Just replaced the 3 capacitors. It’s interesting to note that yes there were 2 - 470uf 35 v but the other one was a 220 uf 35 volt and not a 68 uf. Just saying.
I should have taken the board out and looked but I didn’t and it cost me an extra $12 for shipping and handling for second 90 cent order of 2 220uf 35 v capacitors.
Anyway, although the dim display on the SC302ZP improved about 25% I’m not happy with the results.
