It's a Panasonic CT-36G24C. I've had it for 5 years. I came home from work today & turned the set on. The pic was okay for a while, but when I looked back, it was a horizontal line in the middle. I could see movement. I turned the set off & turned the surge supressor off for 5-10 min. When I turned it back on, the picture was full, but shuddered for a minute, went to a thin line & then went full. It's been fine for 3 hours now. I read in the paper that the hydro company's been lowering the voltage intermittently due to the high usage. I'm hoping this could be the cause, but I'm not too optimistic. Does anyone have an idea what could cause this & about how much I can expect to pay to fix it?
