Digital circuits have more noise than analog so that mainly digital board can send it back into other power rails that are also used by the analog video circuit. This is why KBK found such an improvement in correct color representation and line drawing stability in the Marquee after he lowerd the digital noise on the Control Modual of the Marquee by adding more buffering at each chip on that board. Higher Signal to noise ratio is what helps lower that noise. thats is why when you removed the power to the digital convergence board the video noise went away. Find away to lower noise going back out on that board and your video will improve. Like Mike Parker says higher bandwidth isn't the only thing that helps a PJ run better at higher scan rates, Id be interested to see how well he can tame that boards noise, if he cant do it no one can He is the best.

My Runco 1100 (BD1209s) has HFQ900 lenses on it, which boards in it are different from the graphics machines?

I meant which boards are different between the 1209s data and graphics chassis? I want to get the bandwidth back up.

Hi,
The video chain is the same for both models, and video bandwidth is the same.
The scanrate is the limitation imposed in the Data. Runco also limits scanrate in firmware.
You would need the H board, control board (or firmware), and H coil/relay board at a minimum.
AndyH has mentioned possibly needing the V board. I have a nice 1101 here, and have
considered converting it. The only real need would be for 72Hz 1080P or the odd HD sources
which have cutoff edges, where the faster retrace will allow them to display correctly.
Cheers,
Galen

I don't want to hijack this thread so I'll start a new one. I have some parts from a 1200 that I got from Phil Smith.

I think you can also throw in the vertical board as needing to be replaced on your list ...

Hi,

Hi Bernd,
i'm still waiting for my eye-one sensor
BTW: Do you warmup the projector for 20 min everytime before you watch something ?
thx
ElTopo

Bernd,
I forgot completely about your Private Message. Does the problem still exist?
BTW: Eltopo, good work, but you really need to take better pics. I don't see a difference with my first CRT, a very soft 6,600 hr Sony VPH-1252QM

Bernd,
Can you please elaborate on this? I want to try this out, but am unsure what I need to disconnect from what.
Thanks in advance!

Hi Peter,
that has no meaning, because you need the Convergence Board

ElTopo, your "eye" shots still need lots of work.
Here's the same pic on my NEC 6PG Plus at 1920x1080i96:
"Pete's" eye
Obviously colors are off (mostly due to camera settings)
Kai
Edit/Update (this is just the same as my post on the next page):
for reference here are Pete's original pics:
This clearly shows that none of us have managed to nail the colors
Of course camera differences (like white balance settings and saturation and so on) play a major role in that. As does the color space of the photo and the capability of the picture viewer to properly handle color management.
IIRC my screenshot was taken right after a tube replacement, and prior to calibration.

its probably like on the Marquees, if you go close to the screen and look at the grid on a marquee you can see it moving/dancing very slightly, if you pull of the convergance conectors, NOT THE VERTICAL DEFLECTION CONNECTORS!!!!! you will obvioulsy loose convergence but the lines will not move anymore, the noice from the digiral circiuts on most convergence that is controled digitaly adds noise to the projector and affects many things like stability as shown by this test and some noise in the Video.

Hi,
the Video Noise without moving!
The Power interrupt is without significance for the Elimination. You need the Board in Action!
