I replaced the projection lamp and the light flashed red 3 times after researching i found it was the projection door now the light just flashes red non stop


Hi,

There are usually several micro switches (little metal levers) inside the projection tv - most commonly by the lamp assembly and behind the lamp door.

It's possible either:

a) the lamp is not fully seated into position - ensure the lamp assembly is locked into position and that all screws have been secured, which will correctly close the micro switch.

b) the lamp door is slightly misaligned - ensure the door is aligned properly (do not force it) and all screws MUST be secured into place, which will correctly close the micro switch.

If the above items are in their correct positions, then you may need to test the 'continuity' of the switches (open & closed) using a multimeter, to determine whether you many have a faulty micro switch.


Hope this helps..

My projector blew a bulb after installation what the problem generic bulb


Hello :

Check out the Power supply to the lamp . It must not be high . . Check if the voltages are correct to the lamp's unit and it's PCB [printed circuit board]. I recommend using a service manual .

Check for manual here please :
Sharp DT-100 Multimedia Projector manual .

........................................................................


Here is how to replace a projector's bulb correctly :

1:Make sure that your power switch is off and that the power cord is unplugged from the electrical socket.
It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.


2:In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.

3:Pull out the used lamp and clean the relevant parts using micro fiber products and not paper.
Please note that in some projectors a small inside filter should also be replaced.


4:Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself.
Touching the lamp will deposit skin oil that will likely damage any new lamp during use.


5:Reassemble the access panel, repluge the cables and power up the projector.

Things You'll Need:
new projector lamp
screwdriver
micro fiber duster
Warning:
avoid touching the bare projector lamp
I hope this will help .

rate please !

Map light fuse on 2008 f 350????


The interior map lamps are powered buy the battery saver relay ( non serviceable relay ) Which is powered by Fuse #25 ( cab fuse panel ).
This is for the engine compartment and illuminated vanity lamps, as well as the map lights.

The FET ( Field-Effect Transistor ) shows the fuse #9 also on it. ( marked interior lighting ), which power the interior lamps ( door / switch ).

Could be a few things if both those fuses are OK.

1. The map / interior lamp combos are usually dual element bulbs, which means if the interior lamps ( door or dimer switch on headlamp panel ) are OK, it could still be a burn out bulb.

2. The FET is having an issue from a dead short ( blown bulb or dead short to ground ). Until the short is correct, the FET will not turn back on.

Start with checking Fuse #9 ( marked as Fuse #8 in the diagram, but that shows headlamp ), which is to the interior lamps, and drives 1 side of the FET.

'03 Mini Cooper Xenon Replacement


If it's oem xenon than it should be 2 lamps. Because they had only xenon on the low beam (d2r type), however begin with changing the high beam. That one is inexpensive, so you could check if there are no other problems (like wiring).
Just open your hood and it should be clear how to open the cover for your high beam.

It keeps shutting off. Anywhere from 2 or 3 times


Could be several things. First replace lamp.Remove lamp door and put it back on making sure tab on door presses door switch downward when closed. Can you heard spinning noise from front. Bad color wheel will cause shutdown. Look at big cap on ballast . iff swollen replace lamp, ballast and power board. Is voltage to ballast from power board below 350 volts if so replace power board. hope this helps. Most common are lamp and door switch in up position rather than downward .

Tv turns on and off intermittently


Be sure the tab on the lamp door pushes the switch downward. Has the lamp been changed. Bad lamp commonly causes this set to shut down. Also is voltage to ballast below 350 v replace power board. I have nevr heard of a computer board in this set.

Rear projection TV


Make sure you didn't hurt the little micro switch in the door cover you took off. IF that little switch isn't activated, the set won't turn on at all. Make sure you hear it " click" Or you can hold it manually with the door removed and see if set turns on then. IF it does, you have found the culprit. Good luck and Let me know... I need the ratings...GURU JAY

The 3 blinks on this model TV means you have a lamp cover error. When you install the cover look at the tab on the cover and make sure it is making contact with the micro switch inside the lamp housing.
