After 19 years my Sony tv has developed a problem. It’s the first problem it’s ever had. When turning it on it can take several minutes for it to start after pushing the power button. Once it’s on it works as it should. I searched online but couldn’t find someone with the same issue but I’m not as good with the internet as most probably are. I know it’s very outdated but it does what I want it to do. Liking most things vintage I’d like to repair it if someone has experience with this. I bought the tv 12-3-2003.

 Well, offhand, I'd stab a guess that there's a problem with the TV's power supply. It sort of sounds like a capacitor issue there. And if a capacitor needs to be replaced, then it should be done cautiously because they can store a charge. Bear in mind that I've never replaced a TV power supply, and I generally just buy a new TV set as needed. If you have a Costco in your area then they seem to have the best prices. | ||

A complex set
It is not possible to know true cause from the information provided. This is a complex TV.
Some Sony TVs of these variety have self-checks that do not permit the picture to appear unless all checks out ok. One such function is the automatic picture-tube balance check. This check is done to balance the picture tube guns prior to the picture appearing. If the picture tube is aging, it may take longer and longer for the image to appear. That does not mean that the picture tube is bad. What I am going to tell you is to find an old-timer who fixed Sonys to look at it. There is a lot going on in the background with this set. Sony sets are not modular, you cannot just replace the power-supply as an assembly. And I don’t suggest throwing capacitors at the set as MANY will suggest. The result is probably futile. So no fix from me. Throwing parts at the set may work for a five-tube table radio or a 1964 Zenith B&W but that is not the case here. | ||

I had a look at the repair manual over coffee this morning and I think Paulg has nailed this one. | ||

1952 SCTV The Antique Radios forum has a section for vintage television sets. That's where I found a local guy to bring my 1950 Admiral back to life, and it was a fairly simple job of replacing capacitors. He didn't change a single tube, and the picture tube was fine. I had the Admiral revived as a 50th birthday present to myself, and it cost me about $100 for parts and labor. Considering that I only paid $5 for it in the early '80s, that was reasonable.
Here's a link to the ARF. There may be someone near you who can make repairs to your parents' TV if it doesn't have anything major wrong with it. There used to be a directory of TV repair guys, but I didn't see it when I checked just now. Poke around and you may find it.
