Sony VPH-1031
 

A friend of mine came over with another heavy hungry mouth and gave it to me. A Sony VPH-1031 CRT projector. I pulled the lenses to check the CRTs and it is very low hours! It works great on composite but requires a non standard RGB cable to work 480P. Has anyone ever dealt with this. The website that is listed on Curt Palmes site no longer exists. This machine is interesting as I am used to my VPH-D50 which is much larger and heavier.

If it has a DB25 connector for the RGB input, it may use this pinout:

Pin Signal Descr
---------------------------------------------------------------
1 IBM Select High: IBM mode (RGBI)
Low: 3 Bit TTL (RGB)

2 Audio Select High: Audio input from pin 13
Low: Audio input from LINE A/B/VTR jacks

3 HSync/CSync Horizontal or Composite Sync, Negative Pol.

4 Blue Input Video Inputs: Positive Pol.

6 Red Input

8 NC

9 Analog/Digital High: Analog mode

10 RGB/Normal High: RGB input selected
Low: LINE A/B/VTR input selected

11 VSync Vertical Sync, Negative Pol.

12 Blanking High: Video input from RGB input only
Low: LINE A/B/VTR signal is superimposed over
signal from RGB input

13 Audio Input -5 dB / 100% mod.

14 NC

15-24 Ground

25 intensity Positive Pol.

Oops, the columns are garbled in the post though my original is correct, but you should still be able to see what each pin is for.

Many thanks! I'll start figuring this out this weekend.
