I have only had my tv for a little over a year and it will not turn on. I was told it was the main power supply. The one that you hook all your cables to. Part# txn/a1mbuus I cant seem to find this part anywhere without paying alot. Everyone that sells it for 100.00 or less is out of stock.Is their anyway I can bypass this power supply to get my tv to power on? Or does anyone know where I can get one for cheap. Please someone help me!!!!:
