Having problems with your Flat Panel 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.



Answers :

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.

I have a Samsung HLP 4674w DLP. The picture started to lose color and look like a negative image. Then it would get scrambled and eventually go out. Powering on and off sometimes fixed it, but only temporarily. Sometimes it would also turn off and on by itself. I thought it may be the lamp so I replaced it, but it did not fix the problem. Next I thought it may be the color wheel so I replaced that, but the problem did not go away. Also when this happens the Power switch will not turn the TV off.

SAMSUNG PN42A400C2D 2008 model In the past 3 months tv has started turning the volume all the way up & down by itself. Sometimes it stays at the highest level and sometimes it does not. I can eventually get the volume to stop moving with use of remote. BUT... now (this month) it is also changing channels all by itself too & it will not stop even with use of remote OR buttons on the side. Also while I am watching tv a box will pop up that says something like (this action/function not available).
