Xenarc 702TSV torn flex cable after custom fit
I bought a 702TSV to replace the old Lilli in my Subaru's dashboard. The reason for the replacement was that the old Lilli was never very easy to see, and the touchscreen has started to fail lately. Sometimes touching the screen does not move the pointer at all or moves it to a point very far from where touched.
The 702TSV is incredibly bright and all my testing so far shows it to be far better than the original Lilliput (which was not transreflective).
Of course I had to modify the display to fit it into the double-din opening in my STi's dash. Now the Xenarc LCD panel snaps into the STi dash from behind.
Anyway, after taking it apart many times and putting it back together for intermediate testing, it failed the test yesterday. The colors were all screwed up. I first verified that this affliction applied to all 3 sources - VGA, AVI2 and internal menus. The most likely candidate for this collection of symptoms was the flex cable.
It turns out that in the disassembly process I overstressed the flex cable that connects the controller to the LCD panel. It has a short tear through pins 1-4 of this 50-pin flex cable.
Be careful with that cable! It cannot be replaced apparently. I had to buy a new LCD panel @ $190 plus shipping in order to fix this.
Fortunately for me Xenarc are very good about selling parts.
It's very sad that now I have this perfectly good and very bright LCD panel that cannot be used for want of a few conductors on this cable. If the other end was removable this would be a $10 fix.
I tried to repair this by jumping the gaps with fine wire, but there's no soldering tip on earth thin enough for this job - at least not when wielded by me. :rip:
