Ruined a ribbon cable on a Xenarc 705TSV monitor. What do I do?

**Maheriano** · 10-07-2009, 08:52 PM

So I got the 15 inch cables from the mp3car store and they're not working because the pins are now misaligned and not making direct contact with the pins on the cable. See the pictures:

What's the best way to align these again? Some sort of super magnifying glass and a thin piece of metal? How much is a new Xenarc LCD panel you think? Does mp3car sell the panels themselves or do I have to get it from Xenarc? And is there some sort of easier way to replace this cable acceptor on the board?

When I broke the pins from my touchscreen overlay on my lilliput, I just soldered them to the circuit board, but i would doubt you'd wanna do that for 40 pins lol

Well looks like I just bought this busted monitor for $200 and he ordered another one for $340 to the door, next day delivery. So I still have to get this screen working to put it in my car, any more help is appreciated.

But I'm also wondering with this screen......the bent pins are on the side of the ribbon cable with the black stripe, the exposed pins on the cable are on the other side. These bent pins aren't contacting anything so would it matter at all that they're bent? Who cares right? And I have the original ribbon cable to make sure I'm actually facing this new cable the right way which is correct. For some reason it's still not working with the new cable, I thought it was the bent pins initially but if they're not contacting the cable it can't be that. I'm lost now....

i don't understand your question...if you have bent pins not making contact that is a problem...the pins make contact to the wire...a flexable conductor to conduct a signal from one place to another...if that signal (1) doesn't get transfered...there is a loss of data...it will always think that there is a 0....They would not have put the pins there if they didn't need to be connected to anything...

You can see it in the picture. The ribbon cable slides under the pins that are bent but that black part on the ribbon cable which is facing you doesn't have any exposed metal. The exposed pins on the cable are on the other side of the cable, facing down, making contact with pins underneath. The bent pins here aren't making contact with anything on the old busted ribbon cable, nor the new longer ribbon cable.

ok...still have no idea what you are trying to describe...but what I am saying is...

IF YOU DO NOT HAVE SOME PINS TOUCHING, AND THE DEVICE IS MALFUNCTIONING, THAT IS YOUR ISSUE...IT'S NOT OK!!!!!

How do you not understand? The picture is pretty clear, you can see the pins sticking out and you can see the black band underneath them. The pins aren't actually touching any of the metal leads on that ribbon cable because the metal leads are only exposed on the underside. They would only make contact if I flip the cable over but that's not the way it goes. It goes like in the picture which leaves the bent pins not in contact. Anyway, here's an email I got from Xenarc Support:

Hi Daniel,

Sorry to tell you, your LCD panel is shot. First of all, we don't sell the
brown clip. Neither does the LCD panel manufacturer. The brown clip is
important in that it puts pressure on the flat ribbon cable thus creates
contact with the connector. Second of all, the pins are bent. Yes, the
backlight will not turn on if the flat ribbon cable is not plugged in
because that is where the backlight gets power. You are looking at a new
LCD panel, which runs $120. By replacing just the flat ribbon cable is not
going to help your situation.

So I'm either going to get this panel working or buy another one for $120 USD + $20 USD shipping + $30 import duties + $20-$30 conversion to CAD = about $200 CAD shipped to my door. But I will try everything I can to get it working somehow.

Oh I didn't know the zif connector had pulled off. Yikes.

Yea unless you can micro solder you don't have a chance at fixing it . Sorry.

Or did you just break off the brown slide out connector?

If you just pulled off the brown slide out connector you could by a new zif connector and pull off the slide out brown lock and pop it on the old one.

But yours might be a flip down not a slide lock. Hmmmmm

ok...reguardless of if I understand what you are trying to explain or not...you need to fully read that statement...ALL OF THE PINS NEED TO TOUCH THE RESPECTIVE PINS IN ORDER TO WORK!!!....there is really nothing left to your question...what do you want someone to tell you...ALL OF THE PINS NEED TO TOUCH WERE THEY SOULD ON TEH CABLE...what are you trying to ask???

Umm you don't seem to understand. The lcd cable is held in by a zif connector. You slide in the ffc and then lock down a tab which puts pressure on the cable pushing the ffc onto the pins.

Without the locking tab there is no pressure and the ffc won't make good contact with the bottom set of pins.
