Question

Hello,

I too have an issue with my Samsung, I been told by a cutomer rep. for Samsung that he would replace the color
wheel first. But, my concern is what if its the ballast.

When it first happened I heard a pop, then color started to fade. I turned it off and turned it back on the next morning. All three lights where flashing, so naturally I bought a lamp.

after putting in the new lamp, the signal just flashed lamp as if it was coming on...started vibrating really bad and then would shut it self off and automatically try coming on again.
The only way to stop it was to unplug.

What do you think? color wheel or balast, they are both exspensive and just can't afford to keep replacing parts.

Thank You

My Answer

I would say that this is your color wheel. The ballast is an electronic device that powers the lamp and has no moving parts. If that was to go, the lamp wouldn't light at all.

Also, any thing that could happen to a ballast that involves a "pop" would probably involve smoke!

The color wheel spins at thousands of RPM, so vibration makes sense to me.

So, given these symptoms, I'm going with color wheel.
