I have a Sharp LCD TV Model # LC 32SB220U. When you turn the power on, within a minute or two, it clicks off. I have tried everything in the instructions to troubleshoot the problem. I also reset to factory settings. Could you give me any ideas on self fixes for this problem? The TV is about 1-2 yrs old. Thanks for any help you can offer.

Check the high voltage circuit on the board that has the 120 volts input. The high voltage should be close to 400 volts - nothing less than 390 volts. The capacitor is failing to hold the voltage and needs to be replaced.

Call sharp back again and tell them you first want to register for aquos advantage program, which is free. By doing that your service will go much quicker with them. You then tell them that you want to get set up for service. They will have one of their authorized professionals come and fix your tv in a matter of days. If their tech cannot fix it, they will replace your tv free of charge as long as you are within your warranty.

SOURCE: My Sharp TV will only hear sound. No picture or images even from the tv menu setup option. Model# LC-19SB25U. About 1.5 yrs old. Converter box ok.

In most cases, you can reset the TV by leaving it unplugged for 30mins.
If this doesn't work, I believe the circuit board that supplies power to the screen maybe bad. They call this board a backlight inverter board. It would most likely cost more to repair than replace the TV .

SOURCE: Sharp 60" LCD Model LC-65D64U.

Does the blinking pause for a short time after blinking a certain number of times? Just checking whether the self-test diagnosis is able to detect the source of the problem.

My 32-inch lcd tv from sharp has no picture but audio works fine. No picture ever comes up, not even the "please wait" message. Whats going on?

My 3 year old Sharp LC-40C32U would start up fine but within a minute would go dark (audio continued fine). For a while I could turn the set off and on again and it would be fine, but over time this became less effective. My solution, which has worked for a week now, was to a) unplug the set's power cord; b) after 3 minutes plug it back in and turn the set on; c) on the remote hit MENU and slide over to SETUP (3 clicks to the right if the screen is dark) and one up to RESET; d) hit ENTER and follow the prompts. This puts the set in it's factory configuration so you will have to rescan for channels. Worked for me.

Sound doesnt come out of tv when hookedup to cable box sharp tv

You must use the video and audio with their own separate cables. The sound is separate.
If you are following proper procedure, then you should contact the tech support for your set to find out if there is a defect somewhere.
