My NEC just went on the blink. Powers up for a second, clicks and goes to stand-by. After repeated tries to turn it on, I was able to get it to go to component mode but it repeated itself after that. It may be a power supply issue but I'm hoping someone out there is familiar with this problem and can provide me with directions in fixing it. The screen is fine and no other problems. Would like to salvage this. Is it cheap enough to repair?
