DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.
Acoustic Solutions 32 lcd hd Tv screen has green/blue contrast shadows all over the light images on the screen. I have tried changing all the picture setting to no avail.
Check and replace the following on the smps:
Cs-860 & Cm-860 1500uf/10v With 2200uf/16v Cm-856,Cm-858,Cs-859,Cs-861 With 1000uf/25v Replaced Cm-854 & Cs-857 With 2200uf/25v
then let me know if it will power on...
