LCD TV turning itself off is not necessarily overheating.
Often, because of a faulty component, capacitors can accumulate electrostatic charge until an error is detected, or a fault condition can last for a while, until a problem is detected, and the protection circuit will force the TV to shutdown.
The only temp sensor that can shut down because of overheating is placed on the main board, and TV shutdown after a while is often not caused by overheating on LCDs.
Parts that often cause shutdown after a time are Power Supply Unit, Inverter, and main controller board. Parts must be tested to find the fault. The technician can follow the diagrams detailed on service manual to find the fault.
Regards.

Why does my EVE SC307 Studio speaker turn itself off right after I turn it on? How can I fix it?
There could be several reasons why your EVE SC307 Studio speaker is turning itself off shortly after turning on. Here are some possible reasons and troubleshooting steps:
  1. Power supply: Make sure that the power supply is securely connected to the speaker and the power outlet. Try unplugging the power cord and plugging it back in to ensure a secure connection.

  3. Faulty component: There may be a faulty component inside the speaker that is causing it to shut down. In this case, it may be best to contact the manufacturer or a qualified repair technician to diagnose and fix the issue.
  4. Firmware issue: Sometimes a firmware update can solve this kind of issue, check the manufacturer website and update the firmware.

My samsung home theater system it keeps on switching off i can say in 2minutes too5 sow i want to know what might be the problem?
Your home theater system has built in overheating protection. If it gets too hot, it will shut itself down to prevent itself from melting. If it is turning off without shutting itself down first, there could be an issue with the power supply from the wall outlet.

Why does my TV keep turning off while I'm trying to return it
There could be a number of reasons why your Alba TV is turning off after just a few seconds. Some common causes include:
  1. Power supply issues: If the power supply to the TV is not stable, it can cause the TV to turn off. Check if there are any loose connections or faulty cables.
  2. Overheating: If the TV is overheating, it can shut off to protect itself. Ensure that the vents and fan are clear of any obstructions and the TV is not in a location that is too hot.
  3. Faulty remote: Sometimes, a faulty remote can cause the TV to turn off by itself. Try removing the batteries from the remote and see if the issue persists.
  4. Faulty hardware: If the TV's hardware is faulty, it can cause the TV to turn off. This could be due to a number of reasons, such as a defective power supply or a malfunctioning circuit board.
If none of these solutions work, it's possible that the TV is defective and needs to be returned for a replacement or repair.

Picture keeps freezing
There is a few issues that can result in picture freezing
1: Overheating, keep it in a open area away from other devices
2: Your coax line from the cable company is going bad, if the rest of your TV's in your house are ok then its the one line itself going to that box, it could be an older 59 line or the fitting on the line needs to be changed.

Phone keeps switching itself off
Hello

OK, the fact that the phone keeps restarting or switching off, is either an overheating issue, or, most probably a firmware related error. You will be able to get the firmware updated at your nearest brand service centre.

If the firmware update does not work, it is an overheating error.

Feel free to let me know if you need any further assistance.

Kind regards
Andrea

TV cuts itself off
It may be overheating. Check the temperature with your hand by placing it over the fans/slots to feel for any excessive heat. If it won't turn back on until it cools, then it's a heat issue. You could help that out by using fans to circulate the air around the unit, trying to keep it cool by moving the hot air released from it and pulling in cooler air. Other than that, there may be a short somewhere, or maybe even a broken fan.

My playstation turns on then after a few minutes it turns of by itself
If the power button binks red after it shuts off it is over heating. Get some air duster and clean out the vents on all sides of the system. Make sure it has plenty of room to "breath" in your entertainment center. In some cases you may have to take it out of the entertainment center to keep the device as cool as possible.
