Nice repair, Mark the Cat Lady. LOL I have seen commodore 64s that came across my work bench where people had used too long of a screw. Ouch.

[@Chriva]

I'd check if that thick pad under the crystal is ground and solder the thing to the board. Free floating crystals is a big no-no because they usually end up exactly like the one you replaced. At least put a double-sided pad between it and the board :)

[@MarkFixesStuff]

Funny you should say that, because I have put a double sided sticky pad on the shopping list for when I finally get around to cleaning it up. Thanks for watching and taking the time to comment. It’s really helpful!

[@coyote_den]

The original crystal had a heat-shrink Atari label on it, so it wasn't soldered down. Probably why it cracked.

[@MarkFixesStuff]

Entirely possible.

[@TEBLify]

That's a nicee and easy fix, wish they all were like that. I got an 800XL that had the wrong colours, had to rebuild that section piece by piece until I found the culprit - a resistor that was reading as open. It wasn't burned or damaged in any way, so I assume the previous owner believed their games were supposed to look like a pink and purple mess 😅

[@MarkFixesStuff]

Reminds me of when I worked with @rmcretro on the CD32 FMV module, and some of the passives had died leaving ONLY the video with a pink tinge. That was fun to scope out!

You almost got off to a good start... and then at 50 seconds I have to take a break and breathe when I see you manhandling Phillips (or is it JISIS?) screws with a goddamn Pozidriv! 🙂 It's a good idea to glue or otherwise attach those crystals to the board, they don't like vibrations.

[@MarkFixesStuff]

Yeah. I know. I wondered who would be triggered first haha!!! I’m revisiting the machine to clean up the board and tidy the install when I upgrade the RAM so don’t worry. I’ll use a tri-wing next time to get you to comment and give me that precious engagement that KZbin loves. 😉

[@techkev140]

Really loved the shape of the later Atari machines, they did well to unify the range. My first experienced of it was with the 520STFM, loved that machine, apart from the under keyboard mouse and joystick ports (!...?). AMSTRAD rewired the ZX Spectrum 128K+2 joystick ports so no Atari type joystick would work (£££?). The plot didn't work, rewired joystick extension cables for a few £s solved it. Extender cables then went on to avoid wear and tear on the ST (& Amiga) ports. How do the joystick ports on these XE65 models usually look? Also screws, this 65XE had a fair few of them. Metal screws in plastic, eventually don't key if opened too many times. The ST and Amiga suffered these maladies.

[@marky26uk]

I'm sure that variable resistor on the pcb alters the colour frequency.

[@MarkFixesStuff]

I’ve not looked into it but I’ll have a butchers!

[@firstsurname9893]

@@MarkFixesStuff It's definitely for color (sic) delay adjustment. If you look carefully you'll notice that there's a hole in the bottom of the case (next to the label) that continues through the shielding and the PCB to the underside of the pot. It's supposed to be used in conjunction with the Production Test Cartridge which, unlike the self-test, includes a video calibration test. If you're interested, grab the ROM from AtariAge and run it from the Uno.

[@MarkFixesStuff]

@@firstsurname9893 super info! Thank you!

[@GeezerGamesRetro]

How did you know the crystal was at fault? Surely you had to do some troubleshooting beforehand.

[@MarkFixesStuff]

Hi Geezer. This was a nice easy fix because the troubleshooting process I followed actually started with the Xtal. In the past I've had issues with Spectrums that have had missing or drifting colour and it's been down to the crystal being duff. Because they are actually quite fragile I check them first as a matter of course. The 4.433618 Mhz Xtal is the part of the circuit that encodes the colour into the composite signal and I was in the process of trying to check the frequency when I had the burst of colour just by touching the leads of the component. That was pretty much an indicator that the crystal was not in a good way and I have a bag of them for the PAL machines I repair. If the Xtal was OK I would have moved backwards through the colour part of the schematic until I found what wasn't working, but sometimes it's a quick fix and a short video like this one.

Greetings, what model Weller desoldering station were you using? Sometimes solder wick is simply not enough.

[@oldguy9051]

The desoldering station isn't made by Weller but either a Zhongdi ZD-8915 or a clone of it. Basically, you buy the variant that looks similar or identical and has a 90 watt handpiece. I have a slightly older one (ZD-8925) which has a nice LED temperature readout instead of an LCD but the same handpiece.

[@ridiculous_gaming]

@@oldguy9051 thank you.

[@p_mouse8676]

You could basically just leave the board as is without removing. Removing the crystal is easy, than remove the old solder, next just cut the legs of the new one at the same length, bend them and just solder it in. The solder will go through the entire via. Saves a lot of time and hassle. I have been doing this technique for over a decade, works just fine.

[@MarkFixesStuff]

Do you mean solder the new crystal to the legs of the old crystal after cutting it off?

[@p_mouse8676]

@@MarkFixesStuff no. You add solder to the pads/vias of the old crystal. Pull the crystal in the meantime out. Remove the solder with a solder sucker or wig. Put in new crystal and solder the legs from that same side. The via will flow the solder all the way trough. This technique only doesn't work with single layer PCB's, since they don't use vias. The main reason why I prefer this method is not just only saving time. By not having to remove the whole PCB incl often many other things, there is less risk of breaking things. Especially when they are from plastic that can be brittle. I do the same with other components as well btw. (resistors, ceramics etc)

[@keanebgONE]

That’s seems silly, how do you see how long the legs stick down, you need to clip them so they don’t short on the grounded rf shield.

[@p_mouse8676]

@@keanebgONE you can guess pretty well how long the legs need to be. So there is absolutely no danger of shorting things.
