Sceptre monitor turning on and off
You should try these troubleshooting steps if your sceptre monitor turns on and off.
1. Overheating
When a monitor is overheating, the monitor goes off automatically to prevent any damage.
The main reason for overheating is excessive heat or dust, or vent blockage. Too much dust jams the vents, due to which heat cannot escape.
Another possible cause may be not balanced room temperature. You should turn on the fan or AC for the room in which you use your monitor to balance the room temperature.
If you face this problem, you should disconnect the monitor and allow it to keep cool for use again.
Before use, you should need to clean the vents properly with a vacuum cleaner. Once you clean the vents, turn on the monitor if it works.
2. Fix Loose cables
The common cause of why monitor turning on and off is a lose display cable. Sometimes the cables connected to the monitors are loose.
The same problem with the power cable or cord that connects the monitor to the socket is not connected well to the back of the monitor; it results in power loss, due to which your monitor turns off.
Sometimes, cables could be damaged with a twist or pinch due, which can cause a short circuit and your monitor screen to go black.
You should disconnect the cable from both ends, examine if the cable is free of any damage, and replug it securely and tightly. If the cable is damaged, you need to exchange it with a new one.
3. Malfunctioning Power Supply Unit
The loose connection of the power supply unit makes the monitor to not working at all. Sometimes dust on the PSU can cause the monitor to turn off.
You should clean the PSU and its fan, turn on the monitor, and check it. If it is not working, you should try with another PSU. Turn on the monitor and check if it works.
4. Check for Defective graphic card
A defective graphic cards can also cause the issue. You just need to remove the graphics card, turn on the monitor, and see if the problem is solved, so the graphics card is faulty.
Another issue you might face after turning on the monitor is a generic pnp monitor error which is caused by the graphic card.
You should need to update all the graphic card drivers and download and install all the new drives from the official sceptre monitor website.
After trying these steps, turn on the monitor if it works.
