We are using twin LC X986 projectors and they are both displaying everything in double
vision. Focus and contrast are good.

Hi there

This sounds like a common Ballast ( lamp's power supply ) problem.

Only way to rectify this is by replacing the faulty Ballast.

I got a viewsonic pjd5111 projector used . it power on for aleaast 30 sec and shut down immediately temp light red and lamp light green . i hv tried everything .help

Check if there is a cooling fan. Is it rotating?
It is also possible that the filter is dusty and needs to be cleaned/replaced.
(all projectors have a cooling fan and a filter to prevent dust from reaching the lamp. A faulty fan or a reduced air flow may cause an overheat problem)

Plug in and green light comes on. Powers up with fan running for 30 seconds, and then power light flashes red and shuts down. Never lights up during process, but the change bulb light never comes on...

Check the lamp. If it is not blown then there is a problem in the lamp ballast circuit and the projector will need to be serviced.

I was given a Eiki,LC-XG21 projector because the person said it didn't work (the light doesn't come on.) Thinking it might be just the bulb, I thought I'd look into possibly fixing it. Before sinking $...

these are the signs of a broken bulb or a failing lamp ballast unit.

PLV-Z1 no longer powering up - Ready light is green and the Lamp light is red

I have a Sanyo XU35. Mine was starting up and showed a picture for about 15 - 30 seconds then shutting down. My lamp warning light was not coming on. When I put it in for repairs it turned out to be the lamp that needed replacing. The technician said it is not uncomman for the lamp to be gone and the lamp warning light not to come on. I got my lamp on e-bay from ping_ngo for a great price.

Won't power up

Hi, The owners manual says that if the red light is flashing, it is an indicator that it is ready to be turned on (use remote or onboard on button); flashing red & green - too high temperature inside, the unit is overheated. Check and clean the air filters; If the red light is steady, abnormal condition and you have to call for service. A copy of your manual is available at http://www.eiki.com/resources/resourcedownload.ashx?filename=/ownersmanuals/om_xb25_20_sb20.pdf Hope this be of some help. Pls post again how things turn up. good luck and kind regards.

How to reset lamp hours in Runco RS-900 if lamp will not come on? I replaced the lamp in our Runco RS 900 and I need to reset the lamp hours, but the lamp will not come on. When I turn the projector on, the green power light blinks for about 20 seconds as the unit is warming up, but then goes off and the red lamp light comes on. The fan does come on for about a minute to cool the unit back down as well. is there any way to override the lamp hours using the remote? or another way to get it reset if you can't get to the menu?
