Hi , i own a china made DLP projector called PD-X770. It has the following problem.
1)Pressing the power button lights the lamp for 1 second , you can hear an instant buzz sound and then it goes of with a red light.
The spinning wheel starts while the lamp is lit for 1 sec then spins off.
1 every 50-60 trys the projector lights up normally, then a NOT very loud buzzing sound is coming from the ballastt.It is ok for 10-15 minutes then either it goes off or it freezes in black n white picture of the last frame of what i was watching
Anyone has any ideas ? Colour wheel ? ballast ? a capacitor ?
the lamp seems ok as inspected it and had about 1300 hours. picture is ok also when once in 50 shows up
Please help , i dont have any manual or smth similar for that , its an oem projector from china
Thank YOu in Advance
