Television and Home Theater

i recent purchased (3days ago) 56 inch hdtv d-ila. i have no video at all except for green screen and horizontal lines that move across screen. i called jvc tech support ( i hour wait) and they said there was something wrong with t.v i contacted local authorized jvc repairmen. he stated that due to distance to my house (35 miles) and that jvc did not pay him enough to come that far he would not come(he stated that he would come if jvc reimbursed for travel and time).

Yesterday I moved my TV to the other side of my apt. After doing so I realized that my surge protector would reach the TV anymore, I desperatly wanted to watch the OC and figured I could just plug it into the wall temporarily( with an extension cord that is not a surge protector). So go figure, a few hours later I go to use the microwave and lose power. After I turned the power back on everything works, except my TV. The odd thing is that the VCR and the Sat Dish reciever both still work and they are plugged into the same place. The poor Phillips TV from like 1996 just wont turn on.

TV gurus...

I have a MediaCenter PC hooked to my Samsung 46" DLP TV via a DVI-I-to-HDMI cable, and am experiencing the following frustration...

The TV is perfectly happy accepting 800x600x60Hz resolution or even 1280x720x60Hz (or something like that -- though I don't like the way the font looks, but not a technical issue). However, what I'd really like to do is set it to set it to 1024x768, but that totally messes up the picture.

Instead of the crisp clear monitor-like image I see at 800x600, it's like two images are overlaid and offset vertically.
