Question about Sharp LC-15AV7U 15 in. LCD Television

Open Question

I have the Sharp LC-15AV7U, and suddenly, when I turn the TV on, the screen flickers, goes black (except a 1" line across the bottom), and no sound. Attached to satellite cable box, which I hooked up to another TV and works fine. I realize it's not that expensive to replace, but has been such a good television, I hate to throw it away if maybe a minor problem. Any suggestions?

Please be aware that this a big problem on this unit. The insulator material used by sharp to between the IC's on the AV board both on top of the boards and underneath the the AV pcb is failing. This insulator is mounted to the IC and under the metal heat sinc. Remove the back and pull the AV Board out of the unit. Use zylene or alcohol and clean all of the grey insulator from between the pins on the ic and order the replacement insulators from Sharp. Most times this will correct the no sound problem. Sometimes this has also damaged the AV pcb and it will have to be replaced. The parts that should be replaced come in a kit with sharp part # PSPKIT663WHZZ. If the kit is not available the 2 parts needed are PSPAZA663WJKZ AND PRDARA216WJFW.

The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

SOURCE: SHARP aquos 1080p HDTV: VCR image flickers when playback

I have the same model TV and the following worked for me. I am using A/V cables attached to Input1 on back of the TV.

On your Sharp TV remote control:
1. Select the Input (1-5) that is attached to your VCR.
2. Go to the menu and select options.
3. Change your color system to NTSC.

This should stop your picture frome flashing on and off.

You still may have a issue with the screen colors. I don't know of a way to address this, other than to make the picture monochrome.

Hope this helps.

SOURCE: Television is not recognizing HDMI inputs

there is a possibility that there might have been a power surge sent over hdmi into the hdmi board on the tv. if on your model the hdmi board is seperate from the sine board then youll have a cheap replacement if not its gonna cost you roughly 300-400 is my guess.

call your repair guy

No picture on intermittent basis -


If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

I have an old Sharp Model # 27A-S100 I have a Black Line running across the bottom of my screen from left to right 22 1/2" length and 3 1/4" in height


If this line does not go all the way across the screen then I will bet you this is an easy fix. Press the menu button on the remote control. The menu will hopefully show up over-top the black. Search your menu for the closed caption setting (usually under audio settings menu) and turn closed caption OFF. Hopefully this fixes your issue. Cheers.

LCD screen


most of the time when you see this it is your lcd panel that bad but it could be inverter. cost converter is around 395 on up and if it is lcd panel not worth fixing. I would call local tv shop ask them how much they charge for estimate . or ask them price on inverter or lcd panel replacement.
