Picture guide of CD-i battery repair

>> Monday, March 23, 2009

We've come a long way with different members who tries to repair the CD-i timekeeper battery; you may remember Terratron's repair guide and some additional tips given on Interactive Dreams, but the whole procedure remained difficult. Now CD-i member "nrg78" made a full picture guide, see below which might help you through the process if you want to extend the life of your CD-i player!

Comments by "nrg78": "After opening the case, looking for the IC... initial cut with a sharp blade, then started peeling... second layer, not hard as a normal IC would be, so started scrapping... battery shows up, when I managed to get the MINUS plate away from the old battery, I decided to try and solder the PLUS wire directly on the battery, but the solder didn't stay, so I kept on scrapping until i've managed to pop the battery out, revealing the PLUS connect plate... kept on scrapping until reveall the elsewhere so called "wires", and soldered my wires there."

Thanks to: nrg78

I guess you should just add a note like:

"if your player works just find, but simply does not save scores nor FTS's, then think about the option of NOT DOING this, because sometimes this surgery ends badly... Consider the risk of having to buy a new TimeKeeper IC or even a new player.."

Next week I'll see if a new chip will do the trick in my case. Hopefully it will! =)

I've a problem with my player. During power up it displays CD-i and then "---". When I insert any kind of CD, even normal music CD discs it does not play. What could be the problem?

Bas April 9, 2009 at 3:38 PM  

the battery can be empty, or the disc might be dirty? does the OS shop up when you start?

Anonymous,  April 11, 2009 at 2:03 PM  

The Os shows up when I turn on the power button. It displays the Philips CD-i logo and the 2 icons at the bottom but doesn't do pretty much after that. The Cd's are working fine on my DVD player and discman or any other player for that matter. FYI mine is a Philips CD-i 220 model.

Bas April 14, 2009 at 9:22 AM  

~does it happen when the player tries to access the digital video cartridge? Or does it also happen with base-case titles? I don't know what happens here, but maybe with the help of other people you may find a solution..?

I have no Digital Video Cartridge installed on my player and what is a base case title?

Bas April 14, 2009 at 11:11 AM  

a base case title is a CD-i title which does not require a Digital Video Cartridge. I'm not sure if a CD-i player still boots when the battery is empty.

retromangia,  April 27, 2009 at 3:46 PM  

Hey guys, I have a 220 also which does not work. I get an "error" message when i turn it on, and no picture or sound at all. I also have the DV cartridge installed.

Any ideas how to fix this.. think it could be the battery?

I bought three Timekeeper Chips from a Company in China. It seems all three chips have non-working batteries. I'm guessing the chips have been laying around for years and are now defective. Does anyone know where to get fresh Timekeeper Chips ??

You might damage your system changing the time keeper
the chips are almost all ancient
I cut out my battery and installed a new cr2032 socket and battery
It was not terribly hard, i would try that before removing the entire chip

I've done this mod today and it works prfectly. Thank you very much. My 450 is now as new.

Anonymous,  January 20, 2011 at 7:52 AM  

The battery that is originally used in the timekeeper is a BR1225 lithium cell rated at 3VDC and 48 mAh.

Using a battery holder for a CR2032 means you will be using a battery rated at 3 VDC at 230 mAh.

Considering that the original battery may last around 10-15 years, the 230 mAh from the CR2032 cell will last for a VERY long time.

Chances are this may be the last battery you'd need to change in your CDi with this modification.

I have performed this mod with my Magnavox CDI-200 and my Philips CDI-220, both successfully.

dorwena777 on Ebay repairs CDI players.

dorwena777 SCAMS,  December 28, 2011 at 3:23 AM  

Don't let dorwena777 do anything to your CDI!!! He will swap parts off yours if you have something he needs and send the thing back to you with bunk parts in its place. This a-hole runs a CDI chopshop thats suspect at best!

There is a seller on Ebay dorwena777 that repairs the Timekeeper Problem.

Anonymous,  October 6, 2012 at 6:44 PM  

I have been dealing with dorwena777 on Ebay for several years. They are honest reliable sellers and repair people. Other sellers are posting negative statements to slander this seller and for their own profit. Just check their feedback !!

I made a video guide/work log of this process. Hope someone will find it useful its pretty hard!
Here you go:

I was thinking a long time of doing this modification for my Philips CDi 220/39 Matchline by myself.
I feared destroying the machine but finally got my hands on a Dremel and startet scratching.
It was surprisingly well working and now the little basterd is like new.
I saved The 7th Guest yesterday and the data is still there! So I guess I just did it right :-)

What I was wondering about is that the display still shows "- - - - -" after starting the OS. Is that normal behaviour?

dorwena777 steals components from the systems they repair. Beware.

Tyler June 20, 2016 at 3:57 AM  

I've been hoping to go this route with my 220, but I've managed to peel away the entire top layer of the timekeeper chip. I have a resource in my area that claims to have this timekeeper replacement part, but I was hoping I could forego further, and more invasive, surgery.
I wonder if it's worth trying to solder at this point?

On the 220:
Front of the CD-i is left:
Front is right:


Tyler July 16, 2016 at 4:49 AM  

I was in the process of trying this modification, when I pulled the upper half of the timekeeper too far and ended up pulling the entire top off. Am I still safe to continue chipping away to access the contacts, or have I ruined it?

There's a place not far from where I am that apparently stocks these timekeepers. You Do It Electronics of Needham, MA.

Be well!

2017 and I've had my CD-i for a few years. It arrived with dead battery from an eBay purchase and never wanted to dare try this (because I'm awful at this stuff).

Made it to the last dungeon of Zelda's Adventure and got a dirty disc error, all progress gone! That was the final straw.

Found this guide, painstakingly stabbed, scraped, and Dremel'd my way through the stupid battery encasing. Ripped it out, ripped battery and holder from and old PC mobo, soldered it into the CD-i with horrible skill, and turned it on...


Thanks so much for this guide, now I can go through Zelda ALL OVER again (so BAD) and finally beat and be rid of this game forever, now that dirty disc can't stop me.

Good luck to all those in the future!

Would it not be safer to install a new chip? Perhaps even in a socket now that we are modding the system. This way, it will be easy to pop in a new chip if it fails in the future...

The timekeeper-chip is this one, right?

I just had Dorwena777 repair my CD-I through ebay. I shipped it off to him, he fixed up my CD-I (including hammering out a dent in the corner to make it look like new, and installed a new belt so the tray opens and closes like new), AND put a brand new battery in there for me. Then he shipped it back to me real quick, like 2 day priority or somethin. I was amazed. Seriously, this guy legit fixed up my cdi and I'm now enjoying Voyeur 2, 7th Guest and a rackload of other great cdi games i never got to play as a kid. Couldn't be happier. So if anyone wants to get their cdi fixed, I say get in touch with him. I did and I am glad I did. He really is like the only person out there who offers a service to fix cdi's. Nobody else does. Sure, there are plenty of youtube videos on how to do it yourself, but for most people like me who aren't technically inclined, we would much rather have someone who knows what they are doing do it for them.

Tried this on my 450, cut the minimum off as possible, dug down, got the battery out soldered a new battery in a socket to the connections, still doesn't keep the time and loses saves and scores when turned off for more than a few seconds.

Thinking next step is replacing the chip entirely.

RS have 333 M48T08-150PC1 chips in stock for £20 each. They can't be selling old duff chips with that amoount of stock can they?
