Television and Home Theater

hi i have  panasonic model number PT-50LC13 and every time i turn it on the power button on the tv flashes green for 5-10 minutes  then it flashes red then turns off, after about 8 months it started flashing like this and how do i fix it? at one point i got it to come on after 2 hours of green flashing and i always kept it on so that wouldnt happen again but we had a power outage and im back fiddling with it so can someone help me?

I have a 32" GE. when I try to turn it on, you can hear the click coming from a relay inside it and feel the static from the crt, then it goes off. This cycle repeats itself several times and then stops, but the picture never comes on and you never hear any audio. the set is less than 2 years old and I've never had any isusues before. Any suggestions would be appreciated.

I paid $150 for this TV and it looks OK minus the fact  I see a red overlap on the left and right sides of the screen.  It looks OK in the middle.  I've tried to adjust it using the tools in the menu (to no avail).  I'd like to repair myself if possible.  Could some one make a suggestion?  If it's too hard to repair myself, could someone suggest the possible problems so I won't get took by the repairman?
