You should always have all expensive electronics on a surge protector. It sounds like for this set the power regulators blown out as I know this set very well and seen it a hundred times!! its a power regulator IC that cant handle a power surge at all. and if thats your only problem, it shouldnt cost more then 175.00 to 250.00 to repair. Now with a surge though there could be other problems as well but from what you stated Im guessing alls ok except what i stated. Now Please do not attempt to repair yoursels, as these sets have alot of Hi voltage inside them even when they are unplugged.. Good Luck

Skippy is right, you should check the color wheel. There are only two moving parts in the set and the color wheel is one of them. If you listen closely to the TV you may hear a high pitched whirr or whine. If so, you've got a bad color wheel motor. If you are mechanically inclined, take the back off and remove the lamp vent. Take off the screws and cables holding the optical block tray and slide the tray out. The lamp points directly at the color wheel. There is a metal heat sink held in place by two silver screws over the compartment infront of the lamp. Using latex gloves, remove those and the whole color wheel assembly will come out. Of course this process isn't as simple as I've stated it but with some common sense you'll be fine. When replacing the wheel pay attention to the model number. Some of these sets use a bearing setup and others an air cushion one. Make sure you order the right part. If you do order the wrong one, not all is lost, you can (with a jumper) modify it to work. Make sure your gloves are clean and re-install the color wheel, and reverse your dismantle. Good luck!
