Hello friends, im very confused about resistances in RGB and Sync signals of MVS boards.
I see diferents models of boards have little diferents values to work, like MV1C vs MV1FZS
In CRT TV all works fine at:
--------------------------
RGB = 200 ohm
Sync = 1k - 1,1k
The problem/strange is in a LCD TV:
--------------------------
RGB = 75 ohm
Sync = 1 ohm
In MV1C work fine on 1 ohm, but MV1FZ only adjust at 90% the sync, a little blurry/doubling on horizontal sync remaining, its because it need no resistor or 0 ohm in line? i dont know because minimal range of pot is 1 ohm.
Its very strange because always think LCD screens need values around 4,7k in Sync, but is not the case
Im totally confused.
