I just got a CV that seems to be acting funny.
When I first put the batteries in, it didn't seem to come on unless I would reset [on] <=.
Then after repeatedly pressing on it now seems to be alive.
What would cause the display to light up 1/2 a second after pressing on? Is this normal? The CX I have doesn't seem to have this lag.
Also, as I ever so slightly press the on-user-prgm-alpha buttons, the LCD will fade in and out.

I'll assume this is a Coconut, as the symptoms are quite likely to come from a bad CPU to keyboard connection: contact strip failure or broken post are common sources for this sort of (somehow) weird behaviors.
Hope this helps.
