[Simply Computers] Re: Can computer destroy monitors?

 

Computers cannot kill monitors as far as I know.

The voltage coming out of the computer is way too small to do any damage to the monitor.

However, you may have a different problem with that computer.

You took the one monitor to BestBuy and they hooked it up to a different computer and it worked, therefore it was not dead.

What you saw on the screen was probably a diagnostic program they ran.

But the fact that the monitor displayed anything other than just a black screen proves the monitor was not dead.

Your computer feeds the video signal to the monitor through the video card / chip in the computer. If the monitor goes black, it could be a fault of the video chip, or even the connecting cable.

The way we test it is to hook the monitor to another computer (as Best Buy did), and if it works then the monitor is good.

We also would hook a known good monitor to your computer. If it works, then the computer is also good, and the problem might be intermittent, or caused by something you're overlooking (like a screen saver)

In your case, I would hook up the monitor that you got back from Best Buy to the computer and see what happens.

let us know

ps ... one thing that can kill monitors (and computers) is power line spikes ... you may need some kind of power conditioning device.

When it broke, I switched it out with another one from a very old Compaq computer we had and are using to occasionally write letters, etc (off-line work and not used very much). That only lasted less than a month, when it broke. I recently took the one that worked for about 2 years in to Best Buy and when they hooked up a laptop to it, it showed three color blocks (very sharp) and a message that something is not adjusted correctly. When it was hooked up to a desktop, it was just black. One thing - I do very infrequently (perhaps 2-4 times a month) watch TV programs using the computer. Could that have killed the CRT monitors?
