Re: Internal fuse

Check that you use another power outlet,see that the power cord pins are clean,and not burnt or use a new cord,the connection at the projector makes a GOOD connection with the new cord.
You will need a multimeter to check if there is voltage at the inside of the projector cord connection.You will have to remove the internal fuse before you check the the voltage inside.If all looks good then you will have a fault on the circuit board-shorted component on power supply side or further in on the circuit(need an electronic tech for this).Hope this helps--Jay

That's a classic power supply failure. Usually, replacing the electrolytic capacitors in the power supply will be the remedy. Also, check for a blown fuse. Although, the fuse usually won't blow unless there is an internal problem.

Optoma h79 wont power up is there a fuse to replace if so where is it thanks

All electronic equipments have fuse in the power supply section.
In your projector it is inside the unit. The fuse of projectors will blows only if there is any trouble in the power supply. Just try to replace the fuse in the power supply board. It will be near the input connector. If the fuse again blews then you have to replace the power supply board. Because the components in a projector power supply is rearly available. You will not be able to access the fuse with out oppening the projector.

Dell 1409x is dead and will not power up. If the bulb goes will this cause this problem.

Do you have any LEDs indicating that the projector is getting power?
If not, it is unlikely to be the lamp which is the problem and more likely a problem with the mains supply outlet, extension cable, mains input cable, mains input fuse (all easy to check) or maybe the internal power supply (requiring professional repair).
If there are LEDs lit they will indicate a fault, for which you will either need to post the exact sequence and timings, or consult the manual.

My Toshiba TDP-S8 projector will not power up at all.

check the mains chord, also check the power in the wall socket to which the projector is connected. if all these ok then,may be its power supply side have some problem. its an smps power supply. just check its input fuse on the smps. if it fond faulty the do not replace it suddenly. check is there is any thing faulty on the smps board. because the fuse will blow off only if there is any problem in smps. check it first before inserting fuse.

Projecter went bang, is it bulb or fuse.

Hello. First, unplug the projector. Next, obtain some paper towels or newspaper and make a suitable work surface on a table. Then, open the lamp door and *being very careful here*, remove the lamp. Immediately check to see if the lamp has indeed blown--usually the bulb portion of the lamp pops into pieces but sometimes it breaks the cone shaped reflector. Next, flip the projector right-side up and shake out any broken glass fragments--hence the need for a disposable surface! Then, using a flashlight, CAREFULLY inspect the area in the lamp compartment where the lamp is aimed at to see whether the heat-absorbing glass or glass filters have been damaged by shrapnel at all. (When a lamp explodes, that much force is generated!) If any glass panels are cracked or pock-marked at all, the projector MUST BE REPAIRED before use. These glass panels can, of themselves, violently shatter due to the extreme heat from the lamp.
If no damage in the compartment has occurred, gently blow out any tiny glass fragments with canned air. Put in a spare lamp and see if the projector will power up--chances are it won't. There is an internal fuse normally located very near the power plug socket. It is usually a Buss glass fuse, 5-7 amps rated, but if you haven't worked on projectors before, I wouldn't suggest removing the top cover to get at it...send the unit off to be repaired...When a lamp blows like that, a lot of times it takes out the power supply section and/or the circuit that powers the lamp (ballast). If glass panels are damaged, the "optical engine" (internal framework that houses all the mirrors, lenses, and filters) must be replaced--that is very expensive--some companies are able to fix the optics without replacing the whole engine. Hope I helped you.---Rick

Hi there

The internal fuse will be located on the Main Powersupply Board ( the one that takes in the AC socket )

Check air flow

You need to clean the filters. When the filters collect alot of dust on them, they block the airflow to the internal parts of the projector and can cause the bulb to blow due to the temperature getting to hot.
