I’m plodding on slowly.
As the original UHF tuner was iffy I decided to use a replacement from a scraped 1400. As it’s a later tuner I had to do the normal repairs on the presets.
I’m still not happy with the width but I did read on John Laws fault finding guide C114 high voltage cap can affect the width. Also on John (HCS )notes he says if it’s not a disc type to replace it.
Also a new fault now ,I get intermittent frame collapse .im still working on that . Again on Johns notes he says check tags on FOPT they look ok to me. Maybe I will re solder anyway.
Any more help appreciated.
