I have a 4 year old Samsung F8500 plasma TV with a blown power supply. Samsung no longer manufactures this part and my old board cannot be repaired. Any suggestions? For an $1800 TV not to last four years is inexcusable. Samsung tech services has been worse than useless. Needless to say this is the last Samsung product I will buy.
Decent TVs are hard to find now. That TV is done. They should have spares for seven years. Boards are only made once, and when they are gone, they are gone.
I would say this expensive gear should be protected. There is a good possibility that this is not Samsung's fault, but your AC power.
If you have expensive gear, use whole house surge protection, a good idea anyway, and supply expensive units from Uninterruptible Power Supplies.
