I have had this problem twice, that the high temp shows on the screen, but what happens is that somehow the programing of the temperature setting gets out of its parameters. The repairman used the remote to reset the settings. How can I get into the program to reset?

Re: TV shows high temperature on screen
How old is the TV?
Have you replace the lamp yet?
If you want to get into the service mode to make those adjustments, you can only do it if you have the service manual.
I would suggest to check if the fan is operating properly, or the filter is clean if applicable.
There might also be a temperature sensor that is not working properly or the lamp is giving up on you.

When ”high temperature” shows on the OLED screen, the device is too hot, so place it in a cool, ventilated location. When the temperature is high enough, the device will stop charging/functioning in order to avoid damage.
This device responds to overheating whether or not it is charging.
When the device is charging:
• The device is powered on. When the temperature is higher than 113°F/45°C but lower than 140°F/60°C, it will not show “high temperature” but it will stop charging.
• The device is powered on. When the temperature is higher than 140°F/60°C, it will power off & stop charging. Also the OLED screen will show ”high temperature” at that time.
• The device is powered off. When the temperature is higher than 113°F/45°C, it will stop charging & the OLED screen will show ”high temperature."
When the device isn’t charging:
• Only when the temperature is higher than 140°F/60°C, will the OLED screen show “high temperature” & this device will power off.
Hi Nancy: Error Code F2 indicates
a loose or broken wire on the oven temp sensor or the oven temp. sensor itself is
bad and should be replaced.
Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective.
Hope this helps; thank you for using Fixya. Keep in mind that your feedback is important, leave us some testimonial comment.
There is a temperature sensor, it is called a Thermistor, and they have been known to fail,
It is usually located at the end of the heater fixing plate.
But it could be also a board problem.
You can get a thermometer to test the temp , there is an infrared one that you point at the liquid or article you need to check the temp of,, and it shows the temp on an lcd screen, but they are not cheap.
At 30 however, the water should be no more thal luke warm, if it feels hot, then the temp is not being controlled
OK, what has happen here is, the actual temp sensor has failed during the cleaning process, this has cause a temp that reached a dramatic high range(above 915F-930F). At these temps, there will be major damage that will weld the contacts on the door lock switch mechanism and control board.
If actual over temperature condition occurred: Look for welded relay contacts. If this happens, replace oven control (also called clock or ERC).
If no over temperature condition occurred: Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace sensor if found defective. Check door lock switches for faults as well(welded contacts and burned wiring harness)
Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.
