Why does my sharp Aquos TV go out of resolution everytime I turn off the Wii game that is hooked up to it? Then I can reload Optimum cablevision- all I get is the program guide. Help

SOURCE: Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs

I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.

The TV will connect to your wireless router but not other devices in your network. You can connect to a HDMI port with a cable to your PC and select that port on the TV.

MY SHARP AQUOS 70" TV HAS STARTED TO HAVE A DARK SHADOW ACROSS 1/2 OF THE SCREEN WHILE THE OTHER 1/2 IS PERFECT. DO I HAVE A HDMI INPUT ISSUE OR IS THE TV BROKEN?


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

MY SHARP AQUOS 70" tv STARTED HAVING DARK SHADOWS ACROS 1/2 OF THE SCREEN, THE OTHER HALF OF THE SCREEN IS FINE. DO I HAVE A hdmi INPUT PROBLEM OR IS THERE A TV DEFECT?


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Sharp Aquos LC-65D64U Picture Quality


You need to change your TV's settings and enhancements. Directly from the store and out of the box, the settings are adjusted for easiest sell in the store. That means that:
Your contrast is cranked to 100. Move this down to 50 to 60.
Your brightness may also be cranked up high. Lower it to a level nearer the middle range but not so dark as to lose detail in the shadows.
Your TV is set on "Dynamic" or "Vivid" mode. Pick "natural" or "normal" or standard.
Your sharpness is at least on, if not cranked up. Turn sharpness down or off, and the same with "Edge Enhancement" and "VSM", all to off.

Lastly, I bet you upgraded size and you are now sitting too close to the TV. Roughly, if you are sitting closer than 130 inches (about 11 foot) you might do some rearranging or save some money and get a smaller TV.
