It sounds like you have a bad capacitor in your power supply, thats why it keeps shutting down, and it allows ppppower to leak through and cause the line on the picture need to take it to a repairman that will replace the bad component on the power supply board. this is a common problem for that brand of TV projection, ifr you dont fix it soon it will go out and most likely take the video out with it causing a more expensive repair.

Clearly your TV is shutting down due to a problem. Based on your description, it's hard to tell if you have a vertical or convergence failure. What do you mean by "waving" line ?

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

I had the same behavior, but not as a result of power outage. The TV is driven by windows CE software and it goes haywire every now and then. Usually pulling the plug for a few seconds takes care of any problems, but not this time (as you noticed). I had unplugged my ethernet connection on the TV a few weeks ago and thought I'd hook it up again to see if there was a new software release (not likely). I went to the menu and chose "Connections" and then chose "Ethernet Setup" and then chose "Reset All". After I closed the menu the TV rebooted itself (as it said it would). After my TV rebooted I had my analog channels back. There shouldn't be any connection between these two events, but it worked for me. Hopefully it will work for you as well. Good Luck!
