Question about Mitsubishi LVP-X80U Multimedia Projector

1 Answer

Projector will not project light (Mitsubishi LVP-X80U) LCD Proje.

Ok we first turned on the main power switch on the side. The Red power led flashed once then went solid. this is normal. Then we pressed the power button again to turn on the LCD projector. The Green led came on next to the power button but at the same time the Lamp Led came on green and was flashing about once every second, after it flashed 3 or 4 times then it started flashing every 15 seconds 3 times then the Power led came on Red and the Lamp led started to flash every second again then shut off. Red led still on. At this point the power button dose not work until you wait 60 seconds.
I looked through the manual and it sounds like it is in "Lamp stand by" the manual shows this under normal condition. every thing points to that but we can not get it out off that mode and we do not see the lamp comeing on at all. The led indicators do not show that it is a bad bulb. The manual shows that if the bulb is going bad or at the end of its life that the lamp led would be flashing red or solid red. I work at CU for the conference center we have several LCD projectors and all of them are used several times a day and 3 of them are the Mitsubishi LVP-X80U projectors and we need this one back up and running normaly. What can you do to help us out. T. Leonard

Hello toma_leonard,

First check your lamp to make sure it is seated properly in the socket.
Then check all of your interlocks (see your manual for locations), these are usually located on any hatches or doors that allow access to the lamp and or fan area. Once you check your interlocks make sure the filter and fan area is clear of dust, (some projectors have air flow sensors), and the recheck the interlocks. Once this is done , If the interlocks are not broken, or the lamp fuse blown, the projector should be working. If not it is the lamp that needs changing.

I know this may be expensive, however these lamps do go bad, as much as we wish they would not.

If you still feel it is not the lamp, have a technician check the voltage levels to the lamp and the levels of the control board circuitry.

I hope this helps,

Thank you,

Why will my mitsubishi lvp x300 projector only project a blue screen when I turn it on?

Blue is probably the default "no signal" screen. It means that the projector is getting no signal.

Mitsubishi lvp-s290u turns on and works for about an hour then turns off

Give it a good cleaning while off with canned air. Be sure to clean filter if it has one. Do not spin the fans too fast or they will lock up.

Cooling fan for lamp does not activate.

This is a very serious problem, and needs to be addressed by a service professional. If the fan does not operate it will allow the heat from the bulb to be trapped inside the projector. Often times this can result in catastrophic bulb failure (i.e possible explosion).

I was in a church where this was allowed to happen on a projector that was suspended from the ceiling and shards of glass reined down onto the chairs below and melted through the fabric.
