hi can anyone confirm if a standard 19" lcd tv can be powerd in the van with 12v & a 12V Stabiliser for LCD TV's fitted inline or does it have to be a dedicated 12v tv? thinking of this 1 at a good price
CELLO DIGITAL 19" HD READY LCD TV WITH IPOD DOCK AND BUILT-IN DVD £225 comet
Just checking I understand your question. You want to know if a mains only TV can be powered off a 12V van supply with a 12V stabiliser in line?
If so, the answer's no. But depends on aspects of the spec not quoted.
That doesn't mean you can't use it of course, but motorhomers do tend to ask about a particular solution rather than their real underlying question, so maybe that's the case here.

don't know about that tv but I run a 17" phillips lcd straight from the 12v supply with no hassle.It did come with a 240v drop down transformer ( 12v dc output ) so I would run it via the invertor but then I thought why go from 12v up to 240v then back down to 12v.Works fine.
Curlyman,
The TV is made by Alco on China and will run using an invertr. However, this TV will not work with the new Nano without an upgrade. The tuner also has a frontend sensitivity issue, which means that if the digital signal is strong the tuner wll not tune all of the digital hannels. This will make it appear that the signal is too weak, but is actually the other way round. Currently the only solution fr this is via the service menu, which will require engineer intervention.

SIMPLE GUIDE TO 12 VOLT LCD TV FOR MOTORHOMES
LOTS OF TVS WORK OFF 12V---ASDA, TESCO, COMET, CURRYS ETC.
MAKE SURE IT SAYS 12V ON THE BACK
MAKE SURE IT HAS A PLUG TYPE AS IN PICTURE not four pin etc,
THESE PLUGS ARE READYLY AVILABABLE OFF GAMES CONSOLES ETC,
YOU CAN USE YOUR 240 LEAD ON HOOKUP OR MAKE UP A LEAD FOR 12V VIA CIG LIGHTER OR CROC CLIPS (PORTECT WITH IN LINE FUSE)
OR WIRE TO YOUR ARIEL PLUG
IDENTIFY POSS AND NEG THEN MAKE UP YOUR LEAD
IF YOU WANT TO YOU CAN PROTECT WITH A VOLTAGE STABILIZER
OR AS IN MY CASE JUST WIRED DIRECT TO ARIEL PLUG.
IF USING VOLTAGE STABILISER YOU MAY FIND THAT IF VOLTAGE DROPS TO 11.5V IT WILL NOT WORK, BUT IF NONE USED YOUR TV MAY WORK AS LOW AS 10.5 V (LONGER)
AS VOLTAGE DROPS THE PICTURE WILL GO OFF BUT STILL HAVE SOUND, SO PLENTY OF WARNING TO CHARGE YOUR BATTERY BEFORE ANY DAMAGE OCURS.
GASPODE - KEN sums it up simply--------
There are always conflicting opinions on whether it is safe to use a 12v TV directly from the van 12v supply. I see the argument this way:
Using an inverter from the van battery to provide 240v then powering the TV via the mains adapter is inefficient and uses considerably more power. I tested my current TV last week and there was a 25%+ difference in consumption. It is therefore better to use the 12v direct if possible.
The first point to make is how much did you pay for your TV? If it's a £350 super-duper model then perhaps it may be worth splashing out on a voltage regulator or going for the inverter option. If you paid £50 for your TV then why not just wire it straight into the 12v and risk it? In most cases the TV will be absolutely fine.
The second point is why not be versatile? The risk of the van battery voltage exceeding the safe input voltage of the TV only applies when the battery is being charged, ie: when the engine is running or when on hook-up with the charger powered up. So why not adopt the following strategy?
a) Don't use the TV when the van engine is running unless you use it via an inverter and mains adapter.
b) If you're on hook-up either use the TV via its mains adapter, straight from a 240v socket or turn off the battery charger when the TV is in use.
Seems perfectly simple and logical to me - and saves both cash and battery capacity.
