Then does that mean the bad cap is in the vertical circuit area? I capped my DK when I first got it and although it wasnt a complete kit, (cheap-ass ebay kit...) it seemed to do the job until recently. I am seeing vertical jail bars again.
I would bet yes there are more caps needed. New components cause stress on the old. I'd order a kit from Zanen, Lizardlick or Mikesarcade and replace everything again to be on the safe side.
I am working on a list to help me determine which cap causes which failure on a Sanyo 20 EZV. (Just for my own record) But to be honest, your better off doin' 'em all as Deadly suggested. I think it's a total of 30 (including the sound bd) but Bob Roberts deluxe kit should be good.
C459 100uf 16VDC. Horizontal tearing. Looks as if you should be able to
adjust it out with the horizontal hold control but you can't. May cause
multiple images.
