Unplug it for an hour to let it reset itself, if still bad then it may be sensing short circuits in the power supply or in the backlight inverter circuits, it can be the main board also. You need to do some voltage checking first.

TROUBLE SHOOT LC-60E78UN TV


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.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

My Sharp LC-40CT2E has suddenly gone off. There is no picture and attempts to turn it back on are met with nothing. The sensor light is flashing continuously. The TV is approximately four years old.

What do you press to program remote to sharp TV


0079 0123 0063 0020 0004 0009 0226 0266 0006 0095 0122
Direct Code Entry
  1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
  2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
  3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
  4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

    Code Search Method

    1. Manually turn on the device (TV, VCR, etc.) to be controlled.
    2. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
    3. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks once, then stays on.
    4. Press the CHANNEL UP button repeatedly (up to 300 times) until the device to be controlled changes channel. The red indicator blinks, then stays lit.
    5. Press and release MUTE to install the code. The indicator light goes off.
    Most users will want to store VCR codes under the VCR button, Cable codes under CBL, etc. If you want to store a VCR code under CBL, etc., first follow the procedure for Direct Code Entry and press CBL in step 2 of Direct Code Entry, then enter ANY VCR code in step 3 of Direct Code Entry. Then follow the steps above for Code Search.
    IDENTIFYING CODES FOUND USING THE SEARCH PROCEDURE
    1. Press and hold the SETUP until the LED indicator lights steadily. Release Setup button.

    3. Press and release SETUP. The LED blinks once.
    4. To find the first digit, press each number button from 0 to 9 until the LED blinks. The number you pressed is the first digit of the code.
    5. Press each number button from 0 to 9 again as above to find the second digit.
    6. Press each number button from 0 to 9 again as above to find the third digit.
    7. Press each number button in turn to find the fourth digit. When the fourth digit has been found, the LED goes out.

No picture, but power is on...


How many times does the POWER led blink per sec? (dont worry about the OPC)

2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
