My 2 week cruise is imminent and the TV has packed up which we only use for movies. Can anyone recommend a 21-24tv with DVD player that can run off 12v? Ideally one with a decent screen that can be seem from a broad viewing angle.

I've always just bought one from Currys that are designed with an external power supply, problem is without going to the store I cannot tell which ones these are - very busy to get down there at the moment.

Any recommendations appreciated.
 
I bought a 12v Cello 15.6" off ebay for £129. Primarily as a monitor for an OpenCPN plotter, but it's a TV / DVD combo. The sound isn't great but acceptable (I plug it into an external speaker if decent sound is needed), & it has been very good so far. Also gets freeview radio stations. It is advertised as drawing 1.1A, but when checked (just as a TV - DVD not running) draws 800mA. Horizontal range of viewing angle is OK, vertical needs slightly more adjustment, but that's sitting at the chart table close to the screen. Slightly off topic but the 12v power regulator can supply 5A, so that also feeds power to the 12v brix PC.

Popular opinion seems to suggest that the Avtex is better, but they cost more. You pays yer money .....

Most small LG TV's are 12v with power bricks. A lot of Samsung TV's are 14v. I have a 24" Samsung (14v) running from a DC-DC convertor. Excellent picture quality, sound not bad, but i also have a Samsung soundbar, again 14v running from a DC-DC convertor.

If you are looking for specific model numbers, try Googling for a LG 240v to 12v power adapter, that'll tell you which models it's for. Do the same for Samsung.

I went round that loop but asking the staff was met with open jaws and blank stares. I found only one.

Cello has mixed reviews but you do get a lot for your money. The sound, however, is abysmal.

Any recommendations appreciated.

Genius idea thanking you!
 
I would be wary of buying a 240v TV that uses an external 12v power supply. On the basis that you can substitute ships 12v supply in lieu of TV supplied power supply. These power supplies (called brick or transformer) all now days use a switch mode power supply from 240v AC. This is inherently very good regulation ie 12v +or -.1 volt regardless of load. So the circuits are (may be) set up in the TV for this precise voltage. Your 11v to 14.5v ships supply could cause havoc.
I would suggest a safer bet would be a TV designed and claimed suitable for 12v battery supply perhaps from a camping caravan shop. Unless you fit a regulated 12v supply ie buck/boost from ships battery. olewill
 
Firstly plenty of 12v TV options on Ebay which is where I'm planning on getting mine!!!

Secondly rather than looking for a DVD player look for a TV with USB Playback, buy an USB stick and watch all of your films TV shows etc via that. Get most of my stuff from sky torrents but you can rip your own DVD's to your computer and just add to a USB stick as and when needed
 
I bought an avtex 12v TV about a year ago and I am very pleased with it. Good picture and the sound is not too bad. I also have a Chromecast plugged in to watch online stuff via mobile phone. It also has a feature where you can use a memory stick as a personal video recorder which is useful.

It replaced a Kogan? 12v which could not get a signal whenever the led lights were on. The avtex does not suffer from this. I assume that the higher price of the avtex results in better quality components that can filter out any interference.

This is why i use a DC-DC converter Will. By doing so it also allowed me to choose from a wider range of TVs, including Samsung 14v ones. I have a very nice quality 24" LED TV that cost about £150
 
We bought a Linsar LED TV DVD from John Lewis. Has 5 year guarantee and is 12v so none of this nonsense with 240v adaptor.

Picture quality is excellent from a very wide range of viewing angles. Sound is good, too.

I did a fair amount of research and, for my needs, nothing else came close to the spec nor the value for money.

I have a laptop onboard, tethered to my phone, tucked away in the chart table and connected to the TV via a HDMI cable. It's controlled by a small wireless keyboard and mouse. The TV is connected to a soundbar via a digital cable. All three run from the boat batteries via DC-DC converters. The TV and soundbar are fixed to the forward bulkhead.

The TV can then be used as a normal TV and the soundbar provides quality sound, as well as music via my phone and the Radioplayer app'. I can watch DVDs, downloaded films or TV series, all of the iPlayers etc or live TV. I can surf the 'net or check email on the 24" screen.

The laptop has OpenCPN installed on it and gets all of the onboard N2K data (GPS, depth, AIS etc) via wifi and this is also displayed on the TV screen.

That is interesting. I have noticed that our radio reception is swamped with noise with the led lights on. Do they have switching mechanisms inside? Would a ferrite slug fix it?

I tried load of things to try and get rid of the interference that was caused by the leds. I knew that the interference was airborne rather than being transmitted through the power cables as the Kogan TV had both 12v and 240v power supplies and it made no difference which I used.
I tried replacing the coax cable with better quality stuff with better shielding, various inline coax filters, and loads of ferrite clips - none of which made any difference.

I finally took a 240v tv from home to test and this worked fine with all the lights on so my conclusion was that the Kogan TV was very sensitive to interference so I replaced it with the Avtex.

Its well reported that leds produce airborne interference and I think that some are better than others, I am not sure if there is a 100% way to block this getting into AV equipment other that switching them off!
 
I bought a 20" Finlux for use as an on-board monitor but the picture quality is just not up to it. Little better for TV and in any case it doesn't receive HD channels. So not much use really for on-board ... ...

Your experience just reflects the difficulties and vagaries of interference suppression. I would not have suggested trying a different TV but clearly it was the answer for you. Yes some TVs design will have better selectivity in tuning in to just the TV signal and rejecting other interference. The text book approach to interference from switch mode power supplies which includes some LED current controllers is to use the ferrite bead for added inductance in the supply wires to both the LED fitting and the TV or radio. Along with the added inductance you bypass with capacitors to ground. The interference can be radiated by the power wire into the ether hence to the antenna as well as actually via the wiring. The next step is to fit a (faraday) shield of conductive metal around the LED fitting which is connected to negative or earth. If all else fails you might need to go to a magnetic shield ie iron that soaks up and bypasses any magnetic field from transformers.
Capacitor bypassing of power wires is not simple as a large capacitor exhibits inherent inductance so you use large C and small short lead ceramic C in parallel. Or you go to the extreme of a feed through capacitor which is mounted in the shield with the feed of power going in one side and out the other with low inductance so good bypassing. good luck olewill
