Question about 3M MP 8765 Multimedia Projector

1 Answer

I have recently bought a second hand 3M projector, and when turned on the screen shows half Blue (i think) and half Red and when used via the laptop the red shows through on the right hand side, can anyone tell me the problem with this? The lamp has only 648 hours on it.

First reset the settings to factory default. you may have to realign the lcd panels and make sure the panel ribbon cables are properly seated. otherwise, you have a main board issue.

Black dots projected on my 3m scp716 projector


Actually, this is a known issue with this specific model as 3M has acknowledged. We bought 4 of these and 3 have had to be replaced in 3 years because of this exact issue. It requires the mainboard to be replaced and it is almost as expensive to do this as to buy a new unit. 3M has been know help to us on this even through we bought the entire setup (Projector, Arm, Smartboard) and spent over $15000.

Try to restart your laptop and projector if still the problem still occurs try it again if the problem is still there maybe you have to ask for a technician for him to see and use it actually for him to identify the real problem..I hope it will help

reset the settings to factory default through the menu. swap out the cable. depending on your laptop, press function-f4 or function-f7. if still nothing, you may have a main board issue.

Projector lamp shows blue on white screen


the red is cutting out. white=blue+green+red. without red, you get blu+green, or cyan. if this was an lcd projector, i'd say it's a burnt light filter, the red lcd, or the lcd has come unplugged. but since this is a dlp projector, you have either a dmd board issue or a main board issue. either way, it'll be pricey.

3m projector mp 8020


hey,

i think you problem is that the s-vhs output on the labtop is not enabled.

My old labtop needed restart with the projector on, and also had a switch to set in the bios.

So take a look in you manual for the labtop.

Have you tryed the projector on a dvd player or something like that, just to bee sure the projector works fine?

best regards michael

Hi Sue, On your first concern, a possible reason for the 'Sync is out of range' is because your laptop's resolution is just too high for the projector to handle. You may have to manually lower down your screen resolution (right click on a clear area of your desktop, click on properties, settings tab, move bar of screen resolution towards the left). Try different settings that will give you best performance without the projector rejecting the input signal. Am not sure about your second concern though, offhand your description sounds like video noise. You may have to check that your connectors are firmly plugged in. A longshot is to remove any possible source of interference like wireless phones including your mobile, WiFi AP and the likes. Perhaps you give the first suggestion a try and see if the purple dots disappear when you have the projector running ok. Further you may have to reset your projector if it's got one. Normally it's a small button clearly marked RESET somewhere at the rear of the unit. Hope this works out for you. Pls comment/post back should you need further information. Good luck and kind regards.
