Hi,
I have an Optoma H55 single chip DLP projector and recently started doing crazy stuff.
Sometimes it has a yellowish/red tint to everything. Blue is missing. Its not a bad connection because
it does the same on its menu items without any signal connected. Lamp its pretty bright.
Other times when I switch it on, the screen flashes sometimes and then it switches off.
Other times it works ok.
Just now, it totally stopped working... I shaked the projector in my hands and now it
stopped working. You press the power on button, the led lights up but the lamp and
fans wont. When I try to measure the resistance of the lamp I don't get any reading.
Do you have any ideas what to look for? Colour wheel, Video circuity, Power supply?
I've opened the unit but I cannot locate a colour wheel.
I cannot find any service manual either.
Thank you.
George.
