    OK, thank you Patrice. I was just asking because of the bad reputation of the VD1212

    The first thing to do is remove the glue

    I have some Epcos MKP in "my stock", so I've put them in place of the original films caps

    and I've finally changed the electrolitic capacitors

    and that's all for now...

    VD1212 only have a bad reputation because people confuse them with the Sony VD1221 that definitely has a bad reputation.

    Power supply caps. UCCs are exactly the same size as the originals. Epcos are somewhat shorter. Easy to fix.

    New lamps just installed. They are smaller than the originals (3mm vs 4mm), but they will do the trick.

    Thanks! Boards DA/DB and DC 1/2 still needs to be cleaned and recaped. The aluminium parts are going to be anodized this week. I live in Spain.

    To get rid of the scratches, this time I used this:

    And it works really well. Look at this scratched area near the "100w" text
