Last week I attempted to replace the battery in the Timekeeper chip on my Philips CD-I 210/25. It wasn't really bothering me, but thought I'd give it a go. I was being very careful, chiseling away at the chip whilst still soldered into the board and the inevitable happened - I slipped and hit the motherboard! Ended up severing 4 traces on the motherboard, my Philips CD-I was dead!!! Not easy traces to repair either as they are quite small and close together.
Fast forward to today, I suddenly felt confident and decided to have a go at running some jumper wires to bypass the 4 damaged traces. Bare in mind I've NEVER tried this before in my life and had only watched hours of YouTube videos on the subject, never attempting it myself.
I spent hours following the damaged traces either side, to find out where they all went and scratched off some of the solder mask either side of the breaks for continuity testing with my multimeter. 1 of the traces went directly to 1 of the chips. I fed the jumper wires through and then on the underside of the motherboard I scratched away a bit of the solder mask, applied some flux and then soldered the cables into place. For the 1 wire going to the chip, I decided to simply solder it onto the leg of the chip and add some hot glue to stop it flexing.
I also added some clear nail varnish to seal the damaged and exposed traces.
First power on and it lives again!
And a picture of my handy work, not the neatest job in the world, but it works. I'm quite pleased with myself for the first ever attempt at this kind of work!
I think I'll leave the timekeeper chip in it's present state, not going to tempt fate. 🤣
