I decided to de-dust my AE300 today. I've done it about 5 or 6 times at this stage so it holds no fear for me. In fact my Ae300 dust cleaning guide is often linked to on this forum. Imagine my horror when I connected the PJ back up and got a green screen with lines of pixels flicking on and off. AARRGGHHH!!! Then I figured, "oh its probably only a bad Scart connection". Upon realising that the scart was seated correctly. "AARRGGHHH!!!" what the fudge have I done?? Took the PJ apart again and upon close inspection realised that when the free end of the green panels' ribbon cable got caught in the Hoover nozzle, that the wire on the edge of the ribbon had been severed! "AARRGGHHH!!" How in the name of jaysus am I going to fix this!!?? I retrieved the tiniest needle I could find from the kitchen and proceeded to try and work the tip between the two plastic sheaths of the ribbon cable.(ie the 30 or so hairs width wires of the ribbon cable are sandwiched between two thin sheaths of plastic) Tried to stretch one broken end of the wire to the other with the tip of the needle. No joy. Next idea was to try and bridge the tiny gap. But with what? Then I remembered that one of the case screws was stiff and the screwdriver head had sheared off some tiny flakes of metal off the screw head. I magnetised the needle and picked up one of the tiny flakes with the tip of the needle. With the skill of a micro surgeon (If I do say so myself!! ) I managed to insert this tiny flake between the tiny hole in the plastic sheath and bridged the gap. Turned the PJ back on with the case off and........RESULT!!!! . Put the PJ back together and remounted. So the moral of the story is....Despite whatever I said about hoovers in my previous dust cleaning threads. DONT DO IT!! Dont bring that hoover nozzle within 6 inches of your PJ's!! Sure, suck up the airborne dust you've just blown out of the PJ with your air duster, but don't have that hoover nozzle anywhere near your ribbon cables!!
