Hello there
You dont say which machine you have but a common problem is they are set for the WRONG input,
Have you checked using the 'onscreen' menu,of the monitor that you are looking at the right INPUT ???? D-sub is the 15 pin video cable input from your computer to the monitor. .It will go dark if you are not supplying a signal on that input.

You didn't mention what make and model you have - but this seems to be a graphics card issue. Many (HP laptops a few years ago in particular) developed "Cold" solder joints on the motherboard at the graphics card. When the computer heats up, the connection is lost, when it cools back down, the connection resumes. Usually requires a professional repair - either by attempting to "reflow" the solder, or replacing the motherboard in its entirety. Might be more cost effective to consider replacing the computer.

Sounds to me as though the backlight has gone faulty on your screen. It will need to be repaired or replaced I am afraid.

Huh? D-Sub is a connector? If you plug an external monitor into it the laptop is probably designed to shut of the internal screen. If this is not what you mean please get someone who can write a functional English sentence to clarify your meaning.

It sounds like you have not selected the correct INPUT to the device.OR not connected the cable correcty to the input.

Check your user manual for the device.

the easiest thing to do is check the voltage at the amp, between the red power wire and the black it should be the same as the voltage across your battery under the hood. now turn your radio on and c heck the remote turn on wire this wire is at the amp and is usually blue it should have 12 volt when the radio is on and 0 volts whe the radio is turned off check between the blue remote wire and the black ground wire unhook subs from amp and check the resistance across the speaker terminals with a digital mutimeter, if your subs are 4 ohms then your reading on the meter should be around 4, if it is close to 1 or 0, then it's probibly your subs. if everything is good check the fuse on the amp

some parts inside your tv is damage or short circuited. too expensive to fix or replace

put someone else's simcard turn it on then off put your sim card in and turn it on that how i fixed mine
