I have a 50"Toshiba smart tv and the tv wont respond to the remote or the control panel buttons. Once i disconnect and reconnect the power source it shows Toshiba and then the screen is dark blue.

To disconnect your Fire Stick remote from your TV, you can follow these steps:

1. On the home screen of your Fire Stick, go to "Settings" in the top menu bar.
2. Navigate to "Controllers & Bluetooth Devices" and select "Amazon Fire TV Remotes."
3. Select the remote you want to disconnect and then choose "Remove."
4. Follow the on-screen prompts to complete the removal process.

To reconnect your Fire Stick remote to your TV, you can follow these steps:

1. Turn on your TV and make sure that it is set to the correct input for the Fire Stick.
2. Press and hold the home button on your Fire Stick remote for at least five seconds.
3. Wait for the remote to pair with your Fire Stick. Once the pairing is complete, you should see a message on the TV screen confirming the connection.

If you want to disconnect and reconnect your Fire Stick to your Element TV, you can follow these steps:

1. Unplug the Fire Stick from your TV's HDMI port and power source.
2. Wait for a few seconds and then plug the Fire Stick back into the HDMI port and power source.
3. Turn on your TV and switch to the correct input for the Fire Stick.
4. Follow the on-screen prompts to complete the setup process.

Once the setup is complete, you should be able to use your Fire Stick and remote as normal.

its the power pack in the tv that has gone out...contact the manufacturer for either the part to replace it your self or for a technician to repair it.

If the TV displays the menu or Smart Hub when you press the button on the remote - the TV is on, it's just displaying a black screen. Change the Source on the TV to another input. See the page on Samsung TV has No Picture for more troubleshooting steps.

Depending on the TV, there will be a Jog Controller or TV Control Stick that will allow you to access the TV menu and change the source. Use the control on the TV to select an option - toggle it left or right to see if anything appears on the TV.
If the control menu appears on the screen, the TV is on but not displaying any input. Check the connections or change the input source on the TV. If the controller button works on the TV, but not the remote, check the batteries in the remote control.

Unplug the TV from the power source and leave it for a minute or two. Reconnect the power cable directly to the wall rather than a surge protector. If the TV Standby light appears - the TV is receiving power. If the Standby light still doesn't appear, please get in touch to organise a service.

Some Smart TV remotes require you to use the keypad to spell out letters, just like on phones. Pressing the "2" button once gives you "A", twice gives you "B", three times gives you "C", pressing the "3" button once gives you "D" and so on. See if that works. If not, you need to connect a keyboard to your Smart TV to enter the information.

consult the owner manual or call Samsung---this set likely has a lockout feature that locks both the remote and the keyboard out.

You might also want to research this by taking the model number and Google key words "remote lockout" etc.

put your remote down and dont use it. disconnect the power at the plug. wait 30 secs. reconnect the power at the plug and use the ON button of the TV, see what happens. only then try remote. a TV is never OFF unless its power is disconnected even when the remote tells it to go off, its still in standby and what it needs is a proper OFF for a while.

There is a known problem with Toshiba Tvs that options change with out any input of buttons or remote. the tv switch panel needs replacement. This is situated behind where the buttons are on your tv usually bottom right. there is a work round if you dont want the expense of part replacement. you can disconnect these buttons and only use the remote. This requires taking off the back (ensure tv is disconnected from power as there is high voltage in the tv) once the back is removed and tv is laying on its front you will see bottom left where the buttons now are, a couple of cables one will have seveal wires and one will only have a couple of wires take the smaller one off this will disconnect the buttons and stop the problem. once this is done you can only use the remote control to control the tv settings but the power on off button still works.
I hope this was useful.

If the TV stops responding to the controls on the remote

control or TV control panel and you cannot turn off the

TV, press and hold the POWER button on the TV control
panel for 5 or more seconds to reset the TV.

hope this helps

I had a similar problem: my WS-55511 would not respond to the remote and the front control buttons (with the exception of Power) cycled through the Device Menu. I solved this problem by disconnecting the front panel. Here's how to do it: 0. Unplug the TV
1. Remove the speaker grill from the front by pulling forward: there are no screws. 2. Disconnect the two cables that are exposed after the grill is removed. 3. Plug the TV back in, wait for 5 minutes to reset. 4. Try using the remote.  Hope this helps! 

1. Disconnect your player from its power source for thirty seconds 
2. Reconnect your player to its power source 
3. Press the Power On button on your remote control 
4. Press the Enter button on your remote control 
5. Press the 8 button on your remote control 
6. Press the 4 button on your remote control 
7. Press the 2 button on your remote control 
8. Press the 6 button on your remote control 
9. Press the 9 button on your remote control 
10. Press the Enter button on your remote control 
11. Your player should now place itself in Standby mode 
12. Press the Power On button on your remote control 

It should also work for HT-Z310T and HT-510T and its variantes...
