If the spots are rectangular then pixel failure is mostly the problem

The picture on my Mitsubishi ws-55315 fades away very dim and when you give a light tap on the side of the the unit the picture returns to normal


It could be oxidized contacts in the lamp housing connector. Remove the lamp housing as you would to change the lamp (follow directions in the user's manual regarding proper cool-down first!) and check the metal contact pins or blades. If they are dull or dirty, polish them with a white pencil eraser (usually the kind found on a mechanical pencil works well). Also inspect the connections to the lamp itself. If it appears they are loose or oxidized, you will need to put on a pair of clean vinyl food handler's gloves and carefully open the lamp assembly and clean them. Reinstall the lamp assembly. Do not at any time touch the bulb with bare fingers - skin oil will ruin it!

The lamp connector is the most likely spot for intermittent problems since it is high current and high temperature. It is also possible that a solder connection on the power supply board section that drives the lamp is showing the effects of thermal fatigue (cracking and oxidizing), but you would probably see much more erratic behavior, including cutout and the flashing lamp error light in that case.

It is also possible the lamp filament is on its last legs and the vibration is knocking off loose material that reduces the light output. If that is the case, there will be gray particles visible in the lamp capsule. I've seen this with a dim tabletop projector that suddenly got considerably brighter when it was picked up and turned over while it was running.

Replacing a pull chain 3-way ceiling fan light switch


OK .. the thick black and white are the power for the fan , are there also white wires on the lamp sockets ..??
The thick black wire should connect to the black wire on the switch.
The small black wires connect to the red and blue wire on the switch .. two small black wires each .. that should give you a position for 2 lights , and 4 lights, on the step switch .. but there should be white wires from the lamp sockets connected to the thick white from the fan .

please respond .

I also have whie spots on m 42" Samsung DLP tv


Actually I need you to do this... while the tv is on, go to the service menu, if the menu also has those twinkleish spots.. it's most probable to be your dmd board, if not, it's probable to be your digital video board

No setting can cause white spots on the picture, this is a fault.

By the way you can reset settings on this camera to initial state by simply removing and putting back camera batteries.
Alternatively you should have a reset command on camera settings menu.

My opinion is that this is a fault and not a settings problem.

Typically there are three kind of faults that can cause this problem:

1 - Dirty lens or water inside the lens:
The lens may be dirty inside, for example because of water condensation on internal surfaces, this will cause blurred dots or black dots. The lens must be taken apart and cleaned in this case.

2 - Defective CCD sensor.
The CCD sensor is the chip that detects the picture, if you get well defined white or colored spots on picture that is probably a defective CCD. I think this is the more likely in your case. To fix this the sensor must be replaced.

3 - Defective video chip on internal board.
This can cause any kind of problems, however it is quite unlikely.
It is an expensive repair.

Hi there

Is there any on screen prompting ?

If not , open up the lamp door at the bottom and take out the lamp. Check on the lamp's shaft for any irregularity ( i.e. vein like looking black marks or bubbles or a white spot , also check that the fillament on the inside is not broken.)

If you spot anything I listed up here , your lamp will need replacement.

If you cannot see any irregularity , check when the unit shuts down which of the LED's on the unit flashes.

It will either be your lamp or the Ballast ( lamp's powersupply ) that is faulty and will need replacement.
