Perhaps one or more of the cooling fans are inoperative. One of the fans is easily accessible by removing the two screws that hold the grille cover on the left side of the set. When you power up this is one of the fans that should kick on. The other fans require removing the back panel and probably will require a service tech for replacement. You can enter the service mode by pressing "Menu"- 619 -"Menu" and going to "INFO" on the menu bar. You can check your system temperature and it may indicate which of the fans is not working.

Why does it shut off completely and has to be manually turned back on?


Probably a safety feature to keep it from getting too hot. temperatures above a certain level could easily start a fire.
This unit has a temperature control with will turn it of after a certain temperature is reached it also has a timer that will turn it off.
It might also be a malfunction in one of those controls.

Chest freezer suddenly stops working then will start again later


This is normal if your freezer is in good working condition. If your compressor runs constantly then there is a problem. Once the unit reaches the set temperature the compressor shuts down. The set temperature should be between -2 & +2 degree F. The set temperature also depends on how full the freezer is. There will be a time when the freezer like refrigerators will shut down. This is relative to the term, "Frost Free". The unit will shut down for about 10 minutes. This occurs ever 8-10 hours. The heater turns on to defrost your freezer coil. It sounds like you are in good shape.

Car runs great until it get about 180 degrees andthen shuts off let it cool off a lil bit its starts back up until it shuts off again why


I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.

Main remote control is not working can you bypass the remote temporarily


No. However you may be able reset the thermostat to its factory setting.
Turn the thermostat off.
Shut of the gas and water supply to the unit.
Unplug or disconnect the unit from its electrical power source. Disconnect the thermostat from the heater.
Wait approximately 5 to minutes, and then reattach the thermostat wires to the heater.
Turn the water supply on and open the tub faucet to its hottest setting for about a minute.
Turn the faucet off and make sure no water water is flowing anywhere in the house.
Turn the gas supply back on.
Reconnect the thermostat wires to the heater.
Connect or turn the power supply back on.
Wait at least 2 minutes before turning the thermostat power button back on.
After the thermostat power button has be pressed, wait an additional 2 minutes before running water.
Test the heater at this time. Turn the water on at the farthest faucet to its hottest setting. measure the temperature with a cooking thermometer.
If you need to make adjustments to the water temperature, either up down, shut all the faucets off first.
The thermostat should read 100 degrees Fahrenheit when it first starts.
If you are receiving an error massage, consult with the manufacturer.
If the thermostat is reading the correct water temperature but the unit is not operating, there are other issue need to deal with. Let us know if this works or you need further assistance.

"High camera temperature"


this worked for me: just hit the bottom hard with your palm and the top and sides, not the front or back. After 3 hits, the date screen came back on and it was fixed. This was after the other two solutions I found on this site failed, namely pushing the shutter down before the message comes on or blowing into the camera slot with the memory card removed.
