Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.It's major symptoms are clicking,electrical sounds,shuts off and on and get the lamp indicator. This is the most common failure ,what happens is that the ballast was providing lesser voltage to the old lamp the newer one takes more voltage.You will need to replace it,you can find your part on discount-merchant or partstore.com good luck and God bless!

I have a 55in Samsung Dlp the color looks good but a little dark can't see picture if the movie is dark


You might need a new bulb, the bulbs get dim as there life diminishes. Replace the bulb to get a bright picture. Do not use cheap bulbs, an OEM bulb for that tv should be $60+. . Cheap clone bulbs will work but will fail a lot sooner

I have a Samsung HLP4663wx xaa that I just replaced the color wheel to fix the buzzing noise and then had to replace the lamp after 16541 hours so definately got my moneys worth. Had to remove the jumper...


I would assume you need to replace that ballast. Usually the bulbs out live the bulb's ballast (from previous experience)...I've seen DLPS do this type of thing when the bulbs are slow to turn on due to a new ballast being needed.


Thanks and hope it helps!

When powered up picture comes on very dim then it turns off but unit fans stay on for 5 minutes then shuts down all the while the power button is flashing.


You most likely need a new light bulb. The bulb is an Osram P-VIP 180/230w. Just google it, or here is a link to it: http://www.purelandsupply.com/D1000-Bulb-Cinego-Lamp-Bulbs.html They cost about $180 new. Good luck!

PS - Be sure NOT TO TOUCH the bulb when you replace it. The oil in your finger skin will cause the lamp to fail early.

The TV shuts off as soon as you turn it on.


You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

I turn tv on...green light comes on but i get no picture or audio....then light indicator blinks red


Hello!
Lamp or ballast(if lamp has been replaced) is bad.
Explanation: green comes on: system works, waiting for light to shine into light engine: no light is coming out of lamp, system shuts down, then you see red! how to determine: pull the lamp out of the unit's compartment. Inspect lamp: bloated stem? shuttered? reflector is not shiny? Chuck it!
Lamp looks good or just been replaced: try ballast. Close lamp compartment without lamp itself. Make sure, door is shut, as well. Turn unit on and listen close to lamp compartment: good ballast will make a buzzing noise, then stop. You've got "red'! No buzzing: ballast quit. Needs major repair! Lamp must be good, for sure, to get to the last part of diagnostics. Conclusion: more, than 2000 hours of usage: replace lamp first!
Good luck,
Alex.

After 20 minutes of use picture shuts down. (Sharp XR-10X)


use canned air and blow every bit of dust out of every vent and hole. if you want to, you can remove the top (6 screws on the bottom, and the 2 top screws on the back) and blow dust out that way. i could also be a power supply problem. from excessive heat, the capacitors on the ps dry up and don't work as they should, causing shutdown.

Infocus IN72 powers up but no image, replaced the bulb but still no image...


Hi there

This is most probably a Ballast ( lamp's powersupply ) problem.

Make 100% sure that this unit is out of warranty because InFocus Projectors come out standard with a 2 year warranty.

How do I test the bulb?


Pull the bulb housing out of the side of the unit and look into the bulb, you will see that it has shattered into pieces inside. Right or left side of unit is an access door with a few screws, loosen and remove the housing holding the bulb. matelectronics carries bulbs.
