Default Re: Philips G8 G22K522

Here's what the manual says:-

Tune the receiver to a transmission and adjust the controls for a normal picture. Connect a voltmeter between TP9 and chassis and adjust R2177 for a reading of 6.4 volts. Reconnect the meter to TP8 and adjust L4501 for a reading of 6.9 volts.

The two test points and R2177 are at the rear of the IF panel by the audio output transistor T225. You'll notice a 10uF capacitor C2170 nearby. Although it's a good quality component, it's possible this is faulty.
