Display console on exercise bike
I have a Bodyworks exercise bike on which the cycle computer (fancy name for something that measures speed, calories, distance) is only partially displaying the numbers. Have opened it up to have a look, all the soldering is intact, nothing is burnt out, have tried contact cleaner b/w the display screen and its backing but no improvement. Bike has hardly been used and runs well but have not had any luck finding a replacement computer, can these sort of things be fixed?

some of these bikes use a AA battery, Mine does. I replaced the battery and it was good as gold again.

Hi Tiger
I had a machine whose display stopped.
Tested battery OK.
Checked battery connections OK
I found that there was an impulse detector (prolly a Hall Effect or reed switch thingo) sensing revolutions of the front wheel, and the display only turned "on" after the display controller received a few impulses.
The rev detector was wired through a dodgy intermittent series plug and socket.
I fixed the connection, and the display worked OK.
Worth a try to check yours, and any other wiring etc.
Also, the handbook may give directions on some unusual sequence of display button taps to turn the display "on".
cheerio, mike

Hmmmm!
in that case, you might find that it is an LCD edge conductor problem.
If it is, you probably don't want to hear that I have had little success in fixing this type of problem over about 25 yrs repairs of electronics with LCDs.
You may just be lucky with an edge and "joiner" wipe clean with soft clean lint free paper etc
(I now use toilet paper!)
bon chance, mike

I have a kitchen timer with one of these lcd type displays.
It also started dropping segments of the display.
The lcd seemed to connect (sit on top of) some thing that looks like a rubber striped strip.
All I did was clean the lcd edge with isopropyl alc., did the same with the rubbery edge it sits on.
Yes I pulled one away from the other.
Didn't work, thought bugger, may have another look in the morning.
Next morning it was all working, still going 5 years later.
Should try and fix that dodgy multimeter that has the same problem.
although pressing on the display seems to make it show the right values.
Don't give up, Try giving it a good clean with an alcohol swab.

Go easy with the alcohol when cleaning the flexible connector with conductive material (striped thing sometimes called a zebra connector), or else the conductive edge connections may be permanently damaged.
Cleaning the LCD display is OK.
You might try to move the flexible connector just slightly sideways (1-2mm) but a lot of electronics have both the LCD display and flex conductor captive within slots or between plastic framing pieces.
This may allow a better signal connection.
