Samsung HLS-6167W shuts off every few minutes. I replaced the lamp 3x and recently the lamp ballast and #2 fan. Problem continues, so should I look at the power supply board or the color wheel?

If you heard recently a high pitched sound or fan like sound it may be the color wheel--if it fails the set will detect that and shut set off.

If lamp comes on even for a few seconds it likely is good--ballast which drives lamp is possible but rare.

Try the ballast - mine was doing the same thing, I replaced the lamp - which was only 2 months old - same thing, replaced the cooling fan - same thing - Bought a new ballast for $62.00....Yeah problem solved!

Tv have alots of clicking noises too to get tv turn on?The Ballast board is having problems.The Ballast board job it to ignite the projection lamp.

Ballast Board it is what Powers Lamp on.

If all Runs are running then replace the Ballast.

2 things will cause this Lamp is defective, or Fan to lamp quits running this will shut TV OFF, if the fan quits running while Lamp is on it is design to shut Lamp Off to prevent Damage to Lamp IF Fans are ok It will be the Ballast board It is what turns Lamp on.Look on E-Bay for Ballast board if it turns out thats what you need or call Encompasss Electronics 1-800-638-3328

This is a DLP projection that has a ballast and color wheel along with a lamp. The three flashing lights on the front are a diagnostic code. The exact meaning is listed in the owner's manual under troubleshooting. I don't have the manual for your model with me at the moment, so I can't look it up. Since the unit works OK for a while, it suggests that a component is failing under heat stress. This is often the ballast. The ballast is the part that provides the power for the lamp similar to the ballast in a flourescent light. Check the manual for the code and post it here. Also, because your model uses 2 different ballast/lamp combinations, you will need to get the lamp number off of the lamp. Please post that here too.

In the meantime, check the rear area for any obstruction in the air flow. There should be a fan in the rear that needs to be clear of debris and can turn freely. With the set unplugged, try turning hte fan by hand. It should turn easily and continue on its own slowing down to a stop. If it stops suddenly, the fan may be defective and not moving enough air to keep the lamp cool.

Keep us posted.

Check that you replaced the lamp in the right way, and also that the unit is well reassembled, you may also need to reset lamp counter from menu on some model.

Hi Wayne

It is normal for the lamp's fan to start running , but should actually happen within 15 seconds of starting up. Try changing the lamp's fan and if the problem still persists then you will have to replace the Ballast ( lamp's powersupply )

Possibly a bad fan. operate the set for at least an hour to warm it up then shut it off does the noise continue for a moment? If so its probaly the fan for the lamp that is making the noise.
