Lovely old tellies,these!
They are very reliable,but of course at this age,your's is probably suffering some dried out caps,and also poor soldering.
The weight of components like transformers and wotnot,put a strain on their soldered connections,which eventually become intermittent.
A "scientific" test would be to (respectfully!)tap the tv cabinet when the fault occurs,to see if this has any effect.If the fault clears,you know it's poor soldering somewhere,and well worth investigating further
As you say,if the picture produced is still good,the set is worth saving,but you will need some help from someone with experience of these.
There isn't a "quick fix" that I could suggest,but from your description,the problem doesn't seem too major.
I have technical info,if you can find a local "old un" Engineer with B&O telly experience to have a look for you?
As to the video recorder,these were remodelled Philips machines,and very good too.The Philips video recording system was argueably the best of the three available at the time,but of course ,overshadowed by the enormous success of VHS,argueably the worst of the three?
Again,expert knowledge of these machines is needed,and sadly rare nowaday's.
Good luck with it all.
Regards,
Nick
