I have a Samsung hlp5063w dlp tv. 1- loud buzzing noise coming from the left side of the set (looking from the front). When I tap it the noise tends to go away and come back. So I'm thinking it's the cooling fan for the lamp which I just replaced. Would the color wheel act like that when I'm tapping the side of the tv? The picture is beautiful and there are no problems there. 2- If its the cooling fan, how do I replace it?

It is much more likely considering all these the wheel fails to be your issue.The problem is often described as a fan like or high pitched sound which since the motor on the wheel turns at over 12,000 rpm is likely to be the cause.Hin ... Samsung Projection Televisions

SD Tech: Looks like your are the source for all things Samsung...I have a Samsung HL-R4226W that all of sudden started making that loud vibration/humming noise, and the picture started flashing pale, off color images of the show mostly in black and white. I shut it off before anything popped or stopped. Is this likely the color wheel? Any way to diagnose this for certain before I buy the part? Thanks in advance for the help - much appreciated.

It is definitely the color wheel. The flashing images and the wird colors confirm it. Replacing the color wheel should resolve the problem. As for the loud whirring noise, its due to wear and tear in the motor that spins the wheel. ... Flat Panel Televisions

When switched on, the power light flashes on and off on the front of the TV but no picture. We have the back part of the panel off and there are no puffed capacitors.

I have access to a multi-meter and have the checked the output of some of the connectors. Anything to suggest?

It is not normal to have goo coming from the cap. Usually a cap will pop and you'll have the top or bottom puff out. Sometimes a cap will explode and you'll have a little more of a mess. So if it looks like goo is coming out if it then that is probab ... Samsung PS42B430 42 in. Plasma TV
