Re: Turn off 5-6 seconds after I turn on tv
Typical relay power problem on these sets for the relay power. most of the time, its the capacitor in the standby power supply that supplys the main 12 to 15 volts to the relay for the main power supply.. Problem is it is not a repair that can be done or understod by a layman in electronics. its a repair for an experienced tech as a TV set is not a place to be experimenting in.

When was last time you replaced Lamp? Ballast Board is what powers the lamp on.
Lamp Fan, if it is defective it will shut lamp off to protect it, if it is Not cooling the Lamp.
Mats has Lamps for $99.00 1-800-628-1118
Encompass Parts Distribution has 10 Ballast Boards in Stock for $68.96 they also list Service Manual Free for this Model# 1-800-638-3328
This can be from a few things. Either the lamps or the cooling system are failing. or the power supply is not functioning properly. the cost is sometimes more than the tv is worth..shop around..good luck
I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up? I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
I bought a LG 39" flat screen 6 months ago. TV has been working great until this morning. Power comes on for about 5 seconds and then cuts off. Have checked all connections and have unplugged from wall to reset, NOTHING!! And a brand new TV!! Any help would be great!
