Default Re: Help with a HMV TV

Reading over this thread again a few thoughts come to mind.
The Line Out stage is trying to operate but seems to have issues with its operating conditions.
As a start, confirm the voltage on the 6CM5 cathode and screen. These will establish that at least this area is operating correctly and the valve isn't overloaded.
Next, have you tried a replacement 6AL3 damper diode?
Check all connections are correct around the width coil and horizontal linearity coils, someone may have messed about with this area. Ensure all components connected to the boost volts supply are tested or confirmed as working. A leaky capacitor or resistor thats gone high can cause issues here.
