Hello everyone!
I stumbleb upon a problem with my SCPH-1000 Unit - it lost almost all in-game audio, only played crackling sounds. Audio CD works great on the other hand. Reading trough forums I have decided to put in another SPU.I wanted to change CXD2922Q to CXD2925Q. To do this, I sourced a SCPH-1002 board.
After some hot-air soldering I was left with a PU-8 board with no SPU at all and a PU-7 board with a newer revision SPU.
Upon booting the console there was no sound again and I found out that I have some cold joints. I tried to solder them down a bit better with a soldering iron instead of air-station and now it won't do anything at all upon boot. No signal, no audio, no nothing.
The PU-8 board boots perfectly fine even without the SPU chip so i desided to remove it from the PU-7 board again and clean everithing up, however, still - no effect. The console dows nothing upon turning the power on.
Not like i'm that bad on soldering, I inspected the board and cleaned it - no short cicruits that I can see.
What should I do? Maybe there are some blown fuses on the board somewhere?

Fuses? Pinouts should be as so https://problemkaputt.de/psxspx-pinouts-spu-pinouts.htm check for yourself if the 3.5V and 5V supplies are there. But be careful that you won't shortcut the supply pins while powered on.
