You just do autotune to receive all channels. In this mode TV will tune through the entire channel band automatically, and finally will stop tuneing, and will show the first channel receved. You must be patient for these time. about two or three minutes, without disturbing is process. The tuning process follows.

Auto Tuner Setup

In Auto Tuner Setup, the TV automatically scans

t h rough all available channels, memorizing the active

ones and skipping over blank ones or channels with

weak signals. This means when you scan (using the

CH A N N E L +/- b u t t o n s ) you will receive only clear,
active channels
P ress the ME N U b u t t o n
Press Right or Left button to operate
Press Vol+ or Vol (--) to choose CABLE or AIR
Press UP or DOWN button to move to START
Press Right or Left Button to start Auto Tuner Setup

Tv will show "NOW PROGAMMING" display.
Programming will take approximately 1 to 2 minutes.
After all it will show

Some cable systems experience interference from radio frequencies on cable Channel 95. You may delete this channel from
your scan by removing the "X" next to it on the Channel Summary screen.

If you're NOT still under warranty you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace. Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again, or if it is not blown, your problem is probably in the 'X' volt regulator and you will need professional help with the repairs. good luck!

You have whats called a verticle sweep falure. This is a componet falure and not something a handy-person should attemt to repair as theres some electronic troubleshooting involved, and some very high voltages inside the set. This happens to be a nice set, and if it was mine, I would invest the 100.00 150.00 to repair this set. Good Luck
