I've looked and searched but nothing
upon boot, the projector starts the fans but the tibes never light and I get an error code that looks like a j1
not sure if I'm reading this wrong or what but any help would be appreciated
I just had this thing working on the ground, and recently mounted it to the ceiling and this happens

after a little more digging I think my center led is burned out and the error code is b1, that and the h stop led is lit on the h convergence board
not sure where to go from here

Check for leaking capacitors and re-seat the circuit boards.
Inverting the projector can cause the boards to shift a little sometimes. Check all cable connections as well. Particularly on the H board
Tubes do not surn out like LED's do. These are CRT's they wear till you can see screen burn on them or they get cracked and loose vacuum.
When you power the projector check the back of the tubes by the beck circuit cards to see if there's an orange glow in all three tubes.
