20 Most Recent Sharp Aquos LC-37GD6U 37 in. LCD HDTV - Page 3 Questions & Answers

I've had this problem with my Aquos. I had Sharp send out a tech. and they upgraded the firmware on the motherbd. to version 1.04 (main and monitor) and this took care of the problem

Pull batteries out of the remote control and keep it that way, just to see if maybe power button on remote control is being pressed/faulty. Also check the auto turn-on option of your TV, it might be set to a specific time to power on/off. This would be noticable if TV is powering on at specific time of day.

When I first bought my Sharp Aquos 42 inch TV...I started having sound problems...turned the volume way up to 60 maximum and could hardly hear it.
Then after the TV was on for 4 or 5 hours, there would be crackling chirping popping noise. It seems after the TV heats up for awhile...there is MAJOR sound problems.
So I was advised to buy a Sony surround system and connect it to my TV...deactivate the TV volume and use ONLY the surround sound. I did that...but the surround audio cables are connected to the back of the TV and I get the exact SAME problem with chirping and crackling sounds after the TV heats up.
SHARP IS NOT BEING HONEST WITH CUSTOMERS.
There should definitely be a RECALL on the sound board.
Replacing it does nothing....the overheating of the TV just damages the new sound board and the TV has to be repaired again and again.

Well, I'd make sure that there are no remotes in the vicinity or that their batteries are removed and then let the TV run to see if it still happens. If it still happens after the remotes have been removed from the equation, then you are probably dealing with a stuck button on the TV or a prankster.

Those lines are because of "Interlacing". a REALLY bad case of it. what are you watching when this happens?

you need a antenna with digital capabilities.you can generally find them cheap and make sure tv is set on antenna instead of cable.

Your PS3 set itself above the max resolution your LC-C3237U. Most likely the PS3 is doing 1080P, but the highest the Sharp can do is 1080i. So do this:

1. Connect PS3 to TV (you can use the current cable or analog cable)
2. Turn on TV and set input to port PS3 is on.
3. Make sure PS3 is connected via correct cable.
4. Power on PS3 via power button and HOLD IT for 5 seconds (release after the second beep). It should automatically configure your PS3 to the TV's native resolution for all settings. I’m happy to assist further over the phone at https://www.6ya.com/expert/kevin_c38b47f462e94458
