Question about InFocus LP120 / 1000 Lumens / XGA / DLP Projector Refurbished Multimedia Projector
If i use the vga cable from the computer it will not show reds. (the pop-up menu will show red when the red is adjusted in the menu) But if i use the s-video port, reds are shown crisp and clear! do you think this is a VGA cable problem, or is it a problem inside the projector? i have tried the connections on multiple computers with the same result, but i have not tried to change the cable. ($50---HA!) i would think this projector has only one video card that supports both VGA and s-video ports and therefore if it was an internal problem, it wouldnt work on either!? OH--and the cable pins are ok. Thanks
I assume connecting a monitor/lcd panel display doesn't exhibit the missing red? To narrow this down, try using the cable with either a different projector or monitor/flat panel display. In short, does the problem follow the cable to these other devices? If so, then even though there are no pins bent over, the cable is probably bad. Cables can develop an internal connection break, even without showing any external evidence. This will usually occur at a connector end, and is often the result of overflexing, bending or other straining of the cable near the connector. Can you borrow another cable from a friend? A couple of other possibilities: 1. A broken solder connection at the VGA jack inside the projector. This can occur, again, if the connection is stressed (flexed, jammed, pulled on etc.). 2. The circuitry just beyond the VGA jack, which processes the video information could have a defect, not passing the Red info. The latter problem is one for a capable technician, and depending on expertise, you might be able to repair a broken solder connection.
