Television and Home Theater

I have a Panasonic TC-32LX50 32" LCD TV.  It's 1 year and 1 month old so unfortunatly just out of warranty.  When I switch it on all I see is a series of vertical color lines.  These are fixed on one side of the screen and move around on the other side.  The sound still works.  Any idea what's wrong with my TV, and if it's easy to fix?  Thanks!

I have owned this TV for approx 3 years. While watching last week the TV shut down. I have attempted to power up, but only red timer light on the front glows. I have checked the fuse, it is OK. There is no visible signs of any damage. After unplugging for several minutes and plugging back in the TV does make a sound, but does not power up. Any suggestions??? Thanks.

I have a 50" Phillips Magnavox Rear Screen Projection TV.  When it's cold, and we turn it on for the first time, the image starts small in the center and quickly grows to full screen.  Sometimes it flickers several times between sizes.

I've read this was fixed with either a $400 power supply, or OPTO COUPLER 7412 PART #483520988561 THAT COST $6.49.

Any help would be greatly appreciated.
