Picture and sound turn on and off

OK I stand corrected, I should have done more research. I was thinking of a flat screen TV, On that type of TV the DLP you have many and I mean many things that can go wrong, I have several here (different brands) junked because when I would get one thing fixed something else would go wrong. Of all the electronic equipment I have worked on in my 33 years as an Electronics Technician those TV are the most complicated pieces of equipment I have ever worked on, They have four or five fans, a Backlight and a door switch,as you mentioned can close OK but still be bad. A ballast for the backlight that often gives trouble by over heating, and the list goes on. I am sorry, if I had it in the shop I might be able to fix it but usually the parts alone are so expensive and hard to find that you can buy a new one for about what the parts are listed for. When I sa listed that's usually what they are is listed. They do not have any in stock. Unless this TV has some kind of a sentimental value to you I would advise you to try and get a newer flat screen. I was in Goodwill the other day and they had some good looking 52" inch TV's playing and they were dirt cheap. Pawn shops often have good TV's at a good price. If you get a flat screen and ever need a board for it contact me. I have a pile of boards left over and if I have what you need I will ship it to you at no cost. Sorry I couldn't be of more help but if I can do anything else to help you just email me anytime. OK I stand corrected, I should have done more research.

Thanks again for answering. You are probably wise in your suggestion to cut my losses. It is just very frustrating that the TV is obviously 99 and 44/100% fine and has to be junked because of failure of a part that realistically has a very low cost of materials. Even if I get a tech out here for $100 service fee, will he know whether it's a sensor or switch that costs pennies or a dmd board which costs ~$600 - a core fee refund (maybe)? I'll let you know if I pursue this further. Thanks again for answering. You are probably wise in your suggestion to cut my losses.
