Still at it

[marshall]

My Hantarex 9110 seems to have lost GREEN, so Ive replaced the transistors on the neck card, fitted a cap kit and replaced the transistors on the main card for the GREEN, but its still the same. So Ive swapped the RED and GREEN wires on the neck card and GREEN has come back, in a fashion, its not as strong as when the RED or BLUE were when turned right up but its definatly there, RED is there but its now weak. Ive read somewhere that there are diodes for the incoming colors which can short causing loss of a color, so my question is which diodes should I be looking at? Whats my next step??

i only have the mtc9000 schem but i think they are almost the same
check,
D2,TR4/5/6 and the resistor around those

[marshall]

Thanks, so I need to change a resisior also?

no check the values with a multimeter/observe the colour coding so they match-no need to change anything unless its faulty

[marshall]

OK thanks.

It was TR 4/5/6 that I changed (GREEN) but will dig out schematic and change the diodes.

and you checked on the neck card the following,
TR202
R204.206.207.208

Have already changed TR 202, but will change the resistors also for what they cost.
