The Concept2 rowing machine is one of the most reliable pieces of fitness equipment ever built, but when the PM5 Performance Monitor refuses to turn on, your workout stops cold. Whether your monitor is completely dead, flickering, or just showing a [blank screen](/blog/sole-elliptical-display-console-problem-in-dallas-why-your-screen-goes-dead-and-what-to-do-about-it) mid-row, this is one of the more common service calls we get on [Concept2 machines across Dallas Fort Worth](/blog/concept2-rowing-machine-seat-rollers-worn-and-sticking-in-dallas-whats-causing-it-and-how-to-fix-it). The good news is that most PM5 power failures come down to a handful of well-known causes, and most are fixable without replacing the entire monitor.
Common Symptoms
- Completely blank screen: The PM5 shows nothing at all when you sit down and begin rowing, even after several strokes.
- Monitor powers on briefly then shuts off: The [screen flashes the Concept2](/blog/peloton-bike-screen-frozen-on-startup-logo-in-dallas-whats-really-going-on-and-how-to-fix-it) logo or shows partial data, then goes dark within seconds.
- No response to the power button: Pressing the center button does nothing, even with fresh batteries installed.
- Monitor works plugged in but not on batteries: The PM5 only functions when connected to a USB power source, indicating a battery contact or power circuit issue.
- Dim or faded display: The screen is barely visible, especially in bright light, suggesting a backlight or power delivery problem.
- Intermittent power loss during a workout: The monitor cuts out randomly mid-session, then comes back on its own after a few strokes.
- Error codes on startup: The PM5 briefly illuminates and displays an error before shutting down again.
Root Causes: What Is Actually Happening
- Dead or incorrectly installed batteries: The PM5 runs on four AA batteries housed in a compartment on the back of the monitor. Concept2 specifies alkaline batteries, and using old, mixed, or rechargeable batteries is one of the most common reasons the monitor will not power on. Corroded battery contacts from old leaking batteries will also prevent any power from reaching the monitor's internal circuit board. When we open up a non-starting PM5, corroded contacts are the first thing we check.
- Faulty or dirty battery contact springs: Even with fresh batteries, bent or oxidized contact springs inside the battery compartment can break the circuit. The springs lose tension over time, especially on machines that see heavy daily use. A quick cleaning with a contact cleaner and reshaping the springs often restores power without any parts replacement.
- Damaged PM5 internal power circuit: The PM5 monitor contains a dedicated power management circuit on its main board. If the machine has been stored in a humid garage or exposed to moisture, this board can develop corrosion or component failure that prevents the monitor from initializing. This is more common in Dallas Fort Worth homes where equipment sits in garages through hot, humid summers.
- Broken or loose monitor cable connection: The PM5 connects to the rowing machine frame via a coiled cable that carries both the signal from the flywheel reed switch and, in some configurations, supplemental power. If this cable is frayed, pinched under the seat rail, or has a broken connector, the monitor may receive no signal and fail to wake up. We see this frequently on Model D and Model E machines that have been moved or reassembled multiple times.
- Failed reed switch or flywheel magnet: The PM5 wakes up by detecting the magnetic pulse from the flywheel reed switch as you begin rowing. If the reed switch has failed or the magnet on the flywheel has shifted position, the monitor never receives the trigger signal to power on. The machine will feel normal to row, but the PM5 stays dark. This requires checking the reed switch gap and continuity with a multimeter.
- Firmware or internal memory fault: In rare cases, a corrupted firmware state can cause the PM5 to fail its startup sequence. Concept2 does provide firmware update tools and a reset procedure that can recover the monitor without hardware replacement. This is something we handle in the field when all the physical components check out fine.
What NOT to Do
- Do not force the monitor off the mount to inspect it yourself: The PM5 attaches to the monitor arm with a specific locking mechanism, and prying it off without releasing the tab correctly cracks the housing. A cracked housing means a full monitor replacement, which costs significantly more than a service call.
- Do not use rechargeable batteries as a first test: Rechargeable AA batteries typically output 1.2 volts instead of the 1.5 volts of alkaline batteries. The PM5 power circuit is sensitive to this difference, and using rechargeables can make it appear the monitor is faulty when the real issue is just insufficient voltage.
- Do not spray lubricant into the battery compartment or monitor housing: Some people try WD-40 or similar sprays on corroded contacts. This leaves a residue that attracts more debris and can short the contacts inside the compartment. Use proper electrical contact cleaner only.
- Do not assume the monitor needs full replacement before diagnosing the cable and reed switch: A new PM5 monitor costs over two hundred dollars. In the majority of cases we see in the field, the monitor itself is fine and the problem is the cable, the reed switch, or the battery contacts. Replacing the monitor without proper diagnosis is an expensive mistake.

Frequently Asked Questions
Can I fix the PM5 myself if it just needs new batteries?
Yes, if the issue is simply dead batteries, that is a straightforward swap. Open the battery compartment on the back of the PM5, install four fresh alkaline AA batteries, and try rowing a few strokes to trigger the wake signal. If the contacts look corroded, a cotton swab with isopropyl alcohol can clean them up. If the monitor still does not power on after that, the problem is deeper and worth having a technician look at before you spend money on parts.
How do I know if it is the reed switch and not the monitor itself?
One way to check is to connect the PM5 to a USB power source using a standard cable. If the monitor powers on and displays the main screen when plugged in via USB but goes dark when you row without USB power, the issue is likely in the battery circuit or contacts. If it does not respond to USB power either, the internal board or the monitor itself is the more likely culprit. Checking the reed switch properly requires a multimeter and knowing the correct gap spec, which is something we handle during a standard diagnostic visit.
Is it worth repairing a Concept2 PM5 or should I just replace the monitor?
In most cases, repair is the right call. Concept2 machines are built to last decades, and the PM5 monitor is a solid piece of hardware. If the issue is a reed switch, a cable, or corroded contacts, repair costs a fraction of a new monitor. Even if the monitor board itself needs service, it is worth getting a proper diagnosis first. We have seen plenty of PM5 monitors written off as dead that came back to life once the real cause was identified and corrected.
