1 Answer

Not getting any Video or Sync. Power light does come on green but just fades in and out when PC is on and off. VGA connector does appear to be missing a couple pins. Same issue on multiple PC's (Laptop and Desktop).

I have same problem, believe it to be capacitors on the power supply have slowly leaked over the years (mine is Oct 2002).
Some may having bulging capacitors visible. Replacing the bad caps should resolve long start up time.

Hi my laptop went in for repair and they said it cant be fixed as the vga isnt working? what is this and could it be solved


A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and some high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on older VGA cards, which has the same shell size but only two rows of pins).
VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed and 4 pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5 V DC power supply.

the only solution for that is to replace your vga.

Sometimes No Video


Your Vga Driver is corruoted, if you have a Vga card separate reload the driver, if not reload the mother board driver. If the problem still appears, format the PC.

That is the best case. The other possibilty is mother board failure.

Good luck

13pins "from the inside monitor" "to the VGA 15 pins connector


hai dear,
i checked your problem and found that you open the cover of monitor and you find the two jack of data cable in main pcb and neck card( 2 connector of data cable).plz you cut the connector of data cable and you will find 8 wires in connector.related red(invild extra ground),green(invild extra ground),blue(invild extra ground),black gnd,white,orange,gold(extra gnd) and now you cut the red wire, you will find two wires.so you refix the main red wire pin no-1 of connector and red gnd pin no-6,green main wire pin no-2 and green gnd pin no-7,main blue wire pin no-3 and blue gnd pin no-8.check for the horizental sync and vertical sync wire you should go in main pcb which invild the other connector. there is present in print, h- sync(two wire of h- sync main wire in pin no-13 and other pin no-5) and ver.-sync wire in pin no-14.first you will check the whose h-sync and vert-sync in color and now finally other wires will fix any pin of connector.
