HELP!!
For several months, we experienced the screeching noise that is associated with the color wheel. This item was purchased and installed approx 3 weeks ago. I also ordered a lamp as my picture was dim. After gathering all available information, I then replaced the color wheel and the lamp. The tv came on just fine with the exception of the colors being reversed due to replacement of the color wheel. After more research, it was determined that jumper CN810 needed to be removed. To locate this jumper was quite difficult, however, after removing the heatsink fan and spring clip, I found the jumper and removed it. The tv powered on and did just fine for 2 days. While watching it, it simply powered down and all lights on the front began flashing.
spoke with Samsung once more and was then told it was possible it could be the ballast. So, a ballast was ordered. This latest part was installed and I attempted to turn on the tv again. This time, only the lamp light flashed while the tv tried to power on. The color wheel spins up (it can be heard), the ballast clicks and then the tv shuts back down. I then called once more and spoke with another tech, but no new suggestions were given except to have a service tech come out and try to repair it.
After reading some of these posts, it sure seems like either my new lamp is bad, or I need a different fan??? Any help would sure be appreciated - I am extremely reluctant to sink any more money into this TV without having a clear idea of what needs to be done.
