    I am a Tech here and have been researching this problem---this is a set first made in 2005---I suspect it may be dirt in the optical light engine or a damaged optical light engine(this model uses two different engines depending on version number) I may be able to help you and others if you can take some good photos of what the problem looks like--if you do I will try to advise you---send to etower.766@netzero.net SD TECH

No color only black and white picture and high pitch noise


high pitch noise is most likely the color wheel; pt# for L3 chassis:BP96-00674A pt# for L6 chassis: BP96-01103A
This could also be part of your lack of color, otherwise may also need MAIN or VIDEO PCB

Samsung dlp tv hl-s4266w has white spots on it? How much to fix?


Are they spots or dots? If they are spots then the optics are contaminates. If they are dots either white or black then you have a bad DMD chip. The cost of repair depends on who you hire to repair the set or if you do it yourself it depands who you purcahse the part from.

Samsung HL-R4266W


Yes - I believe a person can with moderate technical skill. I think it's called a light engine. Partstore.com is a decent online resource for parts but it looks a little pricey there. You might dig around and see if you can find one cheaper. It also might not hurt to bug Samsung on the phone about this problem to see if they issued any program/ recall or extended service regarding the issue. I don't believe it will damage anything else, and as time wears on, the color wheel will get slower with colors less acurate on the screen or the bad motor will burn out completely leaving you probably stuck on one color similar to a black and white tv. Good luck and hope you get it fix.
