Default 2003 Accord ECM/PCM Processor fault

Hello!

I've a problem with my 2003 Accord K24A3. Long story short, went to service for clutch replacement. After the service was done, the engine was turning over but didn't start. My initial thought was that mechanics didn't take out the accumulator before welding some parts on the car, since everything was fine before and as a result cooked the electronics. After half a year decided to look for solutions, connected OBD and found the ECM/PCM Processor fault, code P0606. Called a guy for further diagnostics, but he found the same thing. Told me to take out the board and I should look for a replacement. Upon opening the panels on drivers side, I found a spot of rust on the electronics block. Upon opening the block it was quite clear that the issue was not what I originally thought. I cleaned the schematic carefully with proper electronics cleaner, dried and hooked it up once again. At first the check engine light was gone, drove around the block for 5minutes, everything seems to be great. But it was short lived hapiness, next day, tried to start the car and the engine light was back on. So I took out block again to inspect once more. I found some green leftovers (don't know the english name for it) on one of the pins next to the (main processor?). Tried to inspect all the pins one by one if they are attached to the board and the one with visible damage is moving. I add some pictures. Is it realistically possible to fix it? Can it be soldered back on the board? Thank you!

Get the information off the box. Part number, serial number, dates, whatever you can.
There are companies that can do fix this. However, they aren't cheap and not a guarantee to perform perfect.
You could look for used? Ebay?

The green stuff is verdigris. We call it green death. You would need to neutralize the green death and use a pencil solder iron and hit the pins.
Watch this. This is the same technique you would need to do on that board.

Thank you for replies!
Gave the block to technician and he said that it's not possible to fix it, there is too much damage. Currently looking for a replacement block as I don't know any other solution than getting a new one
