Ya, sure sounds the same. As soon as it's plugged it it turns on, you hearing the start up sound but see no picture. Then the far right green light blinks about 17 blinks, aprox 1 min then a 3 flash hear it turn off then back on does the process over again. After a bit or a couple times of doing that all 3 lights red, green green just continually blink.
Where did you find the parts? I was looking at TVs some too but for me get one about the same size and good quality be a bit much. The DLP LED doesn't have alot that goes out so theatrically anyway we fix this stuff should really extend the life. If that is the problem and can even get it to work under 1,000. There are some pretty nice TV at a god price and be able to hang them on the wall.
