Default Re: Pye CT205 - a partial success story!

Good convergence can be obtained using Test Card "F" in black and white if crosshatch generators etc are not to hand. Obviously for optimum results a crosshatch is needed. There's a DVD out, titled "Test Patterns" that was advertised in "Television" a few years ago which includes crosshatch etc.

A strange fault, co-incidentally on a Pye hybrid set(!) was trapezium distortion on the blue gun only. A wire from the scan coils was found to have broken off at the connector to the main PCB!

Excellent pictures allowing for the convergence errors! Well done!
