Damp TV (1 Viewer)

[Rapidorob]

Hi Everyone, I have searched Motorhome forums to help solve problems since we first got our MH some 9 years ago but only recently paid up to join. We have just returned from our first trip of the season to Hampshire and had a very enjoyable time.
But I have had a problem with our TV, a Kogan 16inch with DVD. The remote failed to operate and when I tested it with my smartphone camera was seen to operate. So the receiver in the set seems to be faulty. I'm trying to get the back off but having removed the screws it seems to be still firmly held in place. When handling it I find that it is damp and sticky, and with it stood on its side brown moisture is leaking out.
If I cant get the back off to repair it I don't think I can tune it from the set buttons and it may have to go but if the damp is going to damage a new set, then I need to solve this first.
Does anyone know why it should be attracting moisture? We do a bit of cooking but I don't understand why the moisture should condense on the caseing and insides of the TV.

It might assist if you let people know what van you have.

Does the TV slide down into a unit or just sit on a bracket on the wall etc.

I suspect the back of the TV has a security screw somewhere - usually under a sticker.

Hi MikeD, We have a Rapido 924F which has a cabinet for the TV with a rollback door. It was originally designed before LED flat TVs so I have installed a panel and fixed a sliding bracket support to it for the TV to be slid out and back into the cupboard when not in use.

Water dripping from above or running down the aerial lead?

 

[Northernraider]

Have you been by chance watching the bbc news?





I only ask because brown sticky liquid sounds a lot like excrement and watching BBC news there's a lot of that on there so perhaps it's overspilling in to your tv

Hi Alex, The aerial socket and power connexions are at the rear of the cabinet and the feed to them is not visible within the TV cabinet. The leads are not damp.
Thanks.

Oddly enough I had the same problem, again a Kogan TV with symptoms similar to yours, though not actually running. There was however a sort of coating of a sticky greasy substance. Our tv lives on a slide out bracket in a cupboard directly over the hob, and I suspect condensed steam and grease. Strange that the predecessor tv didn't have this problem (not Kogan). The TV has gone to the tip so cannot investigate further.

Sounds like a capacitor or on-board battery has maybe failed and leaked out ?

 

[Stealaway]

Yep a blown cap would seem like water. Hopefully it will be obvious and easily replaced.

 

[Rapidorob]

Hi Jockaneezer, Stealaway, I guess it could be a blown Capacitor but to find it damp all over the back of the TV and drpping out from inside, it would have to have been quite a spray of liquid! If I can get the back off maybe I will find out.
Thanks for the suggestion.

Agree with earlier posts it could have been caused by water finding its way down from above via the coaxial TV cable or a failed capacitor etc. Should that not be the case maybe the purchase of a cheap hygrometer such us in the link below placed in the cabinet housing your TV and checking the readings daily and if it reads wet - you may have a problem.

Any fluid leaking out an electric item I'd be binning it and buying a new one

Capacitors of a size that could leak electrolyte aren't used in a modern TV - they do spit cotton wool and aluminium bullets though. If the TV is 12v there's no danger from it wet or not. Go around the case with a slim blunt knife - there will be latches in several places.

Liquid dripping through from the cupboard above...

 

[mike mcglynn]

I had a problems with a tv in the house and it turned out tha aerial cable was full of water ,when I disconnected it the water just ran out.

 

[Rapidorob]

Thanks everyone for your replies. I can definitely say that it isn't water coming from the aerial cable as the aerial first runs into the wardrobe and then to an aerial amplifier. If water was getting into the van that way it would affect the amplifier not the TV. The output from the amplifier is internally run around the van to the TV cabonet. There is no evidence of water ingress within the TV cabinet. The only damp is on the casing of the TV and since removing it due to the fault with the remote not working I can see that brown liquid is still (after a couple of days) leaking out of the set and it is sticky to touch. On my fingers it is like the sticky residue from a leaking dry cell battery!
I have tried to prise off the back but without breaking something I can't shift it.
The set works but I can't find a way to set auto tuning running. The buttons on the set allow me to select auto tuning but nothing I try will get it started.
So it seems that a new set is needed. Any recommendations?
I can't accomodate larger that 16 inch in my TV cabinet.
Thanks for all your help and advice.

Instead of being limited to having the TV in the cabinet, why not mount one on the wall below the cabinet and use the space above for something else, that way you could have a larger TV if you wish.

 

[Gellyneck]

I've (think) heard of a potential uncommon fault with lcd panels on laptops leaking fluid. Only way to fix was to replace panel but .......

Hi Mel, Our van is only 6m long so we don't sit far from the TV, a 16 inch is big enough for us and goes neatly out of the way and out of sight during the day so I wouldn't want a bigger screen.
Hi Gellyneck, thank you for sharing that with me perhaps that is where the fluid is from. What's strange is that apart from the remote control receiver packing up, no other fault has been apparent. If the screen can leak fluid without apparent degradation that may well be the fault. It is interesting that ReallyRetired above had the same problem with a Kogan set.

 

[Richard n Ann]

It's probably MBBA leaking out of the screen. It's poisonous and causes skin irritation.

[GPW]

Take it out of the van and unscrew the back. The source of the leak should then become clear!

 

[Rapidorob]

Hi Richard and Ann, thanks for your reply, that could be it.

 

[Rapidorob]

Hi GPW, As mentioned above, I am unable to get the back off after removing all screws and applying significant pressure I have given up.

just bin it and move on

 

[Rapidorob]

Hi All, I have taken DavidG58 advice. I have ordered an Avtex 168DRS to replace the Kogan. Thanks for all your advice.
