Hello all and after some recommendations for a 12V TV that can do the following but not cost the earth (therefore not Avtex):
12v and 240v switchable.
Relatively low power supply.
Good viewing angle (have a Cello TV at present and the viewing angle is not that great).
Ability to play movies from a HDD/USB stick.

Regards

why switchable, if its 12v you can run from batteries and just stick your charger on? might be a cheaper option.

some TVs (i.e. generic off the shelf TVs with DVD player and USB stick) have a transformer in them / on their plug and run 12v so you could always lop that off / take transformer out and wire accordingly. (if you know what your doing of course)

that's what I did, TV cost me £90 (sharp 24" LED HD) - no longer made so the model number is pointless for you, but plenty of others out there.
 
When I was looking around for a 12v 22 inch TV earlier this year I chose the Cello. Very good customer service, low power consumption etc.

The two downsides I found: The sound quality and as you mentioned the viewing angle. Horizontal seems fine but vertical is quite tight.

I struggled to find anything else that seemed to fit the bill for the money.
 
Many off the shelf LG TVs in boat sizes are 12v, powered by a 240v "brick".

Many off the shelf Samsung TVs in boat sizes are 14v, powered by a 240v "brick".

I both cases i would run them through a DC-DC converter for a nice stable supply.

Check individual models for features, but my 24" Samsung has a USB port, 2 x HMDI ports, optical digital out etc. I connect my laptop to the TV via an HDMI cable and the TV is connected to a Samsung soundbar (also 14v through a DC-DC converter) with the optical cable.

I get HD quality movies from the laptop, with almost surround sound quality sound. I can use the internet, check email and run navigation software etc on the laptop, with the output on the TV instead of the laptop screen. The laptop is controlled from a small wireless keyboard. I can also connect my phone to the soundbar, independent of the laptop and TV, and listen to any radio station in the country for free, with the Radio Player app'.

Note, when fitting DC-DC converters, connect them to a switch so you can turn them off, as they have a small current draw when not in use. I would not worry about running the TV from 240v, the battery charger should take care of that. It could be done though, with a changeover switch.

How thirsty is that set up? Does your dc to dc converter step up to 14v

Yes, the DC-DC converter steps up to 14v for the soundbar and TV, another one steps up to 19v for the laptop. They are all buck/boost, so maintain a stable voltage.

The soundbar uses 0.3a, whther it's just on or it's playing music from my phone via Bluetooth.

The phone uses 0.1a when it's plugged in, charging and playing music through the soundbar and providing the 4G data connection that i'm using to type this.

The TV uses 1.9a.

The laptop is fully charged, maintaining its charge and is currently engaged in my typing this , it is using 1.6a

So, running and maintaining the laptop charge, maintaining the phone charge and streaming music to the soundbar, providing 4G internet to the laptop/Tv screen and viewing it all on the TV is using 3.9a. If i only wanted the music on i can put the laptop to sleep and turn the TV DC-DC converter off, which then uses less than an amp.
 
Sounds good, was going for a cello or equivalent but I’d rather get a decent tv, have a raspberry pi with media player/games to fit for entertainment, being able to hook up a pc is a bonus

Do you have any more details ref the TV model and also what DC-DC converter?

TV is model LT24E310
Soundbar is HW-J250
DC-DC converter is one like this (the actual one was on Ebay, but i can't find it there), lots of these around, find the best price, be sure to check/set the output voltage. Been using two of these for 18 months and no problems : https://www.amazon.co.uk/LAOMAO-Converter-10-32V-12-35V-Adjustable/dp/B00HV43UOG

The TV sound is not at all bad, but the soundbar is really worth having. Not only is the sound better, you can use it on it's own, with your phone and have radio for very little power.

I take it one of these converters doesn’t have the output current capacity to supply both?

It should do, it's rated at 10a, but i prefer one for each appliance. You don't want to leave the DC-DC converter powered when you don't need it, so i have separate switches for the two converters. When i don't need the TV on i turn its converter off, same for the soundbar (although it would be rare to have the TV on without the soundbar). if i just want some music on i only turn the soundbar converter on.
 
I fit a good few of these aftermarket for people https://www.ebay.co.uk/itm/LG-29-TV...363859&hash=item4b4c298156:g:EAsAAOSwsI9aFUmr

Then if 12v supply is needed use an appropriate adaptor which we source from one of our electrical suppliers. Although something like this https://www.ebay.co.uk/itm/Netbook-...321191&hash=item41ec59adb1:g:jfsAAOSwYM9bjRDT would suit very well, although may require the end to be adapted.

29" tv on a boat was pretty much unheard of a few years ago! LG also make a slightly smaller version of the screen too, and of course bigger.


I'm running 2x 22" LG screens at the helm for charts and radar then have a 29" in the saloon and another 22" in the forward cabin. Only thing with having so many screens in a small space meant that the remote control was falsely triggering other TV's occasionally but this was dealt with by a piece of black tape.
