    Broken Monitor pin

    Locked

    by mrcpac ·

    My CRT dell monitor has a broken pin, so i cut the cable to try and solder it or use one of those male connectors with screws. Problems is where the colors go so far i have managed the RGB only and left with the following, Yellow, Brown white, black and the silver!!

        It still does not explain where the colours , yellow, black and white go to ???

          You need to check this with a Multimeter/Ohmmeter

          In reply to Not quite

          From the Old Plug to the Wire where you cut it off.

          That is the only way to find out which pin goes to which color unless you want to pull the monitor apart and trace from inside it. That’s not the best option though and a simple Multimeter and the bit you cut off is far easier. 😉

      Color code manufacturer specific

      If you still have the old connector, an ohmmeter will allow you to determine the correct pinout for that cable and the connector. Color codes are often different from manufacturer to manufacturer. I’ve had to replace dozens of VGA connectors for clients and this was the only method to replace the connector.

        So I guess I’ll second this approach as the right one.

          I’ve had so many clients that bought new monitors when they broke or bent over a pin on the connector. I’m more than greatful to take them off their hands and with the cost of a connector and a little time with the soldering iron, return it to full operation. Now I’m starting to see the same thing with the newer LCD units too.

          Is there a chance that if i get the wires mixed up it will damage my pc cos i dont have any testing kit??

          Why risk it? Make your own…

          … with the bulb and batteries from a flashlight and a few lengths of small wire.

        Why use an ommeter?

        In reply to Color code manufacturer specific

        Just cut the back off the connector he cut from the cable. Whoomp, there it is: cable color code on the back of the plug.

          In reply to Who says we don’t know how…

          All he has to do to match up the pinouts is face the female end of the connector toward the monitor and match up the colors from bottom left to top right.

          If the cable was removable.

          Depends on the model

          If I remember correctly, the higher end Dell CRT models usually do have removable cables.

          The reason I use a Ohm Meter

          by oh smeg ·

          In reply to Why use an ommeter?

          Is because with some of the Molded Plugs you run the risk of cutting your fingers badly when you cut them but more importantly

          I’ve seen a few that tear off the Internal Insulation when you pull them off. Then all you are left with are the bare wires sticking out the back of the Plug.

          I’ve seen this quite a lot with the Molded Plugs filled with Silicon.

          But if there is no multimeter available a Battery LED and some short bits of Insulated Cable will do exactly the same thing. I’ve used Sewing Needles to stick into the Connectors of Plugs to make sure that you don’t slip off one pin to another or short out more than 1 Pin at a time. 😉

          I have an Ohm Meter

          Okay i managed to get my hands on an Ohm Meter, so what do i do now??

        • #3015812

          Set it to the lowest Resistance range and grab the old plug

          by oh smeg ·

          In reply to I have an Ohm Meter

          Strip a bit of the insulation away from the lead side of the end that you cut and expose the internal Wire, Shield and it’s Insulation.

          Then strip a small amount of the Colored Insulation off the internal wires and with the Ohm Meter test one Pin at a time with the other probe held against one of the Colored Leads that you do not know what it is used for. When you get either a Noise or the needle swing tot he end of the scale or if it is a Digital Readout the readout shown a very low number as apposed to all zero’s you have that wire and which pin it goes to.

          Make a note of this Pin Number and then move onto another wire that you don’t know where it goes and repeat the process, The Shield should be attached tot he outside of the D15 Socket the metal Part that goes around the outside of the Pins and this is a Common Earth/Neutral.

          If you already have the RGB Wires Isolated there should then be the Vertical Sync a Positive and Negative a Horizontal Sync again a Positive and negative and a Pair of Wires used to switch the Monitor into Power Saving Mode. You should have 6 Wires that you need to attach tot he plug and don’t worry not all of the pins are actually used. 😉

      Buy a new monitor. their cheap enough.

      I simply wouldn’t waste the time and effort to fix a CRT.
