DLP TV Repair, Anyone?

How are we at repairing DLP TV's?

I have a ~10 year old Samsung DLP that won't fully power on. The lamp light blinks on the front, but the lamp does come on - albeit slowly. I took the assembly out and checked the color wheel - it makes a very slight bearing noise, but I'm pretty sure that it also spins up and down as the TV sounds normal when starting up. What else to check? Anybody ever get a lamp light error when the lamp actually lights? Oh, I bypassed the door switch and thermal switch, blew the dust out, etc.

Thanks for any tips!!

Our Mitsu DLP did this about a year after we bought it, thankfully it was still under warranty. I remember the tech saying that it was like 600 bucks to fix it, at this point honestly any fix is going to cost too much compared to what you can buy a new LED TV for. Our Mitsu finally died again about 6 months ago and we replaced it with a 4k 65" Sony and the difference is astounding.

Samsung tvs are famous for bad capacitors in the power supply boards. Usually it will sometimes not start and progressively get worse until they wont start at all. If you smell the tv when its warm it will have a beanish or farty smell, if the capacitors are bad. Easy to fix order new ones, solder in $1 $2 each.

If it powers up and spins, then it seems unlikely that it's the power supply. Easy enough to check the outputs, though.

If it needs specialized parts then it's totaled.
