Right after it went out of warranty, the meters of my Digimax LT got
strange. On power up, channels 5-7 go on (all three LEDs). After that,
channel 5 stays on and channels 6-7 all light with any amount of signal.
Any idea where to look in the circuit to see if it might be a quick fix,
so I don't have to send it back in? I know enough to be dangerous and to
fix a lot of stuff, if it's not too complicated and I certainly can
wield a soldering iron.

TIA
