Re: rear projection tv shut off and pwer button just...
Sorry, but there is not much you can do at this point. Could be a number of things. Convergance chips shorted, power supply bad. Horizontal circuit shorted. T.V's sence a problem and shut off. They hardly ever blow a fuse anymore. Problem is Magnavox sets are very poorly built and have a ton of different problems. Then you have other sets like Toshiba or Sony that only have one specific problem, and chances are that's what is wrong. I usually tell people not to waste their money on fixing Magnavox. We call them Maggot-Box. They used to be good when NAP owned them. They gave techs all kinds of help and service literature....They were great. Now a days...The absolute worst company out there!! MOST repair shops won't touch them. They just don't hold up to repairs.

power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.
How old is the tv? Sounds like the bulb. Is there any kind of lamp light indicator blinking or on? Averager life of a bulb is a few years, but could very well be shortened. Also check any surge protectors you might have. Maybe you recently had a surge and it needs to be reset. Last but not least try recycling the power on the tv. Unplug for 10 seconds then plug back in. happens a lot with cable boxes, recievers, and tv's from time to time.
