Some New Updates on the monochrome 9 monitor !!!

<< < (2/5) > >>

Ken Layton:
I think you have the Omnivision monitor (Model LP-0915Gxxx) used in the Arachnid "English Mark Darts" 6000 series coin op dart games.

Made for CGA resolution and composite video.

The monitor came from an old CNC machine Siemens i think,Its a Magnetek 579417TA (MONITOR 9 MONOCHROME)

Its exactly the same on picture !  :)

If you look at the TDA 2595 there is pin 9 that isnt connected to anything and the
datasheet of this chip says that its composite sync out or something so its clearly
missing some signals from those pins(also 7,6,1,18). ?

And yes I already tryed composite video(signal) directly on pin 11 but no affect   :-\

Help would be welcomed !

qrz:
standard composite input "#3"  on ur drawing .

couple TDA2595 pin 9 (sync out) to "#2 via .047 -1uF cap.   

"should" stabilize sync   ?

TDA1175 vertical processor/output
TDA2595  h processor/sync sep

be VERY helpful to have an EIA standard schematic on this . no luck thus far  :'(

I have some good news, I finally got a decent picture on the crt screen,but there are still some minor problems,like those slightly
curved lines thru the screen and the black space on the two sides of the screen that arent filling the screen completely ,but
other then that its pretty good I ques  :D

By connecting the Video signal input(yellow 1) to pin 11 on TDA 2595,and composite video signal from VCR connected to
pin 11 and then the pin 9( vertical sync) to TDA 1175p pin 10(sync input),but there are still these curved lines that
annoys me   :(

qrz:
if reducing the screen voltage  has little effect ,
the blanking pulse is not being coupled .
will have another look at the schem/specs when get the chance ..........
