[QUOTE="Llew, post: 172694, member: 175007"] Sorry, haven't got a circuit board layout, but here's the schematic of the chroma IC, with the trimmer that can be adjusted. Just a question of finding it on the board! As with any equipment with high voltages floating around, it is imperative that you make any adjustments with the TV switched off unless you are confident (that's my get-out clause :) ) - and that the trimmer adjustment will be [I]very[/I]small.
