R: Cine Monitor problem

Done.
THe problem (attached picture P301111_...) was on the sound board: a
defective tantalyum capacitor on 7815 regulator. At the moment I changed it
with an electrolytic one (on the right of TL182 in the attached picture
SP_A0255)

  Is it jittering or is it a stable screwed up image? If it's jittering,
look for ripple on one of the power supply lines.

    Hi All,
    some days ago my star hawk bagan to have the problem shown in the
picture. I swapped PCB with a speed freak but the problem was still there,
so it is a monitor problem.
    I already changed all on board regulators (78/7915,78/7918) and all four
TO3 transistors but nothing changed. lf133331 had been substituted with
another one too.
    Do you have any idea?

    regards,
    Marco
