| 344924 | 2005-04-24 12:08:00 | I think I can answer that Nooooooooooooooo! Rewired the male plug. Not as easy as I thought it would be ended up with blurring on screen even though I insulated any bare wires. Did it with a couple of connectors same problem everytime. So I thought right; I will splice the wires together because the connections would be fully insulated. Worked on the basis of pairing the same coloured wires and isolating all the others. Result : NO SIGNAL on the monitor self diagnostic. So either someone has a diagram for the loom for this extension (which is unbranded) or I'm going to have to strip the spare connector (the one I was going to use on the other monitor) to see how they have wired the connector at the manufacturers and then go buy another extension to splice for the second. Luckily there quite cheap. The question I have is: The voltage is low but do you think if I go through a process of elimination I could fry my graphics card? |

| 344925 | 2005-04-24 23:15:00 | The problem with el cheapo male to male monitor extension cables is that they do not have proper screening, so the screen picture can end up very poor quality. The three colour signal leads are nearly always coloured to correspond ie reg, green blue, and they are each separately screened. Only 9 wires need to be connected to get the monitor to work ok, 3 colour signals, 3 colour grounds, 2 sync signals and a main ground. The standard wiring to the 15 pin plug is: Pin 1....Red video Pin 2....Green video Pin 3....Blue Video Pin 4....Monitor ID2 Pin 5....Ground Pin 6....Red Ground Pin 7....Green Ground Pin 8....Blue Ground Pin 9....No Connection Pin10....Sync Ground Pin11....Monitor ID0 Pin12....Monitor ID1 Pin13....Horizontal Sync Pin14....Vertical Sync Pin 15...Monitor ID3 Now the essential connections are the colour signals and their screens. They should be coloured red, green and blue with black insulation around the screening, but sometimes one of them may be another colour like white, so you get red, white, blue. There should be enough info there to sort out which is which. The colour signal leads are the only ones to be individually screened. Then connect the leads that go to pins 4, 10, and 11 together. The outer grounded braid will connect to pin 5, but it is obvious that the outer braids will be joined. That leaves the two synchronisation signal leads going to pins 13 and 14. You can experiment connecting these until the picture 'synchs' properly. It won't do any harm interchanging these two whilst determining which goes where. Ignore pins 12 and 15. You will need a multimeter to trace the wiring from the pins of the male plugs, but you do really need the proper screened cable. If yours that you bought does not have screened leads going to pins 1,2, and 3 then it is no good. Edit: PS I do have a Fujitsu cable in my junk box, but I wouldnt be able to separately identify it from all the others :confused: |
