Tv will not power up



Press the TV button or ON/OFF button while remote is in TV mode and there's a source of power to the outlet or outlet strip.

Make sure the TV is plugged in.

You might have tried to turn on the TV during the lamp cool-down. Wait a few moments and the picture will appear.

Has the power light on the front of the TV been blinking for one minute? If so, the lamp may be dead. Refer to the Power indicator
is blinking or flashing section below for more information.

When you first plug your TV into an outlet, the Power indicator on the front panel will light and blink for approximately 30 seconds
and then go off during the initialization of the TV. This happens only when the TV is unplugged and plugged back in. The TV can
only be turned on after the Power indicator goes off.

Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else, such as a lamp.

Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the
remote control solutions on page 53.

Multiple TV Setup might be set to the wrong option. Press MENU/OK on the front panel. Select Setup Options, then Advanced
Options, then Multiple TV Setup. Choose TV (default).

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.

Sony kp-65wv600 projection tv error code. My tv blinks 7 times.


Hi,
The Standby LED blinks when the TV is turned on, then shuts off when the picture is displayed. If the LED blinks continuously, this may indicate that the TV requires service. Before getting the TV serviced, try power resetting the TV and factory resetting. Try the below steps also: Connect the TV to a different wall outlet and check if it helps. This is to check if the issue is with the Power. Disconnect the TV from the Power Strip or the Surge Protector and connect it directly to the Wall outlet and check if it helps. To Power Reset the TV, disconnect the Power cord for a short period of time (approximately 1 minute). Then, reconnect the Power cord and power ON the TV. To factory reset the TV, turn it ON. Then while holding down the RESET button on the Remote Control, press the Power button on the TV front panel. The TV will turn OFF and then turn ON again. Then release the RESET button to complete the reset procedure. If the issue persists, service may be required.
Good Luck!!

If ever resetting is no effect then the problem is in the "DM board"
The constant blinking green light means that the TV is not booting up. This is a common problem on this set. Hope it may help you; Regards, VOTIT
