The manual was complete, parts list, adjustment procedures, etc. No worries
 ;
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.
5-11. VPP sensor circuit
Protection circuit
To prevent the circuit breakage, the protection circuit watches the voltage level of VCC, VDD and VPP. When the each voltage level is more than following condition, this circuit cuts the voltage. VCC,VDD: In case these voltages are become over voltage, this circuit outputs �SCR� signal(High signal) and burn out the fuse. In case the VPP voltage is more than 15 V or less than 13.9 V, the �VPP.S� level is inverted and CPU cut the �VPP.ON� signal.
VPP:
Detection voltage level (Unit: V) VCC >= +6.5 V VDD >= +6.5 V +13.9 V =< VPP <=15.0 V
5-12.Power supply circuit for display
VC VP GND
This circuit is making the power for display tube. Voltage level: -VN VF1 - VF2 Est. -31.2 V Est. AC4.85 V
