Display screen doesn
I had the same problem here,,,
This was my friend rowing that we received as a "gift" (he wasn't using it anymore) and the LCD display stop working.
Without the user manual, I decided to remove the side panel and by doing so the LCD panel pop out showing the source of the problem...
The AA battery simply felt off inside the case.
So my guess is that either your battery felt off or is dead.
So here're the steps...
1. remove the LCD panel (use a flat screwdriver if needed)
2. if there's no battery, it is probably inside the assembly. You can try to retreive it by removing the 7 screws on one side or simply leave the battery if it's not interfering with the rowing mechanics.
3. if there's a battery, it's probably dead. Change it! Read More At : Lifespan RW1000 Rowing Machine...
