Will a 18v adaptor work for 16.5v tv?

Hi guys.

I just bought a Sony 20inch LCD with a view to hanging it on the wall in my kitchen. It was meant to go just above a power socket and coaxial socket which I had plumbed in. The point was so you would only see these two wires going up from the sockets to the tv.

Anyway when I opened the box I realised that the power cable has a big power adaptor half way through its length! This means this big black box would be hanging on the wall:thumbsdow

Anyway ED said the solution was to buy an adaptor plug to get around this. So I went down to Maplins and found they only sell either 12v or 18v adaptor plugs. Will a 18v adaptor be safe for a TV that is rated as 16.5v?

Many thanks

I'm sure it will work, but can't say for how long!

I wouldn't do it - think you might end up frying one of the circuit boards or some other disaster - can't see the warranty remaining valid either.

Why not just lengthen the cable supplied with the TV after the adapter, so you can hide the power adapter out of sight then just route a relativily thin wire to the TV?

Thats what I thought (ie frying time!)

Problem is there is nowhere to hide it really. If I stick it behind the TV, it will overheat it.

There must be a solution to this problem:(

Not adviseable 18V? 17Vor17.5V is poss but also depends on the AMP's too.
You could try to ask your local repair shop to order you an Equivalent or universal powersupply adaptor.They are around ₤35 and have different voltage and connector settings.:cool:
Ask your local repair man to extend the cable on your original powersupply.
GoodLuck!

Thanks, I found a universal one with different settings but it jumped in whole volts not halves so would have to risk 17V.

If I extended the original powersupply it still means I'd have the big black box somewhere(ie not held at the plug) and there is nowhere for it to go/be hidden.

Dont extend the 240v side extend the 16.5 v side then the transformer (black box) can simply sit on the worktop by the side of the socket outlet.

Its not ideal but not too bad surely?

The 17v adaptor option will probably work but why risk it.....if you do try make sure the polarity is set correctly or it WILL cause trouble!!!!!!!!

Steve, there is no work surface on that wall for the box to sit on! Its just a plain blank wall. Thats the problem you see, the box would just be dangling in mid air!

Any other suggestions guys?

To be safe, why not see if it works ok on the 16 volt setting of the power adaptor ?

I find that these step down transformers read slightly higher than rated. If you have a tester measure the output from the sony power supply

Hi Again Indus
there is some good advice on here and I agree with it all,but without seeing the site its impossible to advise much more.

However I am going to assume you dont have a meter to check outputs therefore if you try the adaptor do make sure the polarity is correct.

Going right back to basics cant you just return it and explain the problem and get something else?

Also if you could sit the transformer behind the TV I DONT think it will overheat.........maybe not ideal but I would rather risk that than risk anothe transformer.

Russ: I don't have a tester.

Chris: I'll have to buy the variable adaptor and if it doesn't work out I'm £20+ out of pocket

Steve, I will post a pic tommorrow morning. I could return it but the salesguy reckons 'most' lcds of that size come with an adaptor

Many thanks to all those trying to help:thumbsup:

There are PLENTY of 20" TVs that dont use a seperate transformer ie my Humax for one.

The way to go is return it and stop all the problems the easy way.

Thats right! :smashin: STOP messing around... by now any body with a bit of DIY knowledge would have sorted it out! (don't forget your Quote:"I had plumbed in") :D
You could have extened the p/supply o/p side cable with correct polarity, stripped the wall cable in put cover on to protect the cable on goes filler wait to dry rub down clean finish and paint.
spares available from any DIY Store.
kettle on. :devil:

When I said 'plumbed in' I meant I had it done by a professional sparky. I've just spent a very large amount of money on that kitchen including paying a professional decorator and all the walls skimmed. I'm not going to start stripping into the wall now!

I'll give the TV back, seems to be the easiest way. Its just a shame because for £230 it was a really nice tv with a great picture.:(

But it's "SHAME" you did not think of that before? :D
But there again what are we here for? To Give You Good Advice!:devil:

why not box in your plug outlet with a bit of painted mdf, but make the box a little bit wider to house your supply as well. might need to hinge the front for access. run a pvc conduit from the box to the u/s of your tv to hide the cable as well if you want.

Ficko, thanks. Thats a very good idea.:thumbsup: Once painted it shouldn't spoil the design/look of the kitchen.

Thanks for the advice mate.:)
