Check this out, when I set the dimmer to lower than about 60% the bottom 1/4 of the display goes way lower than the rest. It looks fine at 100%.
I just got the player, from the looks of it it has very low miles on it. Warranty stickers were still in place and the whole bit.
Any ideas?
(I simulated the display in the attached pic with photoshop)

Greetings!
Hmm... I have not seen that one before. Could the display be faulty? There was a FAQ entry about testing voltages for dim displays, but that was the entire display, not a region.
Is this with "stock" software? Both AC & DC power?

Using:
2.00-beta13
Hijack 320
Yes, it happens in both AC and DC modes, but of course, only in AC mode when faking DC via hijack.
I am hoping that if something's faulty it will be the cable and not the actual display unit itself.

Valid point. I forgot the dimmer option wasn't in the other mode.

I too have the same problems if I turn my dimmer to about 40% or below, parts of the display become dimmer then the rest. I've always attributed it to capicitor issue and was intending to have it fixed when I got around to ordering a backlit button kit.

Could this be a Colorado phenomenon?

Mine gets a little uneven at 30% or less, but not that bad. However, my clock has never worked (different capacitor issue). I checked the voltage on the Supercap and it is indeed shot. I just haven't gotten around to replacing it.

I thought the cap issue affects the display as a whole, as it's the data line to the dimmer chip that caused the problem. Could it be a dodgy heater wire in the display that's causing the dark band at the bottom.

That was my first notion!
I am hoping that it is not the problem!

In reply to:

I was also thinking that. I tried to see if the unevenness I had on the display was around the wires, but couldn't see them through the lens.

Well, I took it apart a few days ago and looked em over. I didn't notice any difference in the lower wire(s). They all seemed to be attached well too, although you can't really judge anything by that.
I need to pull it apart again and do some further tests.

You can actually see the wires glow slightly when it's on (or maybe it has to get ``warm''), especially if there's nothing blocking the view. Try leaving the lens off and compare the wires when it's displaying something.

I had something similar to this that was fixed by the dimmer fix and reuploading the firmware. When my player came back from support, I put it in, and it had sections of lighter and darker parts of the screen just like it had before. I put an orginal .upgrade file on it, and everything returned to normal. I don't see why it would have any effect, but it worked for me, so you might want to try it.

I'll definately try that too. I agree that sometimes it's the things that should have no bearing on the problem that end up solving it.

I've been waiting for a backlit button kit for a year now. You might want to get on the list!

Greetings!
Was there a low voltage on the display capacitor, or any visible problem with the heating wire? Also, does it happen with both lights on & off with the dimmer setting? Is it only at 60%, or does it get worse as you go lower?

Heating wire glows red the same as the rest of them and looks fine.
Voltage was within the 54-60v range.
And it happens both with lights-on and lights-off dimmer settings.
I found another post with the same issue
here and have contact them to see if they have found a solution.

My last player absolutely did not have this problem. I know what is normal and what is not.
