Check the DC filter caps and the four transistors in the power supply/inverter board.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Displaying only 2 secs


Monitor STFC (Self Test Feature Check)
* Turn off the monitor
* Plug the monitor power cord directly into the wall socket to remove any surge protectors or APCs from the troubleshooting equation
* Unplug the monitor video cable from the back of the computer
* Turn on the monitor
* The floating dialog box should appear on screen against a black background. If the issue appears during the STFC, the monitor is defective. Get it replaced.

Dell monitor screen suddenly went white. Can it be fixed?


I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

Got an alpine cda 9855 the screen keeps goin black but if you touch the button it comes back on it has like a 5 sec delay then it goes black but still plays any help


Blackout Display Mode: When the Blackout mode is activated, the display turns off to reduce power consumption. The additional power made available by turning off the display helps enhance sound quality. If a button is pressed during the Blackout mode, the display will illuminate for 5 seconds before blacking out again. Blackout Mode On and Off (CDA-9855 only) When Blackout mode is turned on, the display will turn off to reduce power consumption. This additional power enhances the sound quality. Press and hold FUNC. for at least 2 seconds to activate the blackout mode. The display will turn off. If any button on the unit is pressed during the blackout mode, the function will be displayed for 5 seconds to show the operation before returning to Blackout mode. To cancel Blackout mode, press and hold FUNC. for at least 2 seconds.

My screen goes black after a few seconds


Sounds like a bad solder joint on the printed circuit board. Once it heats up then it no longer makes good contact and the monitor goes black until it cools down and makes contact again. You could resolder it if you knew where it was but monitors are dangerous to go playing around with as they can hold very high charges of electricity in their capacitors that are very dangerous. It's a throw away world. Go buy a new one.

Your power supply may not be supplying the required electricity to keep your monitor on. Try plugging your monitor in a different electricity source. Your CPU may be drawing much power from the source and not enough is supplied to the monitor. You may plug the monitor directly to the UPS (uninterrupted power supply) if the cable end allows it.

Check the cable connections on the back of the monitor and the PC it sounds like the connection isn't made properly make sure they are tight.
