Special monitors cables

---

The day to day Workshop always brings something new that turns out the story and then experience. An occurrence that can take the Technician in "standing against" is related to the signal cables for monitors. Some brands of monitors such as TCE, Daewoo, Video Compo and some HP , which use standard DB cable connectable = 15> DB9, the pinout is different from most because the timing pin is inverted in relation to the Samsungs, LGs and Other popular. When a monitor of the first mentioned arrives to the workshop without the signal cable DB15 => DB9, if we connect on a normal cable for Samsung, for example, will be without Horizontal sync, giving the impression of a defect in this step, even if the complaint is another.  Worse is if the device went dead and Technical repaired the source. By connecting the image has no timing, because of inadequate cable. In one of these, one can spend much time looking for a defect whose cause is not found in the cooling circuit. So keep in mind: these monitors use cable itself, while the standard DB15 => DB9. However, there is a caveat: If the cable is DB15 => DB15, has no difference with the other monitors more popular, and can use the cable for any of them, "without war." PINOUT CONFIGURATION OF VARIOUS CABLES Normal  = DB15> DB15     It is pin to pin . Example: 1 with 1, 2, 2, 3 with 3 ... by 15 to 15, except that the pins are missing on some cables. 6, 7, 8, 10 and 11 are lands. Even if some break, yet continue to function normally. The main ever be missing are 1, 2, 3, 5, 13, 14 and the digital displays 12 and 15 also.
