BenQ HT2050a No Light | Troubleshooting | Repair

BenQ HT2050a sent into my day job after the owner was unable to get it running after cleaning out an exploded lamp. The thermal breaker was unplugged(I've done it tons of times). We found our way there by troubleshooting a few things. I also go on a little detour about the DMD fan.

Hope you enjoyed it.
