i have an old and borked hitachi 27 inch crt that i yoinked from bunnings e-waste here in SA, watching your videos is helping me learn so i can hopefully fix that beast and enjoy it to its fullest
I enjoyed and impressed that modern technology can record and relay the high pitched whine. In high school very few people could hear that sound. I added it to the list of signs that I was destined to work with computers back when they were an oddity to most people.
Thanks for this - I know what I'll be doing tomorrow :) Up till now I've put an external sync converter inline when using RGB SCART devices that didn't produce csync. It will be nice not to have that rats nest of extra wires anymore!
Doing well bud! 48 here, but I got near constant tinnitus at a high pitch that's pretty similar to high voltage whine. That Spectroid app that Adrian Black often shows off is marvellous!
One of my 1084's has a DB9 video input (as opposed to DIN), and no space for a SCART connector, the other does have the space there for it. This looks like a really useful mod, I think I'll give it a go on the one that has the space for it, and that might become my preferred display.
I've got a Philips branded monitor with the same chassis, composite only. I'd imagine modding it for RGB, and scart, would be a bit more difficult. Tho, it does have loads of unpopulated spots on the PCB. And, rather annoyingly, I've seen an old forum post, where a dude off-handedly said he'd done a an RGB Scart mod on his... But didn't elaborate. Nor can I find any other mention of said mod. :D Interesting video, this.
I'm not the only one that was hearing the extreme high pitch squeal when you had it running am I? Like I know the standard CRT buzz/hum but this was way higher. I wonder if the frequency was off or something.
Thanks for the video! Is it correct to say that the changes to the last SCART mod and this one are jumper R405 and put a jumper in 9289 instead of the 2.2k resistor?
The charge is stored between the inner and outer conductive coatings of the CRT. It doesn't matter if the ground connection to the board is removed, all you need is to provide a path for current to flow from one layer to the other.
@@TheRetroChannel Fair play and thank you for the tip! I love your content and these sort of mods especially. but I'm always nervous about wiggly amps!
Quick question as i have the same 1080s as you with no scart. If i buy the scart rgb adapter to 1084 monitor din . Will i be able to use my OG Xbox on it. using og xbox composite scart cable ? And that will be ok for me . But what if i also try the HD OG XBOX scart cable on a modded OG xbox will it give me 720p ?
I don't think the adaptor will work as the Xbox doesn't output csync afaik. You may be able to use an Xbox scart cable that includes a sync stripper plus the scart to din adaptor. And no there's no chance of using 720p, the 1084 can only handle 15kHz (480i/240p)

1x 47K 1/4W resistor
1x 2.2uF 16V or higher electrolytic capacitor
1x scart connector - www.aliexpress.com/item/1005004046566803.html
Sync mod:
1. Move the transistor at TS406 to TS405
2. Remove the resistor at R405
3. Install the 47K resistor at R402
4. Install the 39K resistor at R403
5. Install the 2.2uF capacitor at C401
6. Install jumper links at 9281, 9247, and R405
Scart mod:
1. Install a jumper link at 9289
2. Remove the right channel audio wires (if installed) and reconnect them out of the way of the scart socket - see 12:14
3. Install scart socket
Ok ill open my NTSC 1084 and attempt the sync mod. That will be super helpful!!
Yeah give it a try. It should be the same for the NTSC version
Will that become a video, Adrian? I’d definitely watch it
I was going to say be careful with high voltage - then I saw it was Adrian lol. 😁
A video with a commodore part AND a cat - perfect. So finally it's possible to watch a retro computer video AND a cat video at the same time 🙂

Confirmed that the mod works great on a North American NTSC 1084S!
Great video. I could hear the high pitched whine at the end. I'll be 50 in April.

Fantastic vid m8! Will now try to mod my 1084s pal! Youre the best!
I have 2 1084 monitors for my Atari and amigas. A great classic
Very cool modifications!! Thanks for sharing
Everyone's on the 1702s and 1084s, great video, but please deep dive the 1902 🙏
The 1902 isn't so easily SCART modded, but it *is* easy to add analog RGB to!
There's no chance of me doing a video on the 1902 as they were only released in North America
@@TheRetroChannel 1901 is the PAL version
I've been watching your videos for years and only today did I realize I'm not subscribed to your channel... 😅
Amazing video mate !!! Thanks for this. If I could only find an affordable 1084..... I would follow your lead.

I have a scart to DB9 adaptor for my 1084S-P1, does the job and doesn't require any sync mod
Great work, Mark! Best in 2025 to you and yours.
Cool mod
Awesome work
Somewhat relieved I can still hear the 15khz despite being 41 😅
Me too at 40 😅

Oof yeah that might be a bit more of challenge. Can't help you there
I'm not the only one that was hearing the extreme high pitch squeal when you had it running am I? Like I know the standard CRT buzz/hum but this was way higher. I wonder if the frequency was off or something.
I just checked my 1081 (marked 1081 AU) has the same chassis & already has these options, got to work out how to add s-video.
Thanks for the video! Is it correct to say that the changes to the last SCART mod and this one are jumper R405 and put a jumper in 9289 instead of the 2.2k resistor?
Yeah that's it. And the jumper at 9281, which I didn't mention in the other video but it was mentioned in the comments
5:56 😃😍😼👍
🍪 It might be a bit burnt, it was cooking in Adelaide today.

The Commodore 1901 has a bunch of extra cutouts

not to be a worry bomb but was there no charge because you'd disconnected that earth already? ed: earth/ground same

Could you please disable automatic translation for your channel/videos? The auto translation is not helping ...
Thanks, I didn't even realise TH-cam had turned that option on for me by default. I've disabled it for future videos.
