Backlight is possible but if it is out you should be able to see that by looking from rear of set---most can be seen---if both are out (usually there are 2) it is likely the power source that fires them or a related issue.

Your HDTV would have to have internet connectivity, either an RJ-45 ethernet jack on the rear panel or wi-fi capability. Sharp calls it the AQUOS NET feature on the TV and is usually an ethernet port. If your TV does not have this capability, you can use a laptop and hook this up to your HDTV. You still need high-speed internet service and a Netflix account.

Do a quick google for this on the AVForums site where you'll find numerous threads covering this problem. First, select the HDMI input before turning on the blu ray player. The handshake over HDMI is the problem. I have the same problem with a Technika blu ray which is fine on my other TVs.
If this doesn't solve it then you ned a firmware update which can be downloaded from Sharp's website and installed using a USB pendrive or by PCMCIA card from Sharp if you have an older model with a rocker on off switch and no USB update port on the back of the TV.

check cables

I realized I had not addressed my display settings to allow out put to
an alternate screen

do you have left and right audio plugs connected?,if no,t you will hear stereo(as it will play threw one lead,but if in mono,you wont hear anything unless you plug the other lead in instead...

Check your owners manual look for the section that tells you how to adjust the televisions features using the on screen menu.You probably Have it set on auto adjust. You must turn this feature off, to use the manual controls. If this does not help go to the Sharp website and search the frequently asked questions and troubleshooting sections. Search for your problem and similar one that may have answers. If all this fails you, call technical service and ask them for help with your problem.Hope this helps you with your problem.

All,

I had the same issue after one month of use. A repair cie came and fixed the problem. It appenned to a neon connector that wasn't properly plugged in the TV.
The Technician explained to me that m TV had 16 neons and a sort of controler for those. Often - from factory - a cable is not sitting properly in its position...

Since I have no problem.

frpm baldmeaney i unpluged my tv same model for 5 min and all was well again . this may work for you . good luck!
