One morning, I made coffee and grabbed the baby monitor. But it didn’t turn on. I pressed the power button over and over. Nothing. A red light came on, but the screen stayed black.
I felt stressed. As a parent, silence from the monitor can feel scary. So I started trying different things to fix it. I reset it, changed the battery, and even used a pen spring. Finally, I found something that worked.
In this post, I’ll show you what I did. You might be able to fix your monitor too.
Why Your Infant Optics Monitor Won’t Turn On

Don’t panic. There are a few common reasons:
- The battery is dead.
- The charger is broken.
- The power port is dirty.
- A part inside the monitor is loose.
Quick tip: A dead battery, bad charger, or loose part is often the problem.
What the Red Light Means
If the red light is on but the screen is off, the monitor is getting some power—but not enough. It may be stuck in between on and off.
Quick tip: A red light with no screen often means a weak battery or a stuck power button.
Signs It’s Not Charging;
Sometimes the monitor won’t charge at all. Here are some signs:
The charging icon does not show.
The red light blinks or stays on.
The screen stays black.
Quick tip: No charging icon or a blinking light means power issues.
My Story: What I Did to Fix It
It was a normal morning. I picked up the monitor. Nothing. Just a red light. I thought it needed to charge, but that didn’t work.
I tried everything—resetting it, swapping cables, waiting. Still dead. I almost gave up, but I kept going. And I’m glad I did.
Fixes That Worked for Me
Let me show you what finally helped.
1. Power Cycle the Monitor
Take out the battery. Wait 20–30 minutes. Then try to turn it on.
First, I unplugged the monitor. I took the battery out. I waited. Then I plugged it in without the battery. Nothing. So I put the battery back in. This time—it turned on!
Quick tip: Remove the battery, wait 30 minutes, and try again.

2. Check the Charging Cable and Port
My charger looked fine, but it was broken inside. I tried a different cable I knew worked. The charging light came on!
I also cleaned the charging port with a toothpick. Dust can block the connection.
Quick tip: Try another charger and clean the port with care.

3. Check the Battery Connection
I opened the back. The battery connector was loose. I used a pen to push it in gently. It clicked—and the light got brighter!
If you see green marks, clean it with rubbing alcohol.
Quick tip: Press the battery connector in and check for dirt or rust.
4. Replace the Battery
Old batteries stop working. Mine was swollen a little. I bought a new one online. This is the one I used and it worked perfectly. After I put it in, the monitor turned on right away.
Quick tip: If the battery is old, try a new one.
If It Still Won’t Turn On — Try This
One day, I saw a video where someone fixed their monitor with a spring. I tried it too.
I opened the back. I took a small spring from a pen. I placed it behind the power button. This helped the button “click” again.
When I pressed it—the monitor turned on!
Quick tip: If the button feels soft, a pen spring can help bring it back to life.

Only try this if you’re okay opening the monitor. If it’s still under warranty, skip this step.
When to Replace the Monitor
Sometimes, nothing works. My first DXR-8 lasted about two years. One day it just stopped. New battery, new cable—nothing helped.
That’s when I knew the inside parts had failed.
Quick tip: If nothing helps, the main board or screen may be dead.

How Long Should Your Monitor Last?
From my experience, the battery starts getting weak after 12–18 months. After two years, you may start seeing more problems.
If you’ve tried everything and it still won’t turn on, it might be time for a new one.
