PC Monitor blows fuse when turned off.

Here's a good one.. My Dell monitor screen operates without any problems until it is turned off. When it is turned back on it won't start because the monitor fuse is blown. I replace the fuse and it works fine again. This happens every time. Any ideas?

Are you fitting the correct value fuse for the monitor.

Otherwise it is a bit of a mystery unless shutting down the monitor causes a transient power surge of some type.

It's more likely that the fuse is blowing at switch-on. Check the fuse as advised above. If it's OK then try a slow-blow (anti-surge) fuse of the same rating.

Hi VCR97 If that were the case the monitor would not work at all. If it is a mains fuse then you don't have a choice of type. They are all HRC (High Rupture Capacity).

If the fuse has recently started blowing, you should be investigating WHY.

Fuses are there for a reason. TO PROTECT YOU.

It's time to find out why. Possibly a Transformer, starting to break down. Whatever. Unless you can identify the cause and repair it. It's time to retire the Monitor for your family's safety.

That's true. Must engage brain before hitting keys.

Isn't that the reason for the post?

Yes, but we don't have access to the monitor. All we can do is offer theories. I have already offered one and will now offer another.

The switch is faulty

What happens if you simply pull the power supply lead out - don't switch it off, in other words - and then plug it back in again?

Almost regardless of the cause, cost of repair may exceed the value of the Screen.

However a replacement will cost.

How old is it? Do you have any proof of purchase/

If you do and it is less than 6 years old (5 in Scotland), get in touch with whoever you purchased it from. Unless it is very new, they will not refund you the full cost, they're allowed to deduct a %age for the use you have had out of it.

Maybe you can Upgrade to the one you have been eyeing in the adverts
