Very usefully, I could find the trouble clearly with that manual.
;
Bon produit. Permet de corriger les couleurs et de redonnez un petit coup de jeune à vos vieilles vidéos. On regrettera juste le manque d'une prise s-vidéo.
 ;
Quality scan of the actual service manual, just what I was looking for.
;
Straightforward ordering process. Service manual scan was clear & easy to read. Very comprehensive instructions for alignment. Excellent, thank you.
;
Fast, clear and useful. Important for me: the manual is in German.
