Mikomi 15LCD250 15in LCD TV

[JohnI.Stephen]

Upon recommendation in this venerable forum (!) I purchased this Mikomi 15" TV from Argos a few months ago. It's really GOOD and I would highly recomnmend it for caravan use. However, whilst it runs off 12v, it only comes with a 230 --> 12v adapter; which is fine when hooked up to AC, but not so great on some CLs.

So, have any of you managed to find a 12v plug which fits this TV to enable you to plug directly into the 12v electrics of the caravan?

Wow, is it just me or has entering URLs into the PC forum suddenly got a blip ?? Take a look at my previous post and the URL is carzy and includes a URL to proactical caravan. This is what should have appeared in the link :-

I use a 15" Philips lcd for my caravan and have been pluging it into the caravans 12v socket. One small problem is that the 12v supply from the 'van is not a constant 12v and therefore can be slightly more than 12v, sometimes as much as 13 or 14v. The mains lead/adaptor is regulated to 12v. Therefore this resulted in knackering my tv and is now in for repair. One solution would be to fit a voltage regulator into the lead from the vans 12v socket.

There is a world of difference between 12V used by electronic equipment, usually regulated to an exact level, and 12V lead acid batteries which provide power anywhere between 10-15V.

My limited knowledge of electronics recalls that a 12V regulator would have to convert the battery voltage (10-15V) up to, say, 18V and then regulate it down to an exact 12V. This would have about the same efficiency as a 230V inverter, which would be cheaper and useful for other low power appliances.

Very interesting; well, since I already own a decent inverter, it seesm like I'd best stick wit running the TV from 230V and use it's supplied power lead.

Thanks for the advice; your expereince has convinced me Danny!

I bought one of these Mikomi 15 inch LCD tv's just over a year ago from argos, I got it because mainly of the good price. When i unwrapped it i found it had an adapter to reduce the voltage to 12 volts, so i cut of the lead from the adaptor to the tv and wired on a 12 volt plug as used in my caravan, we always use a hook up and have the charger / 12 volt supply switched on in the caravan, the tv has worked without fault for a year. After I first did it I read some comments somewhere that lcd tv should not be run from 12 volt batteries, however I decided that as i had already cut the lead, and that after all the tv did not cost a fortune that i would leave it and see how it lasted, so far so good.......

Hi John

I have used my Bush one(same tv different name) on only 12v for the last 3yrs,no problems at all,made a cable up with connector and a 12v end.

 

[JohnI.Stephen]

OK Mikey; that's interesting. From where would I source an extra 12v plug to fit the TV; it doesn't look standrad to me; but then it may be ?!

Thanks

John

Hi John

I was lucky enough to have a cable from some old modem psu's which had the dc power plug on already.All i did was put a cigarette lighter plug on the end and hey presto.My van has the cigarette 12v sockets,if you van doesnt then its the 2 blade type i would think.
