MONITOR: Connector Pins Broken (How do I Repair?)

[drake]

Hi,

I have a TVM 4LR VGA 14" computer VDU.

4 of the 15 pins in the cable connector are broken. The Monitor worked
fine when 3 were broken before. The broken pins are 5,9,12,15.

Can anyone tell me which one is the critical pin amongsts these?

I've looked around, and it seems the only way to salvage the monitor
is to either replace the
cable or the connector... both ways involve a lot of work. (But if
this is the only way, I will do it.
Will the small wires inside the cable have identifying coloured
insulation... or will I have
to use a multimeter? Is there any link to a site describing how to
rewire a new connector?)

Dumb Idea: Can I replace the pins in the connector by clipped paper
pins of same dimension/size?
Which I'll solder (or superglue) to keep in position? It seems this
should work fine... but it seems
too easy... what is the catch?

Your comments/advice will be appreciated.

TIA,

Drake Lars

Are you sure they are broken? The 4 pins you mention should not be
critical to basic monitor operation. Perhaps, there is something
else wrong with it.

depending on how old it is.

a lot of work. (But if this is the only way, I will do it.

If there is indeed a pin problem, that's about the only way to
deal with it. You can't really get at the inners of the connector itself
usually because it is potted.

Will the small wires inside the cable have identifying coloured
insulation... or will I have > to use a multimeter? Is there any

No standard, you'll have to use a multimeter.

Not way to assure a reliable attachment. And, then if a piece of the
clip gets stuck in your video card connector, no way to get it out.

Not all the pins are used, but if your broken pins are necessary, then
the complete connector or cable harness must be changed.

If you are not skilled and equipped for this type of work I would
suggest you give it to a service centre to put on a new connector for
you. It is a difficult repair for someone who is not experienced with
this type of work. If you cross some of the wires, make a short, or
make a cold solder connection while doing this, it will not be a good
situation.

This would not be a very expensive repair when done by a service centre.

Don't worry, the pins are not "broken" but were probably never put in in the
first place. It worked that way since it was new, no reason why it shouldn't
keep working.

Seeing how it's a no-name 14" monitor, just trash it and get a good one.

The question is, is it worth getting a 14" monitor professionally repaired?
IMO unless there is something very special about this monitor it is scrap.
Especially considering it is likely there's an internal fault, it doesn't
appear to be the broken pins causing the problem.

Don't do that, you risk damaging your graphics card.

What does the monitor do, if anything? Does it stay in standby, missing
colours, sync problems? A little more info would be very useful.

Ok... the screen is blank.. it does not switch on atall (or else you
can hear a screen switch on with that "thishoooooooooooooooeeeeeee"
sound.

Only the LED is on, all the time. It does not blink atall (as it would
if the RAM or something were lose). The comp is working fine with a
borrowed monitor for now.

The pins are usually hollow. PUt solder paste in the hole. Stick a tiny
wire in the hole, slide on a pin from another connector. Heat to melt
the solder paste. Plug it into the video card and don't ever take it
out. The connection is not very strong.

Super idea!!! Thanks.


Have you tried this before?

Yes, it works great.
But I meant what I said about the solder paste.
If you try to use wire solder, you'll just make
a big mess. If you get solder on the outside of the pins
it will ream out your video card connector, if it goes in at all.
