Question about Toshiba TDP-T3 Multimedia Projector
Amp runs fine, replaced lamp last year, was using, went back to it and was dark tried the old lamp, but still no light. red led flashing, reset lclock, flashed green, but still did not light
It sounds like the high voltage portion of the power supply (ballast). Turn to the solder side of the P/S board and orient it so the silkscreen is legible. Check for burnt resistor R573, 2Kohm. It's center of board, 3/4" from bottom edge. If that's OK, check 3.3kohm resistors R621, 622, 625, 628, 629, and 630. They're in the top right corner. They tend to crack. Good luck.

Still looking for a schematic, i'm a tech for 44 years myself, but on unfamiliar territory don't travel without the road map. The bulb probably isn't getting high voltage, but i'm unfamiliar with the circuitry. y'all showed having the schematic. but i couldn't operate your forum page
