Hi,
I have a grundig GDS3000 that is failing to get the Horizontal channels (High Volts). Does anyone know of stock faults, or able to provide a diagram for the appropiate part of the circuit.
Regards

Replace ALL the electrolytics in the secondary side of the PSU - you can buy kits that contain them all - or check each one for it's ESR, you will probably find one (or more) that's gone high ESR.
Generally circuits aren't available, the only ones I've ever seen were Pace ones.
