/vr/ - Retro Games

Anybody knows how to access service menu on one of these? Model is Trinitron kv19-XMB from early 90s, technically PAL region but accepts NTSC input, basically saved it from being smashed by niggers in the street, it was dirty and cord was cut, turns out it works perfectly and the insides are clean. Picture quality is great but using RGB SCART input picture is offset to the left and it's been killing me.
