I think its a very nice upgrade to the new OLED screens! I ordered a screen about two weeks ago and it arrived the other day.
I have now installed it and loaded it up with the new firmware (rev209) and it worked straight away
It's looking very nice!
However, I'm having one BIG problem
Background noise/hiss. It's not there when switched off, dead silent like it should be.
When powered on it's either quite loud or quite silent. Whenever I enter the menu it's always a loud hiss. When going back to the volume control most of times it goes back to a small background noise (still a lot higher than with the 7 segment display), but sometimes the loud hiss stays and then it usually gets less intensive from adjusting the volume but not always.
Info about my setup:
V25 in a balanced configuration (2 balanced in, 1 single ended in, 1 balanced out)
Power amp with plenty of power (that's why even the quite silent hiss is bothering me)
DAC with xlr
What I have tried so far:
Disconnected all cables, plugged some back in, skipped the preamp - identifying the preamp as the cause of hiss.
Power on power off
Kill the power
(Many) AutoCals (finishing without any problems, also making sure the preamps been on to stabilize temperature)
On some of the AutoCals the hiss started on one specific LDR (usually between steps 30-80). I did replace those specific LDRs but results are the same.
I don't think any of the LDRs are causing any problems (since it worked fine before), I think the screen/firmware is. When entering the menu the loud hiss always starts.
One more thing, the loud hiss is following the volume, well kind of at least.
First off, mute is not working, volume 1 is like a middle hiss, on volume 2 the hiss is loud and increasing between volume 2-60, between 60-100 the hiss is decreasing, on full volume the hiss is almost as low as on volume 1 (middle hiss.)
I'm not sure how to proceed. Any ideas?
