I've just taken the power board out of my TZ to replace the GI header pins which are burned out, and noticed that two of the five big 15000mF capacitors are very slightly domed at the top while the other three are pretty flat. As I understand it when the tops dome then the capacitors have usually had it, but the board is working fine. So should I replace the domed ones or leave them be on the grounds that if it aint broke don't fix it?
