OK, I have a BK Precision signal gen, model 4011. I've had it for about
5 or more years, and barely used it. I do mean barely. The power cord is
still wrapped up as it originally was. I tried it on my Oscope, and it
is working. In fact, a year ago I took it to an amateur who was capable
of evaluating it with Oscope. It worked fine. I've done zip with it since.
When I turned it on to run it into the Oscope, I found that a digit is
failing. There are four digits, maybe some small version for a decimal
point. When the leftmost digit is a 3, for example, the middle line is
out. It looks like a backwards cap C.
I plan to sell this, and is there any simple repair I can make? Maybe I
just need to leave it on for a few hours. I was about to sell a Plymouth
van last year, since we had no need for it. It had been sitting for
almost a year with just a few drives here and there. When I checked it
out before sale, it had some issues, minor, but annoying. As I began to
use it more, it got better. I still have it and drive it once a week,
and use it for bi-monthly 500 mile excursions to San Francisco/San Jose.
Might work with the gen. Comments?

Depends whether the contacts are corroded or vibrated off, or LCD just
needs a wiggle in the socket. Open up the thing to see how the LCD
glass is connected. Give it a wiggle, unplug/replug.
If it's in a housing pressure mounted against a PCB you may need to
disassemble, clean contact area on PCB, reassemble. If it's been wet,
you have corrosion to deal with, depends what you find inside the thing.

Thanks. Sounds like a plan.

I opened the device and poked around with a eraser on a pencil to no
effect on the 5-digit display panel and wires leading to the display.
There is zero aging and dust inside. It's been in a cardboard box for
quite a long time. I did leave it all on for about 8 hours but that
didn't change anything.
I called the mfger for a part no. They had none, but did have two in
stock simply called the display unit. The device is 7 years old and not
mfgered any longer, although there is a 4011B. $25 for the part. I
planned to sell this. I'm not sure the sales price warrants the
expenditure or my effort to fix it.
