I have a Phillips, HDTV, Rear Projection TV with Chassis Number DPTV305F, it is a 2004, my friend had it and bought a new one when this stopped working so he gave it to me. When you turn it on the power light comes on, the power light blinks when you do anything with the remote, there is no picture or sound except for a continuous "chirping" noise. I attempted to get into the SDM mode to check error codes but of course didn't work with out a picture, I did try to get into the LED error mode but could not get a response that way either. I have purchased the schematics and service manual. I have checked the fuses, the capacitors (for bulging), the board for burn marks etc. Nothing obvious. I do have an electronics degree so not a complete idiot, I hope. lol Not sure being an incomplete idiot helps either. Thanks ahead of time
