Monitor from CONRAC 7351C19...

Hello, All
Hello Everyone... I have a CONRAC 7351C19 monitor... I really want to connect it
!!! Already applied for both “personnel” and “lowercase”, he just doesn’t want to please
me... The monitor was used in industry in factories... Maybe it requires
inverse signals???
The monitor has inputs, all coaxial, in short, like in Soviet oscilloscopes:
1.Red
2.Green
3. Blue
4. EXT SYNC / H-DRIVE
5. V-DRIVE
There is also a Sync SEL switch - "1.EXT / 2.INT". Each entrance has
switch between 75ohm and HI. Maybe +5v power supply is not enough for him??? Actually he
it shows something, and it even looks like a white screen, but the synchronization does not hold
mentioned, but no technical data...
And one more thing... I have a PENTAGON-128, from which some barbarian took a bite
all capacitors. I will restore them. But I need personnel and
lowercase, not mixed. Can anyone tell me from which microcircuit and which one?
the legs come out with these signals??? Or perhaps there is some kind of microcircuit
which can separate line and frame from mixed synchronization? Although I
I understand that this is a whole decoder and it costs a lot of money...
Thanks in advance...

Hello Robus
As I understand it, these are signals C4 and C6 that go to legs 1 and 2 of DD6 (LP5),
schemes that ran on the forum.
PS I wonder why the clock signal was inverted twice? First on DD71 LP5, and
then also on DD72 LA12... :v2_conf3:

Hello Robus
Rob> Is there a clear description of how video signals work?
Description of which video signals? VGA? Everything is simple there. Here's a VESA table for you,
with which everything can be calculated.

Rob> looked...
I think it’s some kind of strobe, but I don’t understand this, unfortunately, so much
would like to develop such a device. :(

Hello Mike
Mik> If you do it for this price, I will be the first buyer. :)
I don't sell anything I do, I just share... I only make money from
work...
Is there a clear description of how video signals work? What is the duration of the lowercase,
what is the duration of the frame signal? As I understand it, lowercase is essentially
strobe that samples RGB signals??? Or am I wrong... K
Unfortunately, I don’t have an oscilloscope at home, so I would have already looked...
