Re: I don't f*cking believe this, my DOJ is dead.
I don't really understand why everyone is telling me to remove that battery. Yes , it can break the board , but it seems that everyone here is having problem a few months after removing the battery ...
Anyone here have a working Ketsui or DOJ board after removing this battery for a long time ? Is there somewhere on the internet where i could buy a new one ?

Re: I don't f*cking believe this, my DOJ is dead.
That thing on the right there is a resistor array and is faulty clearly, it appears to have spread to the other one too. It's a fairly common part so at least that's fixable, has the corrosion spread since then? Could be a reason why your board isn't booting.

Re: I don't f*cking believe this, my DOJ is dead.
Oh , last thing that i forgot , my PCB is still booting on Freeplay , No continu.
Does that mean that , even leaking a bit , the battery is still working ? oO

Nothing to stop you replacing it though.

Should be easy to find, what is marked on the battery in terms of voltage, mAh, etc?Anyone here have a working Ketsui or DOJ board after removing this battery for a long time ? Is there somewhere on the internet where i could buy a new one ?

Re: I don't f*cking believe this, my DOJ is dead.
Thanks
But i was wondering if anyone here already tried to replace this battery ? 


Re: I don't f*cking believe this, my DOJ is dead.
The shelf life on these things is generally only about 5 years so I'd say a high percentage of these boards has had the battery replaced.
If the battery has leaked I'd suggest swapping it out asap. You'll definitely want to clean up the leaked acid too. If you are unsure about doing it yourself I'm sure someone around here wouldn't mind doing it for you, or I can if you want to pay for the new battery.

Re: I don't f*cking believe this, my DOJ is dead.
Many thread pop up on neo arcadia & arcade system as well.
I was wondering "how are mines?" and checked my Ketsui, Esp garuda & DDPDOJ. Results: 1 really melt, the second one just melt and the third one didn't.
I already took off two of them but I will replace all of them. I'm sure board with problems are the melty/exploded ones.
Thank you for your thread mate

Re: I don't f*cking believe this, my DOJ is dead.
Yeah I'm willing to bet those with now faulty boards didn't clean the corrosion after removing their battery.

Re: I don't f*cking believe this, my DOJ is dead.
I guess in your case the damage was done since that resistor array was already dead, it could have lead to further problems over time.
Do you have current pics of the board?

Re: I don't f*cking believe this, my DOJ is dead.
Yeah that corrosion will eat through thin tracks (and big ones) quite easily. Good news is it shouldn't be too hard to repair if that's all it is.

Re: I don't f*cking believe this, my DOJ is dead.
it's not to bad if done right by someone really...can look bad when done badly though.trace it along the track and glue it to the board...and nice green wire to blend in ...anyway it will be in a case no!

<trk>:I remember catching a big fat one and my friend said "throw it back in, that one already tastes like wood"

Re: I don't f*cking believe this, my DOJ is dead.
You can repair the track with a conductive silver track pen, yo.kernow wrote:Would it just be by bridging them with a thin wire? bit of an ugly repair but I guess you can't rebuild the track any way, sadly.

Re: I don't f*cking believe this, my DOJ is dead.
I've got a bad / broken trace on a TMNT board that I'm going to bring. If I flex the board in one spot it works perfectly.

Re: I don't f*cking believe this, my DOJ is dead.
Do you know which track it is? I've had boards with broken tracks that when flexed in one area cause the problem to show up, when in fact the break was elsewhere on the board - ie a very, very TINY amount of flex is sometimes enough.markedkiller78 wrote:I've got a bad / broken trace on a TMNT board that I'm going to bring.

If he can't get it sorted at the meet he's sending it to me. I think. No obligation though.Who is saving your DOJ Kern? I would love to see how you fix these things for future reference

Re: I don't f*cking believe this, my DOJ is dead.
I've no clue what track
I reseated the roms & one pin is totally bent as I though that it was the culprit (when I pushed on it, the board flexed) I'm sure it's something simple tbh, but simple & solder have me stumped

Re: I don't f*cking believe this, my DOJ is dead.
As you have a TMNT board it's worth noting that problems can also occur with the legs on the various surface mounted CPUs, ie they may not be soldered on properly, the chip may have been knocked, flexed badly, etc. This of course applies to all boards with SMT chips, especially the larger ones with very small finely spaced legs (such as Numan Athletics and others of the later era).
