fixed my cpc, help with my gt65 monitor please

[davetheshrew]

my gt65 monitor seems to have an issue, with v.hold especially, when the cpc464 turns on it looks like I have a blank screen, but if I scroll the vhold wheel I can just about manage to get the amstrad basic stuff peeking at the bottom of the screen. Is there a way to get it so my screen can go up a bit more so I can see everything? Could it be capacitors or something?


when the monitor came through the post it took a hard slap and cracked the case in transit, maybe something shifted?


thanks

Does the CPC464 work on an other monitor ?

Ive not tried another monitor but I connected a rca plug to gnd and luma and got a good picture in bw.


Ive got decent tools and know how to protect myself, Ive figured out that potentiometer  vr702 manages the vhold but even if I crank it to the maximum I get 1/3rd of the screen at most and its not stable. Is there schematics around? will start looking
