Beauty! Yet again top notch logical fault finding, a pleasure to watch! Sold a few of these back in the day, although not as many as the Matsui's that used to fly out of my Currys branch week in week out. Lovely little set.
Excellent repair, some plastic weld to fix the cab applied on the inside, Hitachi really made some quality stuff, making the entire crt base and all its components a thick film hybrid was great from the perspective of thermal tracking and reducing drift, not so great if it failed and you needed a new expensive part, they seemed very fond of using those ceramic base thick film jobs generally, always trying to get that last bit of performance and reliability, didn't always follow though, great times.
That takes me back... Grandparents or parents would call and I'd tell dad/grandad to take the back off. Use an old paintbrush and hoover it out as best you can, I'll be around after dinner. "Wow, that was filthy! Is that why it failed?" No, it just means I didnt have to try and find the fault under those years of dust". Of course it backfired when grandad's heavy hand broke the corner of the tube PCB off. Nothing araldite and a few track repairs couldn't fix mind you.
Although it would have been a bit harder to repair a necked CRT with Araldite 😄 . You got lucky that the board broke instead. Once, about 18 years ago I necked a tube as the sleeve of my hoodie got caught by the corner of the neck PCB. It was a nice strong A59-whatever Nokia tube. I was fuming! Fortunately it was mine and I got it for free, but I still was mad about the situation. Ever since then the first thing I do when I work on a CRT TV is to unplug the neck board...
I loved the Hitachi TV sets.Here in the U.S. They had the best tech support in the industry to service centers. Sadly, the head of tech moved up in the company (IIRC) and the support became pretty mediocre. I seldom saw their sets in for service. They were just behind Teknika in set reliability. I remember selling a lot of their sets because of that reliability.

My family bought one when I was 15 in 1983. The remote was beautiful with thin angled channel change buttons.
You have a great collection of service manuals and replacement parts to sort out all the problems. Great job getting it sorted 🇬🇧👍🏻

Remember fitting those psu kits as a 18 yr old apprentice. Nice days..

I remember those wee sets, good times many moons ago
Brill mate, These tvs and the panasonics of this era had one hell of a good picture
Wow this one brings back memories

I fixed many of those back in the day! I think the home computer explosion must have generated some additional sales for portables.
