Thanks for this. I couldn't figure out how to get the blue clip off without breaking it to clean some dirt on the screen. Googled it, found this, job done.

Sometimes the activity of the reference quartz is 11,150 MHz, and the devices do not find each other.

I have so repaired the parent module.

Hi Dimitriy - I am experiencing the issue with not finding devices each other. How have you fix it ? Is it a matter of replacing the reference quartz with new one ?

Hi. At my Angelcare (AC401) parent unit the screen has slowly become worse and worse. At first, parts of the temperature figures dissapeared, then the symbols around and now I no longer see anything... But the unit still works! (And alert me if the baby's crying) What do you think, is there anything I can do or do I need to buy a new one?

Hi There. I’m having the same problem. Did you find a fix or did you buy a new unit?

Screen repair:

1. Disassemble according to the above instructions. There is no need to take the screen out of its plastic housing.

2. Position the screen so you can see the ribbon coming to it and its contacts. From now on, the screen should not be moved.

3. Use a hair dryer or similar device and heat the PCB at the spot where the ribbon contact cable is attached to the PCB, leading to the screen. Heat it well enough its hotter than you can touch - the plastic on the nearby condensers and other glues should become soft.

4. The screen shall become transparent when hot, and black when getting colder. Worry not.

5. Use a tool to press the ribbon harder onto the PCB.

6. While at it, press with your fingers also where the ribbon enters the screen, I cannot say on which side of the ribbon your problem lies. Both shall be hot, they’re near.

7. Blow some cold air over it, leave it to cool.

8. Assemble it back to the original Step 4, test.

9. Mine works all but the two lower bargraphs!

10. Else, new PU is 36eur.

Hi there. I am having a problem with the monitor unit. Whenever I connect the power or the breathing monitor. It stops broadcasting. Only on batteries it broadcasts to the parent unit. Parent unit is fine, and the connection is also fine.

PCB have no corrosion due to battery leakage?
