Re: Bush TV22 restoration
I have an interesting "cold" fault on this set. On switch on, after a few days of non-use, I get a low brightness, defocused and offset picture with visible masking (see picture). Refocusing in this condition requires the focus lever to be turned hard clockwise. After about a half hour the problem suddenly disappears, reverting to a bright(ish), centred display again with focus back to normal. The fault remains absent on subsequent switch-ons - even after an overnight period, only returning again after a period of a few days. Is this a low EHT problem (I have no meter), possibly moisture related?
