.

I have had what is fundamentally the same problem. I have a desktop PC that I am plugging in to my Panasonic Viera TX-32LZD80. I am using DVI connection plugged in to HDMI port.

The solution is fairly simple; use the Menu button on the TV remote to get to the Main Menu for the TV and then select Setup which should be the fourth of four options. This will get you to the Setup Menu for the TV for the current channel. Look for the Picture Overscan option, it will very probably be set to On if you have the problem of %5 or so of display being missing on all sides.

Switch Picture Overscan to Off.

This immediately should solve your problem. A note of warning on this is that I suspected this was the problem but when I first looked at the Setup Menu I could not find the Picture Overscan option.

If you are unable to find the Picture Overscan option then trying fiddling with the Aspect settings. You will probably find it set to Auto. Switch it to 16:9 and you should find the Picture Overscan option will be available from the Setup Menu.

Hope it works for you.

Also, try adjusting the settings on your cable box, not on the TV. The usually solves the problem and will then allow you to adjust the size of the picture.

it sounds like a pin-cussion correction circuit failure. A tricky circuit to troubleshoot even for an experienced tech. check servicemanuals.net for info

The overscan would certainly cause auto convergence failures since the beam the CRT's shoot out are on the corners and upper center and lower center. Being too dark can also cause issues since one of the CRT beams might not be bright enough for the sensors to register. I would first have someone adjust the vertical size if the top and bottom of the frame are somewhat cutoff.
