My parents first colour TV was a Sony Trinitron.
Never gave any trouble.
The colour faded after a few years - all sliders turned to max.
Luckily a family camped in our garden for a week and the guy was a TV repair man.
He adjusted something internally that turned up the colour and got us a few more years service.
The best feature was not having colour but being able to watch the UKs third channel BBC2 which was broadcast on UHF. Old VHF sets being limited to 2 channels.

Well, the vent wasnt it. I jammed a piece of welding rod into all the holes underneath the rim; water care out better but that didnt do it either. I dug and scraped into that "siphon nozzle" hole at the bottom, also no change. Some of the YT vids said to use cleaning vinegar, which we happened to have on hand.
I drained the tank and vacuumed all the water out of the bowl. I could tell that the "siphon nozzle" thing had a clear shot up to the tank valve, as I could hear the air rushing when I held the vacuum nozzle over it and opened the valve by hand. So I poured in the cleaning vinegar directly into the valve port, let it stand for a few hours.
It initially filled the bottom of the bowl slightly. After some time, a large amount of water showed up in the bowl bottom - I have no idea where this came from - tank dry, water shut, no one used it. But it was almost full.
Now the dern thing flushes correctly, giving two gurgles at a single flush. Only trouble is, I_Have_No_Idea what a cup or two of cleaning vinegar actually did, nor where the additional water came from, assuming it was lodged somehow within the ceramic cavern somewhere, freed by the cleaning vinegar.
I'm just glad it works - wish I didnt have to go through the seal change to find out.

Hard water deposits build up over time.
In some cases, water becomes sluggish, even pools up in places unkown.
CLR cleaner once in a while does wonders, breaks down the calcium deposits.
I pour some down the overflow tube till it comes out the ring of vents in the bowl.
And let it sit a few hours, then a good flush.
Well, it's all good now. You're a master plumber!
That allows you to bend over and show your cheeks without apology! 🙂

Hi bucks bunny,
Yes, during that era, Yamaha did some mighty silly things at great cost to the consumer. There was generally no reason for a complication and it just looked like engineers showing off to each other. It comes as no surprise that these complications are typically what failed.
It takes a greatly experienced technician or engineer to figure out an over-complicated circuit, so service in the field became a nightmare. Especially since there is absolutely no reason for these complicated approaches to simple problems. It was just complicated for its own sake. What a waste!

I am not sure whether this is intended. For me Yamaha always looked like an army of very diligent engineers with mediocre knowledge. Too big to fail...
A Peavey 10 mixer with open slide pots.
The pots are unobtanium. Panasonic discontinued them 10 years ago. I found some mechanical matches on Ebay with a shorter shafts and different pinout. I took the original apart and used its shaft in the new plus applied some jumpers to get the pinout compatible.
It's a good thing I enjoy a challenge.
I've concluded there's no money in fixing any gear produced later than 1990 or so. I think I made $4.00 an hour fixing that mixer.

Hi bucks bunny,
I am agreeing with you, and added more comments.
Hi campsquire,
Yes. I mostly agree with you too. You have to know when to write something off as not worth repair. You can fix almost anything, but no point in losing your shirt while you attempt it.

I liked to read about using vinegar in plumbing jobs.
Indeed, it works like wonder.
Cheap, easy, it won't damage anything, very effective allowing time.
I use a lot of 8% vinegar, always keep ready a couple of 1liter bottles.
Dip stuff over 24 hours, and it comes back brand new.
Plumbers don't have time to work like that so they use much more aggressive acid ( HCl ) that can damage things or they change everything for new.
With time and 8% vinegar you do a much better work.

I repaired a "tea stool" brought from Thailand to the US by mom eons ago -- one of the arches had fallen out, probably owing to the forced air heating in the states -- unfortunately I fitted the fallen piece with Gorilla Glue. How can I say this politely -- looks like sp**ge on a blue stained dress.
Yeah, I need to get some more vinegar for that use.
CLR works great, a bit pricey, and you gotta use it fairly quickly on stuff.
Good for shower heads, coffee makers, etc for Calcium Lime and Rust buildup.

Neat trick with vinegar!
Not really a “repair” but with a cat in the house, I always keep a few bottles of regular hydrogen peroxide in the cabinet. Every now and then, the cat gets spiteful over something and pees on the rug. Dump one entire 98 cent, quart sized bottle of peroxide on the pee spot. Let it soak for 2-3minutes, it needs to get down into the carpet and the pad underneath. Soak it up with an old towel, and you’re all done. The peroxide breaks down the ammonia on contact. No left over smell, no stains, just a damp carpet.
Don’t bother with that Natures Miracle crap (or anything else sold in the pet shop) they are just very expensive masking formulas that don’t work.

Old travel alarm clock.
My sisters. Belonged originally to my granddad so sentimental.
Popped the case apart to replace the alarm set slider that had fallen out.
Pickled the battery contacts & surrounding area with vinegar to remove leaking duracell deposits. Smear of petroleum jelly over said contacts & job done.

No problems with color at all.
Everyone thinks peroxide is a bleach. I have not found this to be true. I suspect it has something to with people using peroxide in an effort to bleach their hair when I was a kid. My guess is that the concentration/strength of peroxide sold today is quite different (much more diluted) from what it was decades ago. But I’m guessing here…

One channel was distorted. Tube swap didn't help. Ok. Open it up. 3 happy tubes, one that doesn't bias up. Open cathode resistor! At least it didn't short 🙂 Back up and running and sounding great as usual. Now to figure out why that resistor blew in the first place... Hopefully it was just a tempermental tube 🙂 It's in the bin now.
