Anyone know anyone in the Herts/Essex area that can service CRT TVs? I have a Sony Trinitron 21inch that has a geometry issue that isn't solvable via the service menu and I don't have the experience/confidence to open it up.

Have you tried simply Googling this. For instance "TV repair shop in Essex" brings back Seaview Television, who have been in business for over 35 years, so they must have touched CRT sets back in the day.

The reason I mention this is that I use exactly this (well not Seaview because I don't live there) but I take all my stuff to a local TV repair shop. Now owned by 2nd generation but they love the old CRT stuff as it breaks up the monotony of switching out one knackered plasma circuit boards for another one. He even rings his dad up when I drop a cab off, and Alf comes out of retirement (he used to be an Arcade Tech guy bitd) to help out.

If you don't ask, you'll never know.

Yeah I've tried contacting a few local to me, (Ware, Hertfordshire) but most seem to repair newer TVs only. Just wondered if anyone could recommend someone specific.

I know how you feel, nothing near me would touch them, the place down the road had some old guy who used to service CRTs but he said no too.

So after finding nobody to help out, I just said fck it, let's get this screwdriver under the anode cap and see what happens! So glad I did, love messing about with them now. And boringly never got a shock or even a pop 😆

Started off with a 10 incher before tackling the big boys 😅

Hi, thanks for your reply. Perhaps these images would help clarify what I mean. It's drifted so much to the left that I can't move it back to center with the service menu.

There is a guy on Facebook called Ed Mullard, he has a shop that repairs CRTs - haven't used him myself but seems to have a good reputation.
I don't want to throw bad karma to anyone I haven't dealt with personally and know to be providing a poor service, but there was at least 1 guy on the Facebook pages that was mighty unimpressed with the service from Ed - so it might need more research to decide if he is good or not....

I was thinking about using Ed for one of my CRTs but after doing a quick Google and came across this thread on Reddit:
I don’t know how much of that is true, but it’s made me wary and I’m going to hold off for now.

Hi Hideous
Yes I can see the phase shift - you said the service menu is not bringing it back? - is the image moving when adjusting?? - if so I would put this somewhere half way and adjust your game console to overcome this - this normally happens when used in ntsc mode

It will only go further left so no amount of adjustments will sort it unfortunately. It's OK for tate games but playing normally it's quite frustrating.

I can't remember why it happens, but it's a known issue with lots of consumer tvs (RGB left shift). This also happened on them when new. The pro monitors usually have enough adjustment to overcome the issue, but the consumer sets had lower tolerances so you have to put up with it. You might be anble to compensate with some overscan? Just to say, Gerard at VIS has a good rep and is as good as anyone if you want a PVM serviced.

There's a guy not too far from us, Belfast area, that repairs old CRT TVs going back to the 1950s, as well a valve radios. We left a WG K7000 with him a while back and he came back to us and said he wouldn't touch it. Couldn't get a proper answer as to why not, except that they are more dangerous than regular T.V. tubes. Thought these would be easier to work on since no tuner or audio to worry about.

I'm fine with recapping and flyback replacements, but to further investigate issues is a wee bit beyond me, but still learning.

Not sure what they're getting at there when they say "more dangerous than regular TV tubes". They're literally no different - in fact as we know some TV sets have got crts in with identical part numbers to crts found in arcade monitors - and they're A designation crts same as in 99.99% of TV sets (I believe there's a tiny amount large crt TV's with M designation monitor quality crts in)! Also, all "modern" (late 70's,1980's onwards) chassis work on either isolation transformers or have built in switch mode psus, no more dangerous than a normal TV! And K7000's aren't hard to work on! I'd say arcade chassis are safer to work on those earlier TV's with valves and exposed wiring everywhere, as well as lopts with more "on show" - most lopts in those older TV's used to have to have a safety cage round them from what i've seen! :D
