How to reset the television to the original factory settings.
Article ID: 42994 ' Last Updated: 08/15/2015
WARNING: FOR LCD AND PLASMA TELEVISIONS: This procedure will reset the video calibration settings of the TV. If you paid to have your TV screen specially calibrated, you may want to first try performing a power reset instead. Otherwise, any special calibration settings will be lost. A Video Tutorial is available with information about this topic.IMPORTANT:
The supplied remote control is necessary to perform this procedure. Then be sure to point the remote control towards the front and center of the television.
If lights on the front of the TV are blinking or flashing, follow the steps in this answer.
Unplug the TV power cord from the electrical outlet.
Allow the TV to remain without power for one minute.
Plug the power cord back into the electrical outlet.NOTE: The TV should turn on automatically. If it does not, turn it on.
Wait approximately 40 seconds for the TV to completely start up.
On the TV remote control, press and hold the UP ARROW button.
While holding the UP ARROW button, press and release the POWER button on the TV set.
The TV may turn off and then back on.
The button may be on the front, top or side of the TV. If your TV has an Energy Saving switch, be sure to press the POWER button rather than the Energy Saving switch.
Release the UP ARROW button.NOTE: The initial setup screen displays if the above procedures were performed correctly.
Follow the on-screen instructions to complete the initial setup.
IMPORTANT: If the reset did not complete successfully, disconnect all devices from the TV and turn off or disable the network connection the repeat these steps.
If the model here listed is correct it may be the actual power switch--it like all the front controls is a tiny micro switch--only supposed to work when pressed but can and does fail in this way--
How to prove/disprove this?
Someone needs to remove the front keyboard and unsolder that 2 pin switch---remote will with the board back still turn set on.
If it works that way either just use the remote or search for the keyboard and replace if can find one.
Only other issue possible is the microprocessor in the set could be bad and we do not want that-----both the front buttons on set and the remote go to the same place inside the set but the keyboard has priority over the remote.
If power button bad, button on the remote will not stop or correct this.
The clicking noise that you are hearing is actually the power relay. Normal operation by either the remote or the power button on the front panel, you would normally hear a soft click just after the press of the power buttons to turn the unit on or off. When you initially plug the unit in to power, you will hear the same click noise. Being that you are hearing it all the time indicates a failed relay. TV's now a days, or at least ones built during the last 15 - 20 years have different Printed Circuit Boards (PCB). There are PCB's for power (which youre dealing with now), sound,video and so on. The PCB that you need to repair your clicking issue will run you about 80 U.S. dollars for the part plus the average going rate for repair from a qualified service tech. You could purchase the part from Thompson Consumer Products repair and fix it yourself, but be aware, there will be no warranty on the part itself unless an authorized tech does the work. Located on this PCB is the power on/off relay, fuse, usually 4-5 connectors for power to different PCB's (depending on model and features). Now depending on how old the TV actually is, you may want to invest in a newr set, the reason why I say that is, is because the new power unit may and can overload the other boards and cause damage to them and now you have a new problem to deal with( along with more money being tossed down a hole.
Error code 12 means normal operation.
On these models we have found that a switch is sticking on the control panel not allowing the set to turn on.
Disconnect the control panel. You will be able to use the remote on it.
To find the plugs for the control panel:
Remove the speaker grill and front panel, then follow the wire to the connection.
Remember to unplug the set before putting your hands inside of it.
Tell me how it went.
Take off back cover. The problem power board is to the right of the
board where the power plug feeds into the TV. There is a large white
fuse right bend the power plug. With a meter it read ok; about 8 inches
deeper into the TV on that board was the resister next to two fuses. My
4 amp 125 volt fuse did not read on my meter. After replacing, it
