Not cabbage | Make sure that the tda3561a is a philips type and not a telefunken type the tfk ones do not work for some reason. try overriding the colour killer by connecting pin 6 to 12v rail via a 470Ω resistor. if the reference is off check components around pins 23-26 inclusive. also check c2282 and c2283 (pins 4 & 2 respectively) c2281 may also have dried out.make absolutely certain that the sandcastle pulse is ok. many odd faults can be caused by this not being quite right. if possible change the tda2579 sync chip (it's in the if can). this also brings into question the line phasing. this is also an adjustment in the if can. r3055 is the line hold. r3038 is the line phase. these pots may not be easy to get to in situ but i would try giving both of them a tweak as they will affect the reference oscillator. |
