Hi, I had a similar problem - the screen flicked through blue, green and red sometimes with a slight ticking noise. The problem seems to be that the colour-wheel is getting stuck - the first time this happened I sent it back to optoma who gave it a clean - it has happened again since thouegh and I just took the case off (you'll be able to see the colour wheel under a black plastic flap - remove the flap) I then used a cotton bud (q-tip) and turned the colour wheel whilst lightly pressing the cotton bud against the wheel - I also gave everything a blast with a can of air. My HD72i is ceiling mounted - optoma suggested putting the hoover pipe across the vents every now and then to keep the dust down. Essentially it's dust that is stopping the movement of the colour wheel.
how to know the bulb is weak?
is the replace bulb indicator up?
more then 1000 hrs?
picture get blur?
colour line out .nothing to do with bulb
u must check the colour filter inside
loose contact or have to do recorrection by technically
Check the green signal lead - if one of the RGB leads doesn't make good contact, the picture will take on an odd tint that doesn't always look like it's missing one of those colours. For some reason, the green is always the most common one to fail.
The ghosting problem is a combination of both the lcds and driver boards in which case neither need to be truely replaced.. They use a specific voltage to transmit data to the lcds.. Each lcd is different and the driver board is programmed by the factory for the EE v.com setting. Unfortunatly with nec, they do not offer a service mode to go in and adjust the ee settings to correct the electrical convergance. So the only way to fix the problem is to replace the lcd with a newer one who wasnt worn out from long term heat.
There is a small cover plate, about 3"X6", that 'just' snaps off. You might have to use a small screw driver to pry it open. The bulb can then be pulled out. Align the new bulb and press it down into the socket. Be careful not to touch the bulb with your hands; use gloves or a lint free cloth.
