Sony bravia 189 watt tv.

Hi I recently posted before about a job where the local TV installers had cut the moulded plugs off dvd player,sky box,sound bar,and Sony bravia 2012 55 inch TV and stuck them all into a flex outlet behind tv and switched it from a 13 amp switch fuse spur .I've split them all up now so there all independently fused.the tv is from 2012 but not plasma ,the manufacturer states a 10 amp fuse for tv but I only had a 5 ,tried both wholesalers close by and of course they just keep the basics.went home to see if I could pinch one from my own house but all my tvs are 5 amp including the 55 inch which is rated the same.its a 1.00 flex .do tvs really have a large inrush current when switched on .does a 10 amp fuse really protect a 1.00 flex. Obviously I'll get a fuse online but If I leave the 5 amp over weekend I'd be worried it popped and caused damage .any advice welcome .it's a Sony bravia lcd tv kdl 55hx853 rated at 158 watt

CRT TVs had a considerable inrush current from the degaussing coils demagnetising the shadow mask, but that's all ancient history now. No significant inrush on a flat TV that I'm aware of.
I suspect that it's something that got lost in translation somewhere, and it's actually the maximum fusing, rather than the minimum, since most Sony TVs in the European area will be plugged in to the mains using an unfused plug into a socket supplied by a 10A MCB.

Thank you very much .do you think the 5 amp will be fine ,there's no heat coming from tv ive text the customer .I know the old plasmas used to heat up .a 10 amp fuse would run a washing machine probably indefinitely, plus its border line for flex.i did read that Sony tend to over rate there fuses as standard .

Ì'd be very surprised if a 3A fuse ever gave problems.

Yeh I know I'm 99 percent confident that there would never be an issue but its the customer that's causing me to stress ,he thinks his tv might blow up lol .its not the work that's stressful but people .thanks for your help

189 / 230 is 0.82A

Even if the inrush was 10x…. That’s stil 8.2…..but only for a fraction of a second.


13 years for a TV is pretty good going these days.

Fuse popping, is not fundamentally different as far as the tv is concerned to switching off the spur.

Anyway, isn’t that what a 6mm screw is for

Yeh there would be an internal fuse any way.prob rated at 6 amps lol.no I would imagine it would be an a amp or so.it was just the customer was doing my head in when he checked and saw it should be a 10 amp as per manufacturers. You can't get 10 amp fuses off the shelf ,not near me anyway

Yeh it is still looks in good shape to but heavy ,16kg compared to mine which is like a square Frisby. The customers very attached to it .the fact it was that heavy brought a little doubt in my head

You are overthinking this 5A is fine.

I know this is meant as a joke, but it alludes to what I'm on about in my first post. All 'fusing' for the actual TV will be internal, in the form of electronic overload protection, special fusible resistors and maybe the odd glass fuse. The TVs are produced for multiple markets, and the only destination where the enclosed mains lead will have an internal fuse is the UK. It's there solely to protect the lead, since all other fusing s internal to the TV, provided the maximum external fusing is 10A.
You say the manufacturer's instructions say a 10A fuse in the plug. This will only be in the English instructions. If you have the usual multilingual instructions that you get these days (the inch thick booklet, where only ten pages are relevant), then it would be interesting to point Google translate at one of the other languages and see what that says.
