My Sharp LC-60TQ15U is behaving weird for a week, it switch on via remote and then stop responding to remote. Suddenly menu comes and selects picture settings on its own.

Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/ Before replacing it, try a reset to this set, and then check.
There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Sharp aquos will not turn on


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

I have a Sharp flat panel model LC-20SH4U. The units power LED light is red. No effect (sound or picture) when remote or on/off switch is activated. The LED light slightly blinks.


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.

1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope this may help;

How do I stop the CC on my Sharp Aquos


Sharp Aquos LC-37G4U
Try the remote.
On the remote is a button labeled CC near the bottom.
Press the button to access a menu to switch off. Each time you press the button it will toggle among the choices.

If the tv has problems, try turning it off and unplugging for a few minutes to reset the EPROMs.
Plug in and turn on. Repeat the above.


If you want to change the size/color of the font you can get into menu mode by pressing the menu botton in the center of remote.
Next use the and > arrows to get to OPTION menu.
Use the ^ and v arrows to get to the Caption Setup menu and press Enter.

We have picture, but no sound; it is not the cable box. Suggestions?  We were watching the TV when suddenly the sound went dead.  Messing with the cables in the back brought it back temporarily,...


Try changing the cable. Is it a red and white composite audio cable or an hdmi cable? Try resetting the tv to the factory preset values. On the tv remote press the menu button and scroll over to setup. Scroll down to reset and press enter. Select yes then press enter. Select yes again then press enter. Then after the tv restarts go back to the correct input. I do recommend trying another set of cables if jiggling them did cause the sound to come back once before.

Are you using a remote from a cable issued cablebox or the orginal remote? I noticed my cable company DVR remote stopped working when the OPC setting on the Picture menu of the TV was set to the 'ON' position. Once turned to the 'OFF' position it stopped the OPC feature from activating which seemed to interfere with the response of the remote for some reason.

SHARP AQUOS LC-26P70E - Clock


Most TV's don't change with daylight savings time, since they do not operate with a date, just time. You will need to change it via the remote.
Good luck
