My TV won't power up. The round indicator light on the front goes from flashing white to a red 'wait' state. The Samsung repairman said it was either the on board computer or something else. Sansung office didn't know which it could be. Both parts cost about $250/each and he said he would have to buy both since there was no way of knowing. The bottom line was going to about $700 repair bill. The TV is about 2 years old. Should we just dump it and buy a new one? If so is there some place that takes (or even buys) these tv's.

If the power light flashes green for a while then you see three lights come on then suspect the lamp. The part number for the lamp will be located on the side of the TV on an orange and white sticker that says lamp code..
I'm not a TV repair guy but my owners manual states that when all three LED's or lights on the front of the TV are flashing, that the lamp needs to be replaced. Might want to look into this. Good luck!
if your tv is on warranty take it back to the supplier.the problem with your tv is in the power supply there is a open regulator in that circuit along with the H .O. Transistor there is a black that feeds from the HOT to the flyback which also needs to check probably it is also open.good luck my friend
