There is a suspected general failure of the monitor, which does not appear to have any
Explanation: The monitor appears not to be working at all. There are no indications

Diagnosis: Usually this is bad news, of course, though sometimes there is a simple
explanation for why a monitor would not have power.
- Make sure that the electrical outlet is working, by trying another appliance in the
socket and seeing if it works. If the socket does not work, you will need to consult an
electrician to have it fixed.
- Check any power protection devices that the monitor might be plugged into, to ensure

or surge. A fuse that blows more than once usually indicates some sort of problem either
with the device or the electrical circuit. At this point consulting a professional would

repairs of this type will often be successful, because the problem is likely to be a blown
component that can be replaced and not something serious like the CRT itself.
