r/crt

I bought a new crt, now i have two.

Imagine if this amount of effort was put into most CRTs. The wood, the control panel across the top, and the speakers on the side all give this set a very premium look. I grabbed this set on my journey to find my childhood CRT, a Fisher PC-340. If you ever see an 80s Fisher show up, grab it. They all look really nice. Unfortunately they don't show up often. In the past year I've only seen six within 1k miles of me.

This model is a 27 inch, which is larger than most other Fisher sets at the time which were 25 inches instead. This one has some issues. The speakers have some distortion to them and sometimes one of the two will stop working. The geometry is a bit wild as well. The scanlines are very thick towards the top of the tube and very narrow towards the bottom. This set has two composite inputs as well as composite out and speaker inputs.

These units were often sold as part of a home audio setup. Its really close to being a perfect CRT in my eyes. Previous models had a channel indicator as well as the glass pane in front of the tube. If this model had those features, this would be my favorite SD CRT.

I think that's everything. Wasn't this fun? I shared a set and didn't mention that CRTs are sometimes expensive. If you want to do the same, please make a post and share your sets. I would love to see them.

37 down, 63 to go. See you tomorrow.

I have tried messing around to get it working with a ruko but I am at a standstill.

Model: 20F424T

Sadly, there is no pincushion setting within the service menu. Is this considered very bad geometry or would you recommend just leaving it? Do I expand the horizontal lines to improve geometry or increase vertical lines? Any recommendations would be appreciated. Thanks y’all!

Whole ride home was hoping they weren’t selling me a dud

The horizontal geometry on my CRT is a bit screwed up. Any suggestions for fixing it?

Thankful that my parents don’t get rid of anything. This was in my bedroom growing up… now my daughter (and I) get to enjoy it!

It had been stored in a very dusty attic for nearly 30 years. What should I do before plugging it in and testing it?

I see this CRT in a local Pub in my City. That's the best picture I could take (ik it's horrible) But just by the looks of it, could it be Worth it to ask? (To me, looks like a monitor)

The university chemistry department in my city was apparently dumping a bunch of them. A guy working there managed to give out a few by advertising on fb marketplace and I was lucky enough to get one!

It’s almost the monitor (though not as high end as P70) from the famous ‘Wake up Neo…’ scene in the Matrix which makes it even more appealing to me.

Great pickup day! :)

Made my Windows 10 look like Windows 95! Even the startup sound is the OG.

Ive been using a hdmi converter with a roku for years and its not been great. Super excited to have a native SD setup finally! Got it on auction for $88. Any tricks to setting these up or straightforward?

So yeah I did it! I got this bad boy for free. It turns on fine but… we have issues. The front panel appears unresponsive, except for the buttons on the left (input change, under scan ecc…) but the ones on the right show no sign of doing anything. Also, the video indicator LEDs never turn on. The picture is way too bright and it’s ever so slightly shaking left to right, but the contrast and brightness buttons don’t do anything. Is it a problem with my inputs? I tried both SVIDEO and composite from my vga adapter… same thing. Any tips would be appreciated!

I've been working through modifying this set to accept a component and RGB signal. I had the component working fine but while troubleshooting the RGB input I must have done something inappropriate because now all I see is this.

Thus far I've removed all my modifications and have taken it back to stock as much as I can except for some of the resistors and capacitors that I've moved/removed. None of those moved/removed components had any impact on the picture prior to this. I had tested both composite and component prior to my little mistake and both still worked well.

I was using the instructions from the sunthar site: https://sector.sunthar.com/guides/crt-rgb-mod/sony-kv-27s42-rgb.html#step-5-connect-sync-and-s-video-detect

Problem is I'm not entirely sure what I did. I could've bridged two points with my soldering iron. I honestly can't say. I checked for solder bridges, loose connections, cold solder joints, everything. Normally I'd be seeing "input 1" right here. But now, nothing. just the blue zig-zags and a flashing status light.

Any advice where to start investigating?

Thanks!

I got this crt and when I turned it on the image was almost entirely green (see second image) so I used an Amazon degaussing wand (third image) to try to fix it, it got better but the corners are still green (1st image) and should be blue, i tried rotating it but that did nothing but make the screen look weird (not colors weird just scan lines weird) how do I fix this?

Spotted at a high school in my area. Exposed to rain and was told "it finally broke anyway" by staff
