We have a 35" Sony CRT that just made a sound that would make me think of what a picture tube would if it were to burst. Definitely louder than a turn on/off sound. But there's nothing at all. No power light, sound, nada. Swapped outlets with the cable box, nope.
Is there a fuse inside most CRT's? Usually easy to access? This old (12 years?) beast weighs as much as I do (well, about what I would if I lost 5-10# :)), so I'd prefer to swap a fuse at home myself if there's such a thing. Ideas? Power supply? Not sure how far I want to go on a 12 year old TV! Amazing that I paid ~$1600 for this, and now one can buy a nice slim, better picture for much less, not that I want to, it's just our bedroom TV, but if forced....
That said I also have 2 @ 27" TV's, one was my main TV (as was this 35" a few years back) about 20 years ago. Still running strong every day in our sunroom (Hitachi)! The RCA is around 12-15 years old in another room, still OK, not used as often though. Amazing durability these things. Until now I guess. :)

There's good advice here on repairing it, but.... you can probably replace it for well under $100 by trolling Craigslist, local eBay listings, kijiji, thrift stores etc. With a bit of luck or patience (or a bit more money), maybe a larger and/or widescreen HD capable set. Even just progressive scan is a very worthwhile upgrade for watching DVD content.

I came across a Consumer Reports magazine issue from about 4 years ago, back when CRT displays were still in showrooms. Sony CRT sets got the highest ratings for picture quality, and only plasmas came anywhere close in the hang-on-the-wall displays.
Maybe the lesser brands just need more care taken with calibration. CU could have figured it wasn't fair to expect average consumers to have sets ISF calibrated, and simply used whatever presets the manual suggested.
I think perhaps the TV had some sentimental value (which is VERY weird for me, no sentimentality for objects here usually). It was absolutely my first purchase after my divorce 12-13 years ago. I lost my wife and thus my house and ended up in a condo. That big (at the time) TV (and new VCR and DVD player, $ at the time) made me feel just a tiny bit better about my situation.
Thanks for all the replies, bought a 50" plasma which we're putting in the family room for daily viewing and moved out the old 27" Hitachi into the bedroom. It's a fair bit smaller, but liveable. It's about 26 years old, so I'm sure also on it's way out as well!
Grant, you'll love the plasma if you have hd programming. If you only have sd, you will not like it as much as your old crt. That has always been my experience.

Because the 50" Samsung ended up replacing the 26 year old 27" Hitachi (and it moving to our BR), we're thrilled. Much larger picture and looks just fine on SD. Some channels are much better than others, but overall we're very happy.
Haven't tried a DVD yet, but will some time soon. We don't use that room for movie viewing, so the picture is not really that important TBH. I actually went with the intention of finding an "old tech" TV (720P ...?), but there were none anymore, and this was a pretty good deal so bought it.
The B+ is BIG big big. So if you get all touchy feely with the innards.. it may kick you hard... very hard.
Just curious.
I think just offering a reminder to be careful is VERY different that the fiat YOU MUST NOT DO XXXX. It's up to each person what the ydo. i can suggest being careful, I am not warning anyone they must not do what they plan. If THEY want to fiddle with 50,000 volts, not my problem.. though i would mention it is there, AND if I knew more, I would tell them how to do it too.
> a sound that would make me think of what a picture tube would if it were to burst.Actually CRTs do not "burst". Since they have a vacuum, CRTs implode (i.e. that is inward, not outward).
Fuses no not make much, if any noise, when they go. A load "pop" could be from an electrolytic capacitor exploding. Was there any odor after the pop?
From your questions, you might not be comfortable opening up the back of the set.

Power supply related and/or capacitor.
Good point on the fuse itself. Thought perhaps that the fuse blowing might have caused other parts of the TV to react hence the noise? I didn't smell anything, but it sits in an alcove built into the wall, so any odor would have likely stayed in that area for the most part.
I'm fine opening the set and checking for a burnt out part. If it's a cap I'll pull and replace. I can't imagine spending any money at a repair shop however on this age of a set.
It makes me wonder why after "only" 12 years it blew in the first place. Something else downstream causing the problem? Whatever it is directly affected the power making me think it might be a simpler fix.
Now, gotta get somebody to help me pull a 185# TV to the floor. :)
> Thought perhaps that the fuse blowing might have caused other parts of the TV to react
No, it's the other way around. Component failures may cause the fuse to blow (and maybe other components before the fuse can react).
> it sits in an alcove built into the wall
That's good for heat buildup, and aging of the TV's components. That could contribute to its "early" failure.
> Whatever it is directly affected the power making me think it might be a simpler fix.
One of the few things you wrote that I can agree with.
You might be able to find the service manual online. Even if you can't read the schematics, there are descriptions on how to open up the TV. The power supply board is mounted on a tray that can be unlatched and pulled out for servicing.
> Now, gotta get somebody to help me pull a 185# TV to the floor
I've found it to be a lot more comfortable to leave the TV on the stand. Soldering boards at floor level is not as easy as having it on the stand. (Or is the alcove just a small opening above the floor for a TV rather than floor-level for a RPTV?
What is the model number of your TV?
Regards
Good point on the alcove, one I discussed with my wife in the winter when I noticed one particular area of snow would melt first. :) I have a 70's house with the semi-typical split level entry. When I bought the house it was only used for growing drugs, closed from both sides. So I popped the wall open and voila.
Clean up the seeds (the mini-grow was accessed from the top of the front hall closet), have proper electrical (not just a cord for weed lights) and cable run in and I have a TV spot. It has lots of space around the TV for ventilation, but perhaps I was still asking for trouble. Excuse the old picture...
Model number... something S35...? I'll try and find it.

My last CRT was a 40" Mitsubishi. When I bought it I could pick it up and move it. As I got older I found that I could not. That's when I bought my first flat panel set. I gave the set to my daughter and son-in-law with the understanding they were responsible for moving it. The set is still going strong.

I remember probably exactly that 40" Mits, very nice TV. I think it was what I really wanted at the time but too much ca$h. All my TV's have been good, until last night. :(
