Datasheet websites do that a lot. If it's PDF.js, Firefox's PDF viewer (or a fork of it), I just right-click to "Show only this frame" and it goes fullscreen. It might have shenanigans such as disabled printing but you can press Ctrl+Shift+E and reload to check network activity for what address the PDF is loaded from and save that.
The worse ones are PDFs that exist only for SEO and contain nothing but keywords and a link to a paywall.
Finding datasheets and service manuals is a nightmare. So many websites claiming to have the right file, only to end up being a scam and not having any files. Having files they have no right to and are publicly available behind a pay wall. Having weird online viewers instead of just giving the file. Padding the file with extra pages of nonsense so they can claim more pages and a larger file size. Having the wrong file mislabeled. Etc. It goes on and on. And then there's the sites that redirect a thousand times and then crash the browser. I hope I didn't just get a virus or something.
All I want is to fix this old CRT from 1981 so I can enjoy it for a few more years, is that too much to ask? And back in those days they actually cared about repairability. Especially the services manuals with scope traces for the test points save so much time troubleshooting.
Archive.org is a good place luckily. If it isn't down because shit heads can't behave on the internet. As a species we really like to get in our own way all of the time.
And no I still haven't fixed up that CRT. It is working now after replacing two weirdly behaving transistors, a new power cord and a new power button (old one worked but didn't stay on unless you held it on). Replaced a few caps but most tested fine, good quality caps. Even the once I replaced were working, but marginal on the ESR. Cosmetics are also good, but there is still an intermittent fault with it losing horizontal size adjustment. It goes from fine and perfectly working to a little too narrow without any adjustment. 90% of the time it's fine, 10% of the time it's faulty and it switches random. I've been going mad tracing where the issue is, but I will fix it one day.
I assume datasheet websites just have pages for every combination of 3-12 alphanumerics to appear in search results, and then use shitty fuzzy string matching tactics to find "most relevant" items. It would help if they managed to extract package marking codes from datasheets so you can find SOT-23 parts by their 2-3 character codes, or whatever obscure system used by individual IC manufacturers. I think they have resources to make the experience way better but they prefer to turn high profits. Personally, I would not mind trying AI (not neccessarily a LLM) for the data extraction but I'd be cautious and only release it if it is decently reliable (but I know they wouldn't bother with that).
Pretty sad that a technical manual for the monitor was most likely created but just not digitized in a way you can find. Intermittent faults are very hard to diagnose. What I would try:
I assume you've cleaned the potentiometer, which is also easy to check with an ohmmeter (mind the polarity or desolder it to protect the rest of the circuit).
Poke the circuit board with a non-conductive object to find loose solder joints or components with bad contacts inside. If the fault is not mechanical, it might be an overheating component.
Try adding a fan temporarily to see if the fault appears later, or use a thermal camera to find semiconductors that might go near their threshold temperature (150 °C for the silicon die).
Find points in the horizontal deflection circuit where voltage or waveform changes as the fault manifests.
Oh boy, I sure am excited to websites hosting PDFs! I love when the tool that everyone uses for hosting and viewing HTML get to be blessed with the perfect format that is PDF!

It's amazing and such a good user experience!
I love that PDFs are so difficult to transform into HTML, too. I would never want the besmirch the publishers oerfect one approved layout by resizing the window!
I've always called Word documents and PDFs "dead-end formats" (DEF). Once you export your data to them, there's no reliable way to retrieve your data from them for further transformation like you can for YAML, JSON, XML, HTML, Markdown, &c.

FYI, if that's relevant to your field, every new article published on arxiv.org now has a HTML render as well.
And on many older publications, transforming "arxiv.org" into "ar5iv.org" leads to an HTML rendering that is a best-effort experiments they ran for a while.
That's really cool! What I really would like is a tool that converts PDFs to semantic HTML files. I took a peek there and it seems easier for them because they have the original LeX source.
I think for arbitrary PDFs files the information just isn't there. I've looked into it a bit and it's sort of all over. A tool called pdf2htmlex is pretty good but it makes the HTML look exactly like the PDF.
Works for some places at least. Super infuriating though. Why use the fast native PDF viewer in the browser when you could use a bloated and buggy JS app?
Fair, but certain corporate-mandated client-side PDF viewers are... bloatier. Though, I do like not having another window to manage when I open in browser, particularly when doing web searches. It pairs well with tab grouping extensions, and I generally don't use markup, so no loss for me there.
Every four weeks forever, or until you try to cancel and realize we've set the cancellation page up to just throw errors every time you get close to actually cancelling.
well they have to justify the exorbitant amount of money they charge for publicly funded science articles (apart from the obvious reason of thinking about the shareholders)
