Will not come on


First make sure there is power in the socket you are plugging the unit into. If that's OK and the unit has been plugged in then 1) Disconnect the TV from the power by unplugging it from the wall socket. 2) Wait 20 minutes and then plug it back in. 3) Turn it on and see what happens.

I've seen a number of LCD TVs some back to life if these three steps are taken. It allows the TV to reboot itself after all internal capacitors are discharged.

Unplugged tv and when plugged back in doesn't come on


Hello
If you have unpluged the TV from wall socket and it doesn't come On when you plug in back, either its power supply system or its stored memory has the trouble. Look whether the power indicator light coms on. Ensure that the main power ON/OFF switch at the front panel of the TV is ON. If the front panel power switch, control switch of your wall socket, and all the other electrical connections are OK, and still the TV doesn't come ON, surely the power inverter baord has the trouble and must be either repaired or replaced. if the power indicator light comes on, and your TV doesn't come ON by remote POWER ON button, the settigs that were stored has vanished, and resetting it to its original setting is necessary. Follow its manual for 'initial setup" and so all the recomended setting there. OK.

The tv came on then the screen went black but there was still sound for a sec. Now the green light keeps blinking and the tv won't turn


Unplug the tv for 5 minutes, then try this. Keep holding the VOL+ and CH- buttons down while you plug the tv cord back into the wall ac outlet till you get sound and picture for a second or two. You should be able to turn the tv on and off with the power button now. Next turn the power button off and unplug the tv for a few seconds and then plug it back in and turn the power button back on. Watch the screen and see if the sound and picture comes on, best to check in a dark room to see better, if sound stays on and picture comes on a few seconds and back off you have a bad CCFL backlight lamp in the LCD panel. This tv hads (10) CCFL lamps part # RLMPLA029WJN1 cost $15.93 at www.partstore.com or $19.49 at www.encompassparts.com in it and if one is burned out it will not let the tv picture be powered on till it is replaced. To check and replace the CCFL lamp you will have to unplug the ac cord from the tv back and remove 10 screws holding the back on. With back removed unplug the wire plug on the power button circuit at top left side of the black LCD screen trim, remove 4 screws holding the top of black trim, lay speakers off it, and release trim clips, (4) at top and (2) at bottom with a flat screw driver, and lower the trim to unclip the LED circuit board at bottom left side on the trim. With trim removed, at top of LCD panel remove the (2) PC ribbon wire clips with thumb nail by lifting up on it to release the flat PC ribbon wire. Lay the tv back on a soft pillow with screen up, and look on the LCD panel front for and remove the (10) silver screws 1/2" long with an arrow mark beside them. Do not remove any gold colored screws or any without marks. The LCD panel screen can now be lifted off, lift the backlight plastic thin sheeting and thick sheet off to see the CCFL lamps. Plug the ac cord back into the power supply inverter circuit board and plug the power button plug wire back in its circuit board on the LCD black trim panel, and power the tv on while looking at the CCFL lamps. If the lamp is dim or burned out, take the (2) white plastic covers off the ends of the lamps with a flat screw driver and unclip the lamp to replace it, Check the lamp socket part # QSOCFA003WJZZ by putting a good lamp in it and if it lights up the sockets are good and the bad lamp was the problem. If all the CCFL lamps do not light up, unclip the top lamps and move them to differant sockets to the center and the center lamps to the top, if the lamps do not light up, then it is a bad power supply inverter circuit board the ac cord plugs into, part # RUNTKA448WJQZ , cost about $160.00 for new one or less if you buy a used one on www.ebay.com , replace it and the tv should work ok then.
