How to get a sharp tv off of repeat mode - Sharp Aquos LC-19D45U 19 in. LCD TV

Hi,

First, please check that your one of your tv remote buttons isn't stuck because this could cause your tv to continuously go into a certain mode.
You might then attempt to factory reset your tv to stop the service-mode issue. Please reference your device's manual to help with this. Thank you.

You need to reboot the tv. you've had a signal drop which locks up the tv. call sharp tech support and they will talk you through a reboot.

Sometimes the main board causes the failures of other boards. This can only be determined by process if elimination...

Auto demo mode?

This may help you...you can also get an owners manual free on line.

Make sure that you have turned on the tv before you begin programing your Uverse remote control.

Hold down the TV button on the Uverse remote. (If you are trying to program a different device, hold down the button that names that device). As you are holding the TV button, press and release the OK button. You know you have done this right when all the mode keys flash twice.

Find the 4 digit code for your device

At this point, the TV mode button should flash three times. Try to turn the TV off by pushing the power button. If it does not turn off, try a different code. The manufacturer of your TV has many codes.

If none of the codes for your device work, try manually searching for a code. Go back and repeat steps 1 and 2. Then enter 922. Hold play as the remote cycles through various codes. When your TV turns off, push enter.

---------------------------------------------- ---------------------------------------------- Sharp TV codes for at&t remote: 1004, 1009, 1011, 1025, 1064, 1077, 1078, 1081, 1097, 1099, 1153, 1157, 1274, 1298, 1311, 1312, 1362, 1375, 1378

Power board is detecting an 'over-or-under-voltage' condition from other circuits. Could also be high dc volt shut-down. In either case, the tv is in protection mode to stop further damage this is why it flash an error code 4 times. Each number flash intervals tells the tv-technician what area the fault may potentially be. take it back if its under warranty, or have a repair shop near you fix it.

first try new batteries and be sure you have pressed the AT&T mode button at the top left of the remote - if you still have issues then on the sharp tv menu - turn off any energy saver mode, Optical Picture Control, taking the picture mode from dynamic or vivid to standard, and if that doesn't work - try changing the backlight settings if your tv has one.

On the remote control, press and hold the appropriate mode key (TV button) until the four mode
keys flash twice. The mode key will continue to flash.
Enter the three-digit code. See above I gave all the Sharp codes.
After you press the first digit, the mode key should light and stay on. After you press
the last digit, the mode key should flash three times and turn off.
If the mode key does not flash three times before turning off, the code is invalid for
this device type. Repeat the procedure with another device code.
Point the remote at the device and press POWER. If the device turns on or off, you
have finished programming.
If you have tried all the codes listed for the manufacturer and the device does not
respond, refer to the CodeScan™ section later in this manual.

Yah get out of old technology.
