LCD Number on Signal Generator has a line out

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.

Grant.

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.
