I have Samsung HL-S4266W DLP. It's about 1 year old. Just began seeing what appears to be 'haloing' on all channels. My neighbor calls it 'crunching'. It doesn't matter what source I use (ie...ant, cable, HD or otherwise) it still has the problem.

HI, Could be caused by alot of problem, first why in h#$% did you by Samsung, the haloing, my be cause by bad power supply, by y board, what tech do is change one board at the time, I would change the board on the left hand side whitch is the y board, then power supply, if for any reason it doesn't regulate proproly, it will make this problem.

I hope this help
