Dear all,
In my device, the "gentleman" who assembled the scope, left the flat flex cable of the LCD in the battery holder. As a result, the cable broke just when I needed the scope.
I suppose a replacement can be found pretty easily, but I am no expert, thus I wonder what aspects I should look for.
To me the cable appear as a 12 way 1mm pitch flat flex ribbon 9 cm long.
The pitch and the number of ways cannot change, of course, but I dunno if thickness and the length have to be the same as well.
In a printer I found a flat flex cable, 5cm long, with 50 ways or so. This cable is also a little more thick than the original. I cut out the 12 ways I needed, and put the cable in place.
Well, the screen lit on, but it remained blue without showing anything.
Now I wonder about the reason.
I dunno if the problem is due to:
- the pins that may be oxidized.
- the fact that the cable is not an original 12-way cable and the pins end out of place?
- the thickness, that may cause the cable not to touch correctly on the pins
Also, if I put on the original broken cable, and pinch it over the cut with my fingers, so that the broken ends of the cable touch, something is shown on the LCD.
Sorry for the much details. Please if you have any suggestion tell me.
PS.
Out of curiosity I "naively" asked Tektronix the spare part.
- "We are sorry but the part you request is out of production. However you can send your device for repair to our service center in Cologne." (I live in Italy)
- "How much would it cost?"
- 1k € plus shipping
