Speaker distortion on SHARP 37" Aquos Hi Def

I just set up my 37 in. Sharp Aquos on Hi Def satellite for the first time...picture is great but I get an annoying speaker "sqwaking" sound on the TV internal speakers just when I change channels but otherwise the sound is fine......there are no other ext speakers or dvd's or anything else hooked up...I have changed all cables leading into it including the Hdmi cable and satellite receiver boxes so it doesn't seem to be a satellite issue....my Sony 32 hi def hooked up in the bedroom does not do this I have had the Sharp tv for 5 years and this did not occur before the change over to hi def ..can someone help me please?

When you are changing channels you are using the tuner of the sat reeiver. the tv does not know you are changing a channel . It is just receiving a constant signal from the SAT receiver. I would suspect a problem with the receiver. Try another one first .

Picture blacks, tv needs to be turned to bring picture back. wii games do not go black


This is caused by your QAM decoder on hi def Sharp sets. You need to rescan for channels, turn off your TV then turn it back on to set to save the channels.The problem lies in the Tuner board and some Hi-Def signals can change frequency slightly due to improperly shielded cables etc. Verify that all of your cables, especially the Cable TV wire are firmly seated on your set. An improperly grounded cable television wire can wreak all kinds of havoc on reception.

Try the main resets in the back by the a/v in and out jacks. If this does not work, call Sharp Customer Service and tell them that you already did the resets. There is a known problem with a heat dissipation pad for the onboard speakers and they will send a repair tech to replace the pad for free, even if you are out of warranty. At least that was the case with my LC-32D6U.

Just bought 42" Aquos but has bad picture quality in Analog & Digital cable


There is no secret to adjusting the picture settings on this unit. My unit is perfect with Hi Def signal and better with Blu Ray. I assume you are using HDMI cables and have tried a new HDMI cable to eliminate the possibility of a bad cable. If you have done this then the unit has a problem and I would take it back or contact Sharp to get an auth. service center involved.
