Sir please will you tell me that what is the colour of sync signal and vertical sync signal in lg 15 pin vga connector or else provide me a full description of lg 15 pin vga connector with colour code and diagram

Refer its connection diagram. The user manual might help you. If not, contact any service technician.

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.

pin no 1 - Red colour signal (Red colour wire)
pin no 2 - Green colour signal (Green colour wire)
pin no 3 - Blue colour signal (Blue colour wire)
4&5 Not connected
pin no 6&7&8 are (Grounds)RGB Returns
9&10 NC
pin 13 Hohizontal sync signal
pin no 14 vertical sync signal
Not nessasry other pins

pin no 1 - Red colour signal (Red colour wire)
pin no 2 - Green colour signal (Green colour wire)
pin no 3 - Blue colour signal (Blue colour wire)

pin no 14 vertical sync signal

1. cpu problem. why because of there is no signal output from cpu to monitor. the led blinking means there is no vertical, horizontal signals from cpu to monitor.

2. your monitor connected to another system.

3. neck board dry points.

4. cheak the display cable. 13&14 pins are horizontal, vertical signals.1, 2, 3 pins , R G B , 6 ,7, 8 pins R G B ground ( coaxiler cable used , meshed wire is ground )

Hi,

Pls find below the Pin configuration.

Pin 1 - Red Signal
Pin 2 - Green Signal
Pin 3 - Blue Signal
Pin 6 - Red Ground
Pin 7 - Green Ground
Pin 8 - Blue Ground
Pin 10- Horizontal Ground
Pin 11- Vertical Ground
Pin 13- Horizontal Signal
Pin 14- Vertical Signal

Best Wishes

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.

This is solved by the author himself

i want to know that what is the color combination of vaga cable connector
