Techwood 16inch Tv Dvd Combo - £99 In Morrisons Need A 12v Cigar Lead

Recommended Posts

hi guys, i just went into morrisons and they have a 12v led 16inch hd tv/freeview/dvd combi for £99 quid. its 20w 3A 12v power adapter. i must say i was quick on the "i'll take one of those" response.

 

this was in stratford upon avon btw if anybody is interested.

 

now. .. heres my problem. i cannot find a 12v lead for it online (maybe im not looking properly) but can anybody please help me here

 

it is a techwood 16911hd led dvd model.

 

ac adapter is model number wa-36a12k

12v 3a output

 

its got a round plug with four pins on it (looks like a tesco technika connector) but just need to confirm.

 

thanks a million.

Hi Wayne,

 

You could try searching 'RS Components', 'Maplins' and 'Farnell' on line, but it may well be a special bespoke connector for that brand of TV, in which case you could try looking here. They don't actually show the lead that you are after, but there is a yellow box half way down the page where you can enquire about a particular spare part. Good luck!

 

Regards,

David :D

hello, i think you mite need a 12 volt to 12 volt stabiliser, because a 12 volt battery can peak at 14. 8 volts, a couple of friends of mine have blown there tv's because of this. some thing like this http://www. ebay. co. uk/itm/Amperor-12-Volt-LCD-TV-Stabiliser-DC-Supply-3-Adapter-/260661314977?pt=LH_DefaultDomain_3&hash=item3cb0a005a1, one of the three connectors mite fit your tv, hope this helps

Hi Wayne

 

If you get a made up lead, just careful as there are different ways of wiring the plugs, I have had two TV of different makes and the pin outs are different.

 

when I had the same problem a few years ago I blagged one from a company who sells tv's with that type of plug, and they sent on FOC and it was still

attached to a PSU so I cut off the lead, and attached a cig lighter plug.

 

And there is no need for a stabilizer as the other poster has said, the battery is stable, it cannot go up in voltage ! it will only go down !! and you are going to use it with the mains adaptor when the caravan is on EHU aren't you ! and use the 12 lead when just running off the battery.

Hi Paul,

 

Unless the caravan has a 'smart / multistage' charger, the 12v. sockets in the caravan will be fed from the PSU/leisure battery, and even assuming that the battery is in perfect condition and is 100% charged, the maximum on-load voltage will be 13. 8v. (EU regulations). Over the years I have run several different TVs direct from the 12v. caravan sockets, and it has not had any ill effects on any of them. :o.

 

Running the TV from the 12v. caravan sockets whilst on EHU and without a leisure battery installed in the caravan MAY cause some harm, as there will probably be a certain amount of 50Hz. 'ripple' in the 12v. supply from the PSU.

 

Regards,

David :D

If its like the attached picture, its a 4 pin tv TFT lcd adaptor which if you search on Ebay you will find a couple,

As far as using the caravan 12v supply, I have been using A LCD TV on mine for 3-4 years with no problems

ok so this wont matter since my multistage charger wont be connected when 12v lead being used (as if im on EHU i will milk it for everything from lighting to cooking to tv and playstation at night

it is like the one posted. yes not certain on the pin assignments * gets tv manual out. ..*ooo user manual "step three: insert plug into mains socket. step 4: switch socket on" could of been step three: insert plug and switch it on (unless you like everyone and leaves the switch on all the time )

 

ok my pin assignment:

@ - the notch (forget the word for it now lol. .. locator. .. whatever. .. at top of plug. ..

V+ * * V +

V- * * V -

 

so top two are positive bottom two negative. ..

and as for the blagging. .. i did consider the "my tv didnt come with a psu" line, but i think the mrs would take a dim view if i did that :P - and if it is possible to find i'ld rather not ;) lol. - plus i'ld probally wire it in reverse polarity like an egit lol. ..

 

=====

additional

just visited ebay. .. item number 330543334332 £3. 99. so with some 2 core flex, and a lighter plug for about 2 quid, my lead will cost about hmmm. .. er (3. 99 plus 2 is 5. 99 : P (we all have that nice bit of wire lying around dont we ; ) lol) orange wire mind. ..

 

now recommendation: stick with a 5a fuse on the socket. .. or shalll i add a 3a fuse into the cig lighter plug. . can i get 3a fuse cig plugs. .. : P

Hi Wayne

 

Just to confuse you ! I have a Avtex TV and the pinouts are, the four pins are +ve and the outer ring is -Ve so plugging in the wrong TV will blow

the fuse at least

 

as I said in my first post I have a lead wired the way you have stated on here, but I think you will also find that your wired ones have the outer

ring wired to -ve as well

it comes in pieces. .. lol arrived today. so ill solder tomorrow. .. one wire split arross two pins (5a rating) or did you piggy back one to the other? i haven't purchased the cig end as i actually decided to take the caravan plug off my inverter and use that instead (leaving my 6a cig socket free for my mobile in emergencies and also my laptop - when on a free wifi site) - i have wired a 13a 240v socket up by my tv bracket though . .. wasnt one there because didnt plan to use it but when im at home i have got a nice little "hide out" now :P lol. (well a nicer smelling one then my shed that is)

ill leave it as two + and two - because the diagram doesnt state the outer ring has a connection. .. but if it doesnt work. ill try that. ..

 

i popped into broad lane leisure today, the cheapest 12v tv they have is 350 quid. .. i asked em why they were so much "oh its specialist caravan equipment" my reply was "oh so why does my 99 quid tele from morrisons work on 12v then. .. - he just shut up lol. ..

 

- an idea for people is also: get a old pc flat screen monitor and get a vga converter box :) but as with the inverter = extra power :P

I bought one of these 6 months ago. The picture is great but - the viewing angles are very narow whcih can result in having to tilt / pack under the stand, other than that for £99 you cant really complain.

 

For the lead I got a ready made one of this fella on Ebay.

 

http://shop. ebay. co. uk/cra1g5tuart/m. html?_nkw=&_armrs=1&_from=&_ipg=&_trksid=p3686

 

Which works fine - just a word of advise dont use an Avtex 12 volt lead as they are wired differently - fortunatly I only blew the fuse in the lighter socket and did not damage the telly!

I did warn you huh.gif just used a twin cable and bridged one wire across both -ve pins, and did the same for the +ve pins with the other wire. A bit tight in the plug body to make sure no shorts, and a bit of a fiddle to get it all together correctly as per drawing !

I didn't connect the outer ring, and it didn't need it

i will have mine mounted on top lockers on a tilt / swivel bracket. (already in place :P) - therefore no light problems off windows and can watch in bed :D

well looked closely today, although i didnt get chance to solder (the solder i bought has grew legs and wondered - :P) i have concluded that a nice little dollop of solder should so the trick to bridge - so connect to left n solder onto both . it is going to be tight in the plug though. i am considering cutting some of the 18v 3a AC-DC adapters ive got in the shed down to use the wire off em ;)

 

is there a reason a caravan 12v plug (not socket - the actual plug) doesnt have a fuse>? (cigar's do, and so do 230v. so why not caravan plugs - or have i just got a cheap china special plug)

The fuse for the 12v socket(s) is fused on the caravan's fuseboard, usually 10Amp, you could put a lower rated fuse in as long as your sure you don't need higher ampage on the socket(s) at some time.

I think all 12v plugs are unfused, at least I've never seen any that are.

ahh cool. :P it just made me wonder considering car cig sockets are fused and their plugs that go into them :P mind the car socket is a 20a fuse and most items in the car are 5v = 0. 5a (as a usb port is) etc (phone, ipod, etc)

 

considering my socket for cig can only handle 6a. .. a 7. 5 fuse in the holder. should be cool for the tv, correct? or should i add a 3a (or simular) since the tv consumes 1. 73a.

Assuming you are using the caravan 12v socket for your TV (be it a 2pin or a ciggy socket) it will already be fused on the c'van fuseboard, you can possibly put a 5A blade type in place of the existing (the lowest rated fuse in this type, I think) as I previously said.

Or you could put an inline fuse in the power lead with a smaller rated glass fuse, ie 2A

OK Cheers. i to protect the TV as much as, so imma wire the inline 2a (i didnt realise i could get a 2a :D - i knew about 1a and 5a) . .. for the sake of a couple of quid its not worth mucking about. so i will either get a fused cig plug to use, or use the inline type as pictured. cheers. that way i will still be able to use the laptop charger in the cig plug too when need be.

you can get 1A, 1. 5A, 1. 6A, 2A, 3A, 5A, and so on in glass fuses, make sure you get to suit holder, there are so many sizes eg mini/20mm/32mm so best to get holder and fuse from same place

Due to being model specific on my DAB I cut the low voltage lead in half, got two small plugs and one socket from Maplin, fitted the socket to the cut off tail and the plugs to the remaining lead of the PSU and a lead for the caravan 12v

if the wiring kit never come with the TV, were I could just open the box and plug it into either the 3 pin or the cig lighter,I would just take it back, I am not a qualified electrician so dont mess with anything like that,your family is all sleeping within 10 feet of the tv & would you sleep easy thinking you have wired it correctly

wouldn't even bother in my book,

always unplug the tv overnight.

when running on12 volt, use a ross 12v to 12v voltage reg, the one with various voltages.

although tv says 2. 2 amp usage it works well.

Hi Gang, just to put my 2 penn'orth in. If you go on Flea-bay and type in 19" 12 volt t. v. Kogan. you will find a new range of T. V. DVD. Freeview combo t. vs. some are up for auction and seem to be going around £100 plus £15. 50 P&P or you can go to their website and buy direct at £129 plus £14 P&P. They are new to this country but not to Australia apparently. They also have a built in PVR which works with a memory stick. I am thinking about getting one anyway. If anyone out there already has one, will they please post their reaction? Cheers Peter. :rolleyes:

hmmm. .. does this mean if the fuse goes on your tv you'd buy another? or if you stood on the power cord and broke a pin? . ..

 

i've done plenty of electrical work in and around my home, never worried about any of it before. a 12v tv wire is one of the last things i would worry about. HOWEVER. I always unplug all electrics when not using them and even turn off my battery switch when i leave.

Hi Wassy

 

If you go to my earlier post (11 i think) there is a link to a fella on Ebay who sells them. Just tell him its for a techwood telly and he will send the right one. We have been using one for about 6 months without any bother and it leaves the 240 v socket for the missus to plug her light inwink.gif
