People like you Micheal should be awarded for your contribution to keeping things from landfill and repurposing well done again loving the work I can't see much but I do understand completed by carer

[@IansMusical]

Thanks Michael, you just sent me on a nostalgia trip to try and find my first Hitachi TV, which served me well and was paired with my ZX Spectrum. The model was CPT1492.

I remember having one of these in for repair, which turned out to be the STR6020 that was the culprit. I remember putting it on a soak test, and after a couple of hours, I thought it was time to put the cover back on when there was a sudden squealing noise and smoke began pouring from the focus unit on the LOPT. My heart sank...... I miss those good old days.

[@marksntl7632]

Most Excellent! Thanks for sharing! I remember working on those back in the days. And the various later built under licence, other branded, variants that looked the same inside and out, when Hitachi moved on to their new chassis. Those Jaeger data and equivelents books were absolutely brilliant back in the days. They saved so much time in finding a realy good equivelent so quickly.

[@jimmacdonald9746]

You have a great collection of service manuals and replacement parts to sort out all the problems. Great job getting it sorted 🇬🇧👍🏻

My family bought one when I was 15 in 1983. The remote was beautiful with thin angled channel change buttons.

[@michaeldranfield7140]

I have one of those as well but the front cabinet has been near something very hot and melted.

I have a GEC branded 16" Hitachi set around the same age, pulled out of a skip some years ago, it just worked once I fitted a plug to it! It must had very little use, as tube tested as new, like yours, the volume pot was perfect, has an amazing sharp picture.

[@roberthorwat6747]

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.

Lovely Job Michael Great Little Sets I Just Changed The STR And Most Of The Time This Fixed It No Bloody Led Strips To Worry About 😂😂😂 Regards mike.

[@herbiescruff5708]

If I remember... The Hitachi named Instaview TVs with their short lived CRTs were rebranded Instavision whose tubes were more reliable. Nice to see one of these 1471s again. Serviced quite a few of those back in the day.

[@f.k.burnham8491]

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.

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

[@stanpatterson5033]

I burst out laughing when you showed the can of flux remover. Might have been the product's brand-name that set me off. Fond memories of CRT televisions. Growing up, my Grandfather bought a beautiful 26'' floor model in 1974, I think it was. It was their first color TV (that I'm aware of) replacing their Electrohome floor model b&w. Cabinet televisions that were actually a piece of furniture. The Electrohome had a cabinet that closely matched a lot of the finer furniture that they had in the living room. French Provincial, I believe it was called. Anyways, moving a bit forward in time, my parents bought (our first) color TV around '76, maybe '77. It was a Sears brand. Sears was an American (and Canadian) catalog order and department store. This 19'' thing they bought, was branded as Sears, but later on, when it warranted some attention, a much younger self ventured inside to see about making some adjustments, and looking for signs of trouble. Imagine my surprise to see a Hitachi picture tube, and various bits with the Hitachi markings on it. I guess somebody's gotta make it for Sears. Anyways, for something that was full of vacuum tubes, I have to say that that 19'' thing had THE best picture I have ever seen of any CRT television. As time passed, it seemed harder and harder to find Hitachi-brand televisions. Oh, they were popular throughout the '70's, and into the '80's, but then they seemed to slowly fade away. With flat screen TV's now, I don't think Hitachi has been making televisions for some time, not sure if Panasonic has stopped making them, too, but nobody in Canada sells them that I know of.

Brill mate, These tvs and the panasonics of this era had one hell of a good picture

[@glpilpi6209]

Excellent , as you say probably had very little use and was put to one side when lines appeared at the top of the screen.

[@georgeprout42]

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.

[@mrnmrn1]

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...

[@monteceitomoocher]

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.

[@peterferguson2344]

I remember those wee sets, good times many moons ago

[@truthreigns7]

Wow this one brings back memories

[@graemedavidson499]

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

[@kevb1816]

There’s a CPT1473 on Marketplace at the moment (amongst some other nice sets) but I don’t need or have space for any more…

[@michaeldranfield7140]

Chuck some furniture away to make a space???

[@German_byte]

Great to see you using your analogue Sanwa meter. Have you had this meter for many years or is it a relatively recent acquisition?

[@leetucker9938]

clean tv is a happy tv

[@tubeDude48]

👍

[@ed731pdh]

Araldite is your best friend......

[@REVERSE_BIAS]

Where did you get your capacitor re-former from please Michael? I've got a sneaky feeling you're going to say you made it!!! 😊

[@ukfmcbradioservicingTango21]

Michael enhanced a magazine project & based his reformer on the design published in Everyday Electronics, July 1995. Richard, G0OJF, UK

[@REVERSE_BIAS]

@@ukfmcbradioservicingTango21 Thank you Richard! Much appreciated.

[@neilbirkett835]

Beautiful machine,wheres the name crowbar circuit come from,what's its purpose 😊

[@andysims4906]

I was thinking the same . I know it’s a well used term . But why the name

[@robinsutcliffe-video_art]

@@andysims4906 "It operates by putting a short circuit or low resistance path across the voltage output, like dropping a crowbar across the output terminals of the power supply"
