Why is our Proxima Desktop Projector 8000 turning off after a period of time?


There is a THERMAL fuse that is used to prevent fires and electrical destruction of the unit. Lamps get very hot and unless the AIR flow is good, the temperature gets too hot and shuts down the system. The fan speed may be too low, the unit may need to be cooled down with an exterior fan? Try options.

Since changing the lamp a week or so ago, a constellation of small white pinpoints has proceeded to litter the screen (up to ten and counting). Cleaning the lamp has no effect.


I would think that the dead pixels are now obvious since you have increased the brightness with a new lamp. Are they multiplying like a virus?

My Samsung 46in DLP turns on but within a few minutes it truns off and the timer, lamp and red stand by/ temp lights blink. Any Ideas?


The blinking lights usually indicate that the lamp is faulty or burnt out. In this case a new lamp would be required. The lamp in your projector set should last around 3-4 years of typical use. If your lamp is at the end of it's life you may have noticed a gradual reduction in brightness over the last few months. In this case if it's still in warranty contact Samsung to arrange for a replacement lamp.
Occasionally the lamp may not come on even when it is not burnt out. You could try turning the power off for 60 seconds on the back of the set. The other possibility is that the lamp is loose. Refer to your manual on replacing the lamp and follow the instructions removing the lamp and then put it back into place. If neither of these work you will need to get a new lamp.

I have a 600w transformer - 300w per side- I ran two lengths of 12 gauge cable. 1st run is 100' with 8 20w lamps. 2nd run is 200' with 7 20w lamps. The 1st run is bright but the 2nd run is dim. I'm not...


Instead of 2 seperate wires run 1 long continuous wire & splice each light into it as you go along.There will be less resistance & the last light will be almost as bright as the first with very little difference in between.

Jvc hd7. there is "one" pixel "dead".


I don't know if its from the CCD or from your LCD Monitor. CCD dead pixels can be fix but you can't do this at home, need service center because first you gonna need Service Support Software, second you need connecting cable(QAMxxx) and (YTUxxx) Jig. Sorry

THERE is two small bright patches in the screen


the two small bright patches are actually bad pixels.there is nothing to worry about as upto 5-6 bad pixels are fine.these bad pixels do not spread generally so no reason to worry.in case the number of bad pixels on the screen increase to more than 5-6 then you can get your unit replaced by the manufacturer if in warranty.

Hp laptop 9720us screen wont brighten or dim. last week my screen went blank brought it to a shop they changed the inverter and also some cable connection . works fine just not quite as bright as before ....


You got the wrong inverter fitted - i'm sure your unit requires a sinle lamp inverter and they have cheated - putting in a generic lamp inverter and branching togeather the wires to accomodate the single plug thus reducing the available volatage for the lamps - this is why it's dim - correct part is 431391-001 Display panel power inverter - For use with single lamp display panel
