Getting the back cover off JVC telly

sooey · 3 Aug 2015

Does anyone know how? I've took all the screws out but it's still as solid as if they were all still in.
There must be some kind of magic clipping arrangement on it, if anyone's got a clue I'd be most grateful. Ta

You *think* that you have taken (not took) all the screws out.

The fact that you can't get into it suggests that you probably shouldn't. If it's faulty, my best advice is: take it to a competent repairer.

In any case, JVC "badges" TVs from more than one manufacturer so, without knowing the specific model number, it's impossible to know which TV you are referring to.

If you still want to open it, please provide the model number and good resolution photos of the rear panel. My initial guess is that you haven't removed the bolts holding one or more sockets.

I *know* I've tooken

all the screws out Sam, scart socket ones included. Unless there's some invisible ones which I can't see.
The model number is LT-39C740(A), can't do pics but take my word for it, all screws removed.
My feeling is that if it were just one or two screws holding it it would be loose around some edges at least.
This thing is as solid as if all of the screws were still in place.
There is one thing to add, there is a small rectangular hole near the bottom of the cover just left of centre, this has a padlock symbol next to it stamped with a letter K.
I'm wondering if there is a tool which has to be inserted here to release whatever mechanism is holding the cover on, though I've shone a light down and can't see anything obvious.

No, that's a hole for a security device called a Kensington lock. It's an industry standard method of attaching a steel security cable to portable/moveable devices. It is nothing to do with releasing the back cover.

If the TV still has the table stand attached have you tried removing that?

Cheers for the explanation, that's that ruled out then.
Which makes it even more of a mystery, no stand attached.

Sounds as if all you need is a TV engineer's standard pry bar:-

Got there in the end, lots of little locating clips around the edges which can't be seen when assembled.
I started prising it apart with a bread knife in the end which was when I discovered these evil little bstrds, once you've released enough of them the rest release as the cover comes away.
Did me no good though, I was hoping the problem may be something obvious like blown capacitors or burnt out resistors but everything looks fine visually at least.
Never mind, new telly for the kids on the cards.

Offer it on eBay. Be sure to include good clear photos of the outside and of the internal boards, together with a clear description of the symptoms* and "no visible fault inside". With luck you might get two TV repairers bidding against each other.

*I.e. what you see and hear when you press the on button, for example. Note that a description such as "dead" is NOT a symptom - it is your own interpretation of the symptoms, which might be incorrect.

There's a guy on ebay flogging the same supply board (not new) for 26 quid, might have a dabble at that if he confirms that the telly it came out of died of a different fault to this one. Which does nothing at all when you turn it on, dead IS the word.

No TV repair man me but the thought has just struck me that this crappy telly has no on off buttons just relying on the remote to do it's stuff.
It's far more likely that the remote has been dropped and isn't working than the telly's broke. Why I didn't think of that before I'll never know.

My neighbour waited 6 months patiently for me to look at his TV. He HAD put new batteries in the remote. Eventually I told him I had a spare hour and he should bring it right away. He did so and, as he placed it on my bench and plugged it in, he asked "what's this button at the rear next to the power socket? It's marked on/off".

He pressed it and his "dead" TV lit up.
