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. You can also check the board where the components are mounted and resoled any that look bad. Brief power outages may cause the TV to turn off on its own. If you are using a surge protector, try connecting the set directly to the wall outlet. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer. All can be replaced at a local electronic or hardware store and they're easy to replace If this does not correct the problem, you may need to have your TV serviced. good luck!

hello High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.

It can be just an adjustment of your screen control. There is a "sweet spot" on the control where it allows the picture to come through. This is a common problem with sets that are getting old. If there is a problem with the high voltage from the color tubes then it will shut down the video until the problem is gone and it is safe again to show the picture. This is known as going into a shutdown procedure to protect the set. A technician will be needed to fix your problem since it will require proper troubleshooting and knowledge of high voltage system and safety procedures.

Sounds like one of the tubes is shorting out causing the set to go into a shutdown status so it won't cause any major damage to the set or house.
