I had one of my Boom which decided to have a farting speaker, and as it was also becoming pretty sticky, I did a full cleanup
- 2 re-foamed speakers
- new display
- front panel cleanup (@JoeMuc2009's method of 15 min in 65°C water + @chill's idea of spray coating)
- button full scrub + re-paint
Result is not perfect, but it's not bad. The screen seems to still have some brightness differences between columns, I don't know why (although it looks much worse on picture than it is in reality). This is a Boom where I applied Joe's diode repair, but I took references of the 2 transistors underneath, I'll see if they can be found.
