Quote "The electronics in LCD TV's (and similarly laptops) need several
different internal rail voltages, so the 12v input will receive further
voltage changing and regulation inside the set."

Simple answer please Harry "Would you run a domestic TV marked DC in (12V)
from the gel battery on your caravan whilst the mains were connected
charging the battery?" Yes / No would suffice with perhaps easy to
understand additional equipment
if req. Thanks

YES

Is I have done it for years simple enough for you!
Probably not

I understand ok - thank you - but then I would be disregarding advice from other contributors and something tells me it could not be that simple -

that's just is, i doubt more than 2 people on here own a lcd tv of the same make, the names change almost daily as the chinese copy more big name brands, substituting parts for lower quality ones to get the price down.

yes, 'some' tv's may be able to handle the voltage fluctuations, spikes, harmonics, noise, switching transients and so on from being run directly off a battery, but a lot of them won't, and a few years ago lots of people were finding that out.

Ask the manufacturer if your not sure, but i doubt they will give you the go ahead to use it on a different power source than they designed it for.

the OP asked if it was ok to run his TV directly off the batteries, the 'safe' answer is no, use a dc-dc psu instead (just a thought, when the OP says the psu gets very hot, you are running it on shore power? and not an inverters output? as a non pure sine wave inverter will make psu's run very hot)

of course the advice the OP takes is worth exactly what he's paid for it, i.e. naff all, so if the TV blows it's backlight inverter, he can shout and moan at the people who said 'mine has never failed so yours wont' but he cant get them to pay for a new TV for him.




Take NO as the answer to my original question .......and today I have bought a 12v 12v DC stabaliser. Now to get the soldering iron out. Maplins etc etc do not stock them bought of the net.
