Default Brightness/Contrast

Recently the brightness/contrast has been going really dim to the point that I can't see it at all. If I catch it soon enough I can go back into the Contrast settings and adjust it by 1 and back it will return to normal. It's just getting to be a pita so if anyone has suggestions please do chime in
Thanks,
Derek

Other people have reported something similar, but I think Bill is going to have to see this. I sure don't have any suggestions for you. Derek, I'm guessing you have the monochrome Gryphon, not the newer CS/CTS platform?

That's really odd that the contrast would start going dim and then changing the setting in the options restores it. A couple questions:

How frequently does this occur? Every key cycle? Frequently? Weekly? Every few weeks?

Once it starts to dim, how long does it take for the contrast to dim completely out? A few seconds? A minute?

Does the PID display still function correctly when the contrast begins to dim?

If you can't make it to the settings, how do you get the display to work? Turn the key off? Unplug and then reconnect the cable?

I don't have any idea where to even begin to look on this, so any information would be extremely helpful.

Thanks!

I've had mine do that a few times. Next time, while the vehicle is on, unplug the unit then plug it back in. That has always fixed it for me. I think it is heat related.

Perhaps it wasn't as "similar" as I thought. But, Bill is the guy who can help you with this. Glad he's found the time to monitor the forum.

Edit: Longshot, you snuck in here as I was typing! Good suggestion - can't hurt!

It has been doing it a few times a week lately but for a while it was an every day thing. I would guess a minute+ for it to completely dim and everything still works like it should. Turning the truck off/on does return the contrast back to normal but I haven't tried unplugging/plugging it back. I also had taken the heat into consideration but it has been hotter lately than when it acted up more.

Thanks,
