PHILIPS	2A	Sound crackling - even if eht lead disconnect	C2618 ( 1.5nf )
PHILIPS	2A	Sops radiation	During later production of the 2a chassis, two changes were introduced to reduce radiation from the sops power supply and also to limit the dissipation in ts7687. component position change code no. 2n7 capacitor c2694
PHILIPS	2A	Slow start up	R3670 33r high or oc
PHILIPS	2A	Shuting down with a whine.	Drys on c2609.
PHILIPS	2A	Set ticks in stby	C2690 1uf 100v
PHILIPS	2A	Set ticking in stand by.	Check/replace c2690 - 1uf 100 volt non-polarised. r3689 - 39Ω of pin 8 of sops transformer. d6689 - 1n4148 diode (4822 130 30621).
PHILIPS	2A	Set cuts out int . then just buzzes	D6699 or d6700 6v8
PHILIPS	2A	Repeat failure of line op. transistor	Check line drive transformer for dries
PHILIPS	2A	Raster - low brightness & hanover blinds.	Ic tda3561a.
PHILIPS	2A	Poor ht reg - chopper tr overheats & may fail	D6663 world14k
PHILIPS	2A	Picture looked like a mosaic	Tda3561 us
PHILIPS	2A	Pic on some chans alternates between pic & snow	Ok on scart i/p - 1µ 50v cap in tuner hi esr
