37mf321d Tv will not turn on. Will not operate with the remote. After unplugguing for 60 seconds (and plugging back in )  the tv screen will start to flash and the power button flashs but nothing happens. If I do this often enough the picture may come back. Right now I have been trying to get it back on for three days. no luck.

I had the same problem with a TV of the same model given to me .The local TV shop had said it wasn't worth fixing. I found a 2200Uf capacitor on the power supply board blown up.I replaced it and the TV works great,it was C2074,I replaced it with a 2200Uf cap at 35 volts,had a 2200Uf at 25 volts in it.I hope this is your problem also.

When I turn on my Sony TV, ti stays on about 30 seconds then shuts off, What do you think is wrong?

Do a Power Reset.
1. Turn off TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.
If issue persists after doing the steps, reset the TV to factory default settings.
1. Turn on the TV.
2. Using the supplied remote, press and hold the UP arrow button.
3. While holding the UP arrow button press the POWER button on the TV itself.
4. When the TV goes off, release the POWER and UP arrow button.
5. The TV will turn on by itself and the initial setup screen will be displayed. Just follow the on-screen prompts to finish the setup.

My 39 inch tcl led TV power cord got abrubtly unplugged while watching TV. Plugged it back in and now the TCL logo on the start up screen stays there frozen. Many times already tried to unplug it, wai

Unplug the tv and hold the on/off switch on the tv (not remote) for 30 seconds. This should clear any power left in your electronic boards. Then plug it back in and try again.

My tv is not working right with picture.

Press the TV button on the remote, make sure the TV is plugged in, check the electrical outlet to make sure it is live if the TV does not turn on. If these actions do not solve the problem, press the Power button on the front of the TV. If the TV turns on, replace the batteries in the remote control and reset it by pressing the number 1 button for 60 seconds. If necessary, reprogram the remote.

Unplug the TV for two minutes, then plug it back in if the buttons on the remote don't work. Make sure the remote is in TV mode.

Change the settings on the sleep timer if the TV turns off unexpectedly. Unplug the TV and wait five minutes before plugging it back in if necessary.

Check your antenna connections and cables if the sound is okay but the picture is poor. If all the connections are good, adjust the sharpness function.

I bought a new TV for my #2, but is says I'm not getting a signal when I hook it up to the cable. I have it on channel 60


You can go to TV 1 to make sure TV 2 is suppose to be set to channel 60. Did you run the auto setup on your TV? If you have already run the auto setup on your TV, unplug the receiver from the electrical outlet for 10 seconds and then plug it back in. This will make the receiver reboot and re-acquire satellite signal. Then see if you get a picture on your TV 2. If not, the last thing you can try is changing the channel from 60 to 73 through the receiver.

With your DISH remote at TV 1, press the Menu button - Main Menu will display on the TV 1. Then press 6 (System Setup), 1 (Installation), and 5 (Modulator Setup). On the Modulator Setup screen, move over to TV 2 Out and select Cable, then press select on the remote. This will automatically change the channel from 60 to 73. Highlight Done on the right and press select. Cancel out of each screen till you get back to the TV screen. Go to TV 2 and put the TV on channel 73. You should get a picture. I hope this helps.

I chose the wrong channel on remote it took me to a Dish site whcih I chose to exit - when I did that my picture totally disappeared - could not get it back. It is fine on my other tvs - so I need to get...


Are you getting a snowy/blue/black screen on your TV? To get your picture back, you need to get the TV back to the correct channel or input. If the receiver is in the same room as this TV, the TV should be on channel 3/4 (normally 3) or an input setting depending on the TV. TV 2 (away from receiver) would be on channel 60/73. If you have the TV remote, put the TV on one of those channels. If you get a picture when the TV is placed on the correct channel, press and release the SAT button. This puts the remote back in SAT mode and will now operate the receiver.

If you don't have a picture, unplug the receiver for 10 seconds from the electrical outlet and plug back in. This will cause the receiver to reboot and re-acquire Satellite signal. i hope this helps.

The only way that I know of to eliminate this problem is to buy a new TV. My ILO TV has been repaired twice since May 08 and it went out again for the third time. The problem starts out as an intermittent problem.... You turn the TV on, the audio is fine but there's no picture, you will be unable to change the channel or volume whether you're using the remote control or the buttons on the TV.
This TV should have been recalled. Don't reward the manufacturer and retailer for their bad behavior, buy your next TV from a different retailer.
