I have a Toshiba TV, model 24AF41 (flat screen) which has recently started to show interference in the form of horizontal white dotted lines in the top quarter of the screen. Is this likely to be something that can be sorted through judicious use of the service menu or is it more likely to be a symptom of an underlying electronic fault? thanks in advance for any suggestions....
Filter cap going in the vert deflection circuit.
KEEP out of the service menu ,fix the fault.
Why does everbody think that going into service menu,s will fix faults ?

Hi Kip,
I notice from the above thread that you seem to know a fair bit about television repair.
I am repairing a friend's 14" Grundig television and discovered a common power transistor PS fault. I purchased and replaced the kit of components for this fault.
The original 'dead-T.V' fault has now been resolved however, there are now diagonal lines across the screen when using the built-in antenna which disappear when using an external antenna?
Any tips would be greatly appreciated.
Thanks.

Wishful thinking? Maybe seen some suggestions for adjusting vertical size to hide data? If the problem is that the geometry, size, or position is off a bit one could be seeing data in the vertical interval and this might be fixed with service menu adjustments on some sets.

Many thanks. Is this likely to be physically located on the yoke circuitry or could it be anywhere?
Someone she spoke to at the Toshiba service center in New York apparently did. But (typically) the full details weren't written down.
