Sharp aqous lc 37 in tv power no picture,sound

My sharp tv will turn on(power button glows green), but no picture, sound, just the black screen.  The input info. comes on for about 5 seconds in top right corner, then shuts off.
Also, my nephew borrowed the tv and while he was away it was in a room with no heat, at about 50 degrees.  Would this cause the tv to stop working?
Thank you

    my 46" aquos does the same thing. while in the middle of watching tv or movies it will go black for a couple seconds and then the input/channel display will show up in the upper right corner for a couple seconds.

    I have exaclty the same situation: LED becomes green, but no picture, no other functions work except turning it off again. To solve the problem, I have to take off the power chord an reconnect it. It usually happens when the TV was not used for a longer time (>1 day?).

    Same problem with Sharp 32" LCD TV, just a few weeks old. Randomly the green light indicating power on will come on, but no picture or sound, screen remains black. Today even the power button on the TV would not work; i.e. when pushed, nothing happened, the green light and black screen remained. Sometimes the green light will begin to blink slowly. The only way to restore operation is to unplug power for several minutes. When plugged in it will operate properly for a few days, then the same conditions occur again.

Your control board seem's defective or the inverter board (associated circuits) are bad. This is common in most TFT-LCD Tv's.......

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

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.

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.
