I have a HL-T5075S tv that for the last year it has been having the following problem. It turned on fine and worked all day EXCEPT once it was on and you turn it off you could not turn it back on again. All 3 lights would flash. If you unplug and wait an hour or two it would fire right back up and work all day again. I tried a new lamp at one point and it was even worse the whole tv shut off after 5 minutes with it (maybe it was a bad lamp was a ebay 38 dollar one)…after using the oem lamp a few more months it finally quit altogether and shut off while watching it and won’t come back on now. I checked the switch and it appears to be closing the circuit fine. I checked that I have voltage to the ballast and the ballast sparks and appears to be working too. So I removed the lamp today and the color wheel appears to be spinning fine. I’m not sure what to test next? Nothing comes on the screen at all (and no audio either). I do have a multi-meter. Thoughts?
