Question about Sharp Aquos LC-46D62U 46 in. LCD HDTV

1 Answer

My Sharp Aquos lc-46d62u has audio but not video. Only a blue screen

It was plugged into a surge protector, but after a storm that didn't cause a power loss the TV is now blue screening. I can get audio. I have tried to switch HDMI ports and still no luck. I also opened the back and made sure all the cables were connected to the boards.

If you are using a box of some kind remove it and the set from power for a while and then plug back to allow both to come on and reboot---blue screen usually means no signal seen..........check the other inputs on set with a dvd player etc.

SOURCE: Flickering screen (LC-52SB55u) with HDMI

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.

How do I connect my Logitech music system to the TV. What connection and plugs is required? Kindly advise.


If your music system is only audio,then you need two RCA type audio cables pair for left& right audio channels(male pin jacks).Connect them at Music system audio output with left & right channels accordingly while on yr TV,connect the other ends to the audio Input jacks(female type). If there is a video out also from your music system then add the yellow video cable as well in the same way.

Tv does not turn on after a thunderstorm and several attempts at power returning to the home. The power went on briefly then shut off several times, now the television will not turn on. We had the tv...


Check the main fuse in the power supply, the TV also has small surge protection devices (MOVs) installed after the fuse, any surges the come along and big enough will cause the main AC fuse to blow. When you surge protector, EVERY connections must go through the surge protector, for example, the AC cord of the TV is connected to the surge protector, the cable connection did not go through the surge protection, the surge then can get to the TV through the cables.

Sharp Aquos 46" HDMI problem


I have a similar problem. The Sharp TV aquos appears to be shutting down my blue ray player and dvd recorder when connected via HDMI. They work fine and never close down when I connect them via the rca cables either single video connection or a composite 3 cable rca lead. I have 3 HDMI inputs on the tv and the problem occurs on all 3. Any suggestions?

Try resetting the TV. Here's how to do it - Unplug the TV's power cable. Keep the Channel Down and Volume Up buttons on the TV pressed and plug the power cable back into the outlet. You will hear a click when you plug it back in if the reset is successful. Hopefully this should restore your video and audio.
