Question about Televison & Video
I tried unplugging, then holding the power button for 60 sec., then turning it on. I also tried unplugging all chords, and replugging to reboot, but still no luck.
The main board has an issue its usually a eprom but thats hard to replace without alot of soldering skill. However you can replace the main board they are available from www.tvrepairworld.com

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

SOURCE: It won't turn on
I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

Depending on what made the power outage, your power supply might have got fried. It might be as simple as a few capacitors blowing or a little more serious. I would suggest taking it to a repair shop. A power supply replacement will run you about 200-250. If its just a few capacitors, should be around 100.

This going to be tough one to figure out, but at least the back light inverter board and power supply are working, unhook it at least 1/2 hour?
You may have bad main logic board problem. Try reading my guide here and see how much the main baord may cost you.
