I inherited this projector from a friend..so it goes.
It powers up and the "lamp" indicator comes on blinking red. I replaced the lamp, but I am still not getting lamp powered up..took it apart. basically it has three boards..a power supply board, a main board and a lamp driver board. I replaced several electrolytic caps and a power transistor that switches the power to the lamp driver board. Unit starts up, waits 20 seconds and then shifts fan speeds like the lamp has been turned on, but, no fire to the lamp! I am going to take it apart again and take pics..hard to troubleshoot hot as it has a dummy switch and the boards are stacked vertically using pins to connect them..Anyone have any experience with these?
Thanks as always
