Hi all, this question may have already been addressed but I have been unable to find anything directly answering it.
We have just bought a Palsonic 12v/240v LCD TV/DVD 19" to be used at
home, in the caravan and occasionally the boat. We were told there was a special cable for connecting to the 12v battery system directly - but the
shop didn't have that cable and suggetsed Dick Smiths or Jeycars.
My question is this: should this be a straight connection to the 12v system or should there be something (a regulator?) which ensures a steady 12v supply (given that a fully charged battery may supply more than 12v).
If I need more than just a cable (and fused connector) what and where might I buy this item?
Thank you.

I would exercise a little caution.
A quick Google indicates this TV is a native 12V device which uses a 240VAC to 12VDC plug pack and Palsonic specify a specific optional part (DC1720 or something like that?) for direct operation from 12V.
There is no simple way of knowing how effective the power supply within the TV is at reject spikes and other electrical nasties and it may
well be the DC1720 has noise suppression components built into it - indeed it may even be an independent switched mode power supply. otoh it may simply be a piece of cable and a couple of plugs?
If you choose to make your own cable I _strongly_ suggest that when the TV is plugged into a 12V system (NB. not turned on merely plugged into) you do not start or stop the engine or switch on or off any items which use significant current ie. central locking, lights etc.
Having spent that much on the TV I suggest you buy the Palsonic 12V unit and read the instructions which accompany it.
