Symptoms:

- Initially, a white LED was fading/cycling on and off.

- Now, there is no LED light at all and no response to button presses.

- The screen is 'frozen' on the last book cover I was reading.

- The device is not recognized by my Mac.

Steps already tried:

- Multiple 30-40 second power button holds (both while plugged in and unplugged).

- Manual factory reset attempts using the Page Turn + Power button combination.

- Physically opened the device and disconnected the battery.

- Performed a 60-second power button hold with the battery disconnected to drain residual power.

- Cleaned the white interconnect ribbon cable and confirmed it is seated correctly on both the motherboard and power button board side.

- Attempted to 'auto-boot' by plugging into a Mac with the battery disconnected (no response).

- Verified the motherboard button bracket is present.

I'm concerned the deep discharge followed by a 17W charge attempt may have 'latched' the power management IC or that the battery has dropped below a recovery threshold. Is there a known way to force a boot or reset the charging controller on this specific model?

I need to repair my Kobo Libra Color which it cannot charge nor boot up

⟐ Commented maio 17, 2026 at 20:02 GMT-7

My Kobo Colour Libra has been stuck on a book cover page, being unresponsive to anh touch or button response. I tried charging it, but the charge light usually does not.come on (only sometimes, but most of the time it does not indicate that it is charging). I am also unable to switch it on/off or restart it.

My kobo's warranty has sadly expired. Please do help me in this, thank you!

My Kobo has this weird scratches and I don't know what to get in order to fix it. I can clearly see the words in light mood but it's textured and blurry, looks like the film piece came of and allowing the light to strike through the scratches ever since I got it.

I need help to know whether you think the screen is broken and I should buy a replacement and repair it, or if it could be a software issue.

I haven’t dropped it or hit it, but it was inside my backpack.

Thank you very much!

I need help troubleshooting my Kobo Libra Colour e-reader. It's completely stuck on the "Please recharge" screen and won't respond, even after trying multiple fixes including a brand-new battery. The white LED charging indicator lights up, but the screen never changes.

What I've Tried So Far:

• Multiple wall chargers (5V/2A) and USB-C cables (known good ones)
• Charging undisturbed for 24-48+ hours on both old and new batteries
• Soft reset: Power button held 20-30 seconds (LED blinks)
• Manual/factory reset: Page turn button + power button held 30 seconds while charging
• Battery cycling (unplug/replug 20+ times while charger connected)
• Inspected USB-C port (clean, no visible damage)
• Verified new battery connector fully seated, correct model/compatible replacement

Current Symptoms (Same with Both Batteries):

• White LED illuminates when charging
• Screen stays frozen on "Please recharge" - no progress, no boot
• Not recognized by PC (no drive mount)
• No response to any button combinations

Theory: Suspect charging controller, display driver, motherboard, or firmware brick. Battery swap ruled out power issue since symptoms identical.

Questions:

1. Anyone fixed this exact "dead screen but LED works" issue on Libra Colour?
2. Could it be the battery management system (BMS) needs special reset?
3. Mainboard replacement viable?
4. JTAG/short-to-reboot possible, or is it bricked?
5. Kobo support dead-end?

I recently used iFixit parts/tools to repair my Kobo eReader, and after the repair the device is not working correctly. I would like to ask for assistance.

• Product(s) purchased: Kobo Libra Colour Screen Assembly - Genuine
• Purchase date: 18 Nov 2025

Issue description:
After installing the replacement part(s) following the iFixit guide, the Kobo eReader powers on but remains stuck on the “Welcome to Kobo” screen and does not respond to touch. The device cannot proceed to the setup or home screen.

Steps taken:

• Rechecked the internal connections and reseated all relevant cables
• Fully charged the device
• Tried forced restart and manual reset according to Kobo’s instructions

The problem still persists.

Could you please advise:

1. Whether this behaviour could indicate a defective replacement part or a known compatibility issue.
2. Whether the repair part you provide is adaptable for my motherboard…as you haven’t mentioned and give me the choice before I place the order..
3. What diagnostic steps you recommend to confirm if the part is faulty.
4. Whether a replacement or refund is possible for the part if it is determined to be defective, and how to proceed with RMA from Hong Kong.

I can provide detailed photos of the installation and a short video showing the issue if required.

Thank you for your help, and I look forward to your reply.

It has no response to button click or screen touch.

I tried the press and hold the power button. It does not power off. it shows "Sleeping" in screen.

I also tried connect it to charge cable. and no response as well.

Can this issue be fixed? and how?

thannks

I haven’t used or charged the device for a few months. Now the screen shows it is on sleep mode but it cannot be charged.

I have tried to connect it to a USB charge port, power bank and a laptop but none could charge it up. I have also tried to switch it off by pressing the power button but got no response.

Is it a problem with the battery or the motherboard?

Thank you.

That leads to 2 questions:

1. do I have to change, after switching screeens, the VCOM of my device to "-1450"?
2. Or, since the orginal SCREEN had the same VCOM number as the REPLACEMENT screen, I do not have to change VCOM on the device?
