one of these came in for recycling a while back.the shop helper kid wanted it so we looked into fixing it.had a dead external brick psu.you guessed it.bad caps.fixed that and it worked.recently he reported an occasional flicker.got inside and found a 220@16 near the +3.3 reg open.the others were 100@16 and were marginal esr.
replaced them and flicker gone.
