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.

KDL52EX700 shuts down and restarts


If it is showing a blue scree of death (BSOD) and shuts down before you can read the error message try this:
Turn the computer off, then turn it on and immediately start hitting the F8 key repeatedly until you see SAFE MODE. Scroll down below Safe Mode and you will see an option to Disable Automatic Restart. Select it and reboot your machine. Next time it boots up you will be able to read the error message. You'll probably need a system disc or repair disc to fix the blue screen error message.

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.

My HTC HD 7 phone keeps turning off it goes to the white screen with green HTC then shuts off and keeps doing the same thing over and sometimes when i try to use it and i tap the screen then it shuts off...


I finally had to have them replace the unit. If doing a factory reset does not help, then I would have them replace it. Mine started rebooting infrequently, but then started doing it more often. They didn't waist any time getting my replacement out.
Please make sure you back up all your contacts/email before proceeding. I use Google on my phone through the Outlook option. Google/Outlook syncs all my mail, contacts, and calendar.
RESET: Software: SETTINGS > ABOUT > RESET YOUR PHONE
Hardware: 1) Turn off phone 2) While holding down both the Up/Down Volume buttons, turn unit on 3) Keep holding down the volume buttons until white screen appears 4) Press the Down Volume button to reset to factory defaults. 5) Restart phone

"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.

Need help with HT-z410


When your home theater's display reads PROTECTION, it means the home theater is over heating and the unit will shut down to prevent any damage. This can happen if the unit is stacked along with other electronic devices or the unit is in an enclosed area that prevents the unit from cooling properly. To decrease the chance of overheating, relocate your home theater to a more open area.




If the home theater display reads PROTECTION every time you turn it on, no matter where or how the unit is placed, it needs service. To set up service call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

The printer Board B1: you must shut it down by hitting the Options button and then selecting Function >Shut down > Shut down sytem>OK. Then power the machine off with the main switch.
