After over one month, DW6k is working again. Yay! Fortunately only the main CPU was broken and after quick (sorta) replacement, everything seems to work just fine. It took so long, because I have ordered the ICs from China and they stuck at customs.
The replacement took longer than I expected, mostly because I wanted to install the IC in a machined socket (you know, just in case), but I couldn't fit all the pins at once, so after more than one hour long struggle, I have soldered the chip directly to the PCB.
For safety's sake I have poured a ton of hot snot on all exposed mains connectors :)
After replacing the fuse I have connected the board to the PSU, powered it on and... success! It blinks again.
Another few moments later I have connected other boards and it looks like this lil one is tougher than I thought - works like back in the day.
More to come soon...
