Television and Home Theater

I own a Mitsubishi WS55511  manufactured in 05/2003, with the blinking green light next to the power button. The light will blink for about 30 seconds then goes out. If I push the reset button it will start blinking again.  I do not have an owners manual.  I contacted Best Buy and they immediately said its a bulb. After reading more into the blinking light syndrome, I was reluctant to just replace it as the cost is significant. Do you have any advice or manuals available. I feel confident with the right guidance I will be able to make the TV work again.

I have a samsung rear projection tv model #hc-p4752w tv. In the convergence mode I cannot get the blue to move up and down.This is my first rear projection tv. So I am learning as I go.Plus the picture is curving inward at the top and the botttom. Can anyone please help.

My Panasonic projection tv was powering off and would not come back on.  Service man came out and stated that I need a flyback transformer.  Just fixed it for $350 after making two trips to my home as the first time he said he received the wrong part.
