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.......

I have a Sharp LC-46E77UN TV. Remote will start TV green light on. No picture, just stays black. PVR is on and connected to TV via HDMI cable. Cannot turn off green light. Must use power button on TV and...


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.

Sharp Aquous will not turn on.


I would check the System Cable that is linking the box to the TV. Then, press the small button called CLEAR in the front of the box. The button should be behind the flip cover on the front right below the PC input ports.
Let me know if this solution works.

Brand new Sharp Aquous 37". I turned the tv on and a blinking green light comes and goes. I tried to turn it off and the blinking green light still on and no picture and no audio.


Behind your TV, there should be a system reset button.
If this doesn't fix the problem, most of the time this means a part has failed inside the TV. I would use the warranty and take it back and exchange it. You shouldn't be having this problem right out of the box.
I would have them check the new one so you don't have to waste a trip.
Good Luck

Sharp 37 inch aqous tv power button blinking red


If the blinking light seems to be blinking in a pattern, then it is an error code. The end result in any case, is the main power supply is not functioning properly, or the backlight power supply has a problem.

Do you still have this, I need a part myself and having trouble sourcing parts?
Mine immediately goes into standby mode and the screen just shows a white flash. I'm sure its just a power issue.
