Philips	CP110	hissing sound	chopper transformer replaced	14-09-2004
Philips	CP110	HT volts low at 60 - 70v instead of 140v	C2661 2200µ o/c in chopper control network	14-09-2004
Philips	CP110	Hum in standby; no sound after a while because IC7101 gets too hot	Capacitor 2113 (470uf 35V; 4822 124 41334) goes leaky/short circuit	14-09-2004
Philips	CP110	IC7260 changed type	IC7260 changed type ------------------- A production change has been introduced changing IC7260 from TDA3562/N5 to TDA3566/N5. At the same time R3292, R3293 and T7267 are deleted. Receivers concerned are date coded QG12940 and later. Reason: Alterna	14-09-2004
Philips	CP110	Initially no picture; low contrast picture after some minutes.	Check to see if T7672 is conducting when the fault is present. If it is check for ripple on 140 volt HT line. If a ripple is present, check/replace C2670 (4822 124 80494) and 2621 (4822 124 80494).	14-09-2004
