Why is my CRT TV blowing the fuse?

pastmybest

I moved into a new house a few days ago and now realise whenever we switch on our CRT TV it is blowing the fuse. Could it be the surge needed to turn on this type of TV or could it be something else.

The TV is about two years old and working perfectly well so I am very reluctant to get rid of it in favour of something more modern.

Help please if anyone can?

Tried plugging into another socket?

Do you mean that on switch-on it is tripping the Miniature Circuit Breaker in the Consumer Unit, or blowing the 5A (surely not 13A?) cartridge fuse in the three-pin plug?

If it's the former, then you might be able to get an electrician to replace the relevant MCB with one with slower trip characteristics.

If the latter, I would be rather worried. You could try putting a 13A fuse in the plug, but this shouldn't be necessary.

Sounds strange. As above, try plugging it into another socket - directly into the wall if possible. The only other things I would suggest are, 1. is the correct type of fuse fitted, and 2. can you try it in another house - maybe it got damaged when you moved?

A CRT TV would normally have a 13A fuse in the plug surely?

No it would not and a 13A fuse should definitely not be fitted!

What wattage is your TV?

Mine is quoted as approx 155W. According to the user manual: "In the UK, the fuse fitted in this plug is 13A, and is approved by ASTA or BSI to BS1362. It should only be replaced by a correctly rated and approved type and the fuse cover must be refitted".

Don't forget that there is a current surge when you switch on a CRT TV, so you can't simply use W=VI.

Sorry, I think that should read "WAS working perfectly until we moved it" ..... maybe.

As previous have said, try it in another socket, try other appliances with a similar power rating in the socket that keeps causing the blow when you switch the TV on.

If another previously-good appliance also causes a blow, that would suggest the socket wiring is suspect. If the other appliance works fine, that suggests the TV has been damaged in the move.....

The other thing to look at is if your old home did not have circuits with RCD protection (yes menay still stupidly don't have them) and your new one does. If this is so then it may be due to either a fault in the wiring to the TV or it may have an earth fault on the TV. If this is correct then in both cases your electical safety circuits are working correctly and you need to sort the TV out.

Thanks all for the very useful replies.

So far it seems to happen when the TV has been switched off for a longish period particularly overnight.

It is a 28" Philips which says 65 watts on the rear of the TV.

It is plugged directly in the socket and not an extension cable.

The fuse in the plug that was fitted when we bought the TV is 13 amp.

My old electrics were fully refurbished slightly before the TV was bought. My current electrics are 16/18 years old and it is the individual fuse carrier called "ground floor sockets" that goes and all other electrics are still working.

I will take off the socket plate to see if there is any obvious problem with the wiring.

I will try other things in that socket with a high load.

P.S. Does anyone think my wife is sabotaging the TV as she wants a new 40" flat screen
