Fix a bad flex tab? From a tv

[Anum22]

Hi, ive been doing a little reseach on how to fix this, but i want to know is it possible? Soldering the thin wires? My kids watered the tv, so then i opened it found a flex tab that had been eaten from corrosion. Please tell me how to hard wire them, its already damed but want to give it a try. I don't know if i should have , but i peeled the tab off.

Thanks for the help

That sadly may not be repairable. Those are fused on with some kind of epoxy I believe. You could try heating it with an iron but don't think it's going to get very far.

i`ll subscribe because i`m very interested in this type of repair!
If there is one

I watched this, and at the end he said you could try, but i want to know exactly how?

I'm pretty sure that's not repairable. Too fine for any one to do by hand. Need an expensive dedicated machine to do that.

What about that 3M conductive tape that only conducts in one parallel direction ?

Re: Fix a bad flex tab? From a tv

But is there a way that i could try? Its damaged anyways, just want to experiment ? Would the 3m tape work?

Re: Fix a bad flex tab? From a tv

Worth a shot, I suppose - it's the alignment that's going to kill you, the individual lanes are probably 0.05mm apart. If you can line it up, maybe... Big, big maybe.

Have you ever tried somthing like this?

[tom66]

Re: Fix a bad flex tab? From a tv

No, and I've not heard of anyone doing it either. If you do it successfully:

So, i should try with the 3mm tape? Sorry if i ask too many q's , or try to solder it? Also read about a silver pen?

Re: Fix a bad flex tab? From a tv

It's definitely NOT solderable, you'll break it. Feel free to try other methods.

Re: Fix a bad flex tab? From a tv

What about conductive copper tape? I just saw it on ebay? Which one should i try?

Re: Fix a bad flex tab? From a tv

Please tell me , is this what i need to get ? To try to fix it? Is it the same way?

Re: Fix a bad flex tab? From a tv

check this out I have a BMW that has a digital display in the instrument cluster and these cars are known for their problem with these having ribbon cable problems here's a good video how to replace the ribbon cable and inside the instrument cluster on the circuit board is very similar in fashion to the top driver boards on LCD so check it out maybe I'll give you some insight.

Yes the ipod seems the same idea as well

I don't exactly know but I would guess that tape may not be suitable for an appication where the temperature fluctuates so much, an Ipod I'm sure is fine but in the back of a Tv, I'm not so sure. The way I see it is heat is used to remove sticky things, whether they be glass digitizers from phones, Ipads or ribbon tabs as he showed in that video, so if it does work, and because of the heat generated, I don't think it will last long if indeed it works at all but as ever, you have to try to see, so good luck, if you do go down this root it will be interesting to see and hear what the results are, Andy.

Re: Fix a bad flex tab? From a tv

Thanks i will update , as soon as i get the tape.

Re: Fix a bad flex tab? From a tv

Yes but remember in a car with summer heat these things can get extremely hot. The tape adhesion is in the ribbon.

The difference I see between the two fixes is the BWM guy is actually using just simple old sticky tape to hold down that type of ribbon cable in place, the Ipod guy is using this special conductive sticky tape that the OP desires to use in this application. The tab bonds do require some level of mechanical strength where as the BMW fix looks to clamp firmly down with the four screws giving the mechanical strength required. I just see this becoming the infamous tab bond issue extremely quickly what with the heat variations that will go on, especially around the tabs, I would have to advise on some pressure over the areas concerned, plenty said here on how that's done.
