You turn on your Samsung DLP and it takes an extra long time. Do you hear lots of clicking and maybe a few power cycles? That is your TV trying to get that pesky lamp working. Finally, the process ends and you see the 3 dreaded blinking lights. Your lamp is probably dead, burned out. You did remember to buy a replacement lamp, right?
Get That Lamp Working Again.
Sometimes your lamp may have a little something left. You may be able to stretch a little more life from a tempermental, but not completely dead lamp. There have been times, where if I remove the lamp and put it back in, it works. Other times, colder temperatures seem to cause a failure, even temporarily.
If these attemps work, DO NOT turn off your set until you get a replacement lamp or bulb. If you power down the set, you may not get the bulb working again, no matter what you do or try.
Just because the lamp looks dead doesn’t mean you have to give up on it right away. This is especially the case if you don’t have a replacement. Wait a while (especially if it lets the room warm up some) and try again. Or, pull the lamp out of the TV and put it back in.
Nothing Seems To Work.
If it’s finally given up the ghost, your lamp will need to be replaced. Unlike replacing the Samsung DLP color wheel, the lamp is easy and can be done by most anyone. The only reason to call someone is if it’s covered by warranty (and that happened to me … 3 times!)
Other Things To Try.
Correctly insert the door for the DLP bulb door. Rock the reset switch back and forth a few times. This is to make sure it moves correctly. If all else fails, add extra Balasts for testing exchange. If that doesn’t work, look at the power board that’s wired to balast.
It is amazing how much dust collects in electronic equipment. Get a vacuum fan or an air blower. You want to do this with some ventilation because dust can get everywhere, including up your nose! Clean out all the dust and debris you find inside your set. This would at least eliminate it as a cause for TV problems.
Humming noise.
If you have a “humming” noise try this. Remove the color wheel. Examne it. If you find broken pieces, that may be your problem.
Sometimes, the humming is the color wheel. Since it is running at high RPMs, if it is out of balance, you hear the resulting vibrations as humming.
DLP problems.
When there is a problem with your TV that also affects the TV menu, it’s almost guaranteed something is wrong with your DMD board. That is because the tv menu is ONLY controlled by the DMD board.
Video problems or external component issues do not show up in the menu. They are completely independent from it.
