Liz's TV wont turn on. The indicator light is on (means it's off). Earlier this week, it would click and go into standby mode when she tried to turn it on. It's a 36" Hisense LCD. Today I went there and the indicator light was blinking. I pushed the power button on the TV and it turned on and worked BEAUTIFULLY for 3 hours. When we turned it off, it went back into clicking and blinking mode and would not turn on. Three hours later, after changing all wires, replacing batteries in the remote, calling FIOS, I gave up. I noticed that the screen was pretty hot after 3 hours. Any ideas? Other than calling Hisense?
Unplugged and replugged everything. Changed batteries in all remotes. Called FIOS
How old is the set?
Did this problem occur after a storm or power outage?
The most common cause of this problem in these sets, is failing capacitors in the power supply. They are similar to batteries, in that once they are charged, they can continue to run inedifinitely, but once they receive several surges, the resistance gets so low, that they act as a short, and can intermittently shut down. The solution is to have the capacitors replaced. Average cost for this type of repair is around $200 parts and labor.

Yes, I got that much info (about the capaciters) from googling around. But why did it work well for 3 hours until we turned it off? ...and is the hot screen consistent with this problem? Also, the only click now is when I put the plug back in. Before It would click when I plugged it in, then when it went to standby. So do you think I cooked the capacitors for the last time during today's operation? Do you know if Hisense warranties these TVs?
The manufacturer warranty is one year from date of purchase.
Capacitors are funny, in the fact that they can operate indefinitely.....then simply fail to recharge the next time the TV is powered up (due to a shorted/dry cell, or leaking of the electrolytic fluid).
All of the inner workings of the TV can operate hotter than normal in this case, because they are no longer receiving the rated voltages and are starved for current.
The power supply is now sensing the short in the cpas and not allowing the set to power up.
