Hi all,

my Cine 9 is running fine but i have some kind of extreme background video noise. I'm not talking about film grain.

Same on port 3 or on port 5.

Tried 3 different cards (moome and fury). With all the same behaviour.
Swapped also the complete front tray to test but also the same.

Tubes are brand new.


What do you think ? Video Input board / Driver board issue ? Power Supply ? EHT ?



cheers

Found that but what is/was the solution ?

Are you feeding the pj a signal? Is the noise visible on internal test patterns too? HDMI cable issue?

[ElTopo]

Signal is coming from an Oppo with HDMI (checked also different cables but the same).

I have to check the internal pattern.

[HaydnG90]

I would also check the player just to rule that out too. Is the noise visible on the tube faces and on all 3 colors. My Barco 808S would show noise on green with and without video signal.

[ElTopo]

Checked all three colors and it's on all of them.

Also the internal genlocked pattern shows that noise.

So the player/signal should be out ?

try connecting the pj to a wall outlet that is not grounded or unplug all other earthed devices.

[ElTopo]

Thanks. All power outlets are grounded here.

if you have a spare power supply and/or controller card, swap those out to see if the problem goes away.

Thanks Curt.

Tried that but no success.

I'm investigating further....

If you set convergence and geometry temporarily to midpoint, does the noise in the image change at all?

[HaydnG90]

Can you take a pic of the noise. Might be easiest to see on the green. Sometimes that can be indicative of the problem.

No, i did a reset to midpoint already.

[ElTopo]

Anyone tried 817p@96 in the Barcos ?

[ElTopo]

Checked Oppo 203 vs Oppo 93 with the same rez.

The Oppo 93 shows less video noise.

Hi,

it is an original Cine 9 (CineMax).

Mostly visible on very bright scenes (like a Sky with CloudKit) and bad UHD/BluRay masters.

Yes, these are the same.

Only difference is the fan control. Otherwise 1:1
