No sound with all the other stuff working is usually the audio amp, U5, TPA2000D1PW.
Wonderful! Thanks GRJ!!!
If you do the search GRJ recommends, there's a great summary post of what to try for the PS2 5V board set.
Buried in that is reference to ChipQuik which is a low-temperature (think "Lead") alloy which I use when removing the SMD audio amp on the PS2 3V board. Everyone has their favorite method for de-soldering but I find ChipQuik useful albeit somewhat expensive. You'd use maybe 1 inch of the stuff to remove the TPA2000D1PW. There are plenty of youtube videos and such to see it in action if you're not familiar with it.
As GGG points out, the heyday of PS2 5V board repair was like 10 years ago. My memory isn't what it used to be but I'm pretty sure I was able to use ChipQuik to separate the 5V board pair. But the question is what exactly do you do once you have the boards separated? Without a definition of the interconnection pins what would you do first? If you only have a few board sets, I'm leaning toward the "lost cause" school of thought. But someone once said that lost causes are the only ones worth fighting for...or something like that! It sounds like GRJ has a box of non-working 5V board sets. If you could get your mitts on some of them for little or no cost, then I'd think it might be worth the effort.
It would be like going back and saying I want to learn how to use a slide ruler again? Sure you can do it, but why? I am telling you that all the components on that board are beyond useful life. Are you going to change every capacitor, diode, FET? It is also multilayer board so do not be surprised if you tear traces you do not have access too.
Stick to the simple stuff. Motor function, Sound, lights? If it starts doing weird stuff, your most likely at the processor which you can't fix or program if you had one.
I have a board right now that starts up after a 15sec delay, but only headlight comes on. No other function. How are you going to fix that?
Everyone has moved on to better functions like quillable whistle, bigger sound files, whistle smoke, rule 17.
If you wanted to concentrate on something, look at the 3V board and start looking at PS-3. Get ahead of the curve:-) G
To all my supporters and replies, I agree with everything said regarding, moving on. It won’t stop me from experimenting, or being curious, but I don’t have any expectations of resurrecting any 5V’s or 3V’s for that matter. Thanks again, I’ll continue to monitor the site, and who knows, maybe I can help someone?
best regards

I wouldn't give up in the 3V boards, they're very repairable. For the ones with only the sound out, I know that both GGG and I have brought a number of those back. Other stuff like speed control issues are usually pretty easy to fix as well.
For the 5V boards, I limit myself to FET replacements for various I/O functions, the audio amplifier, and the one large capacitor that seems to be the most common cap failure. All of these are done without separating the boards.
Thanks GRJ!!!
