You can get better results by skipping the Dremel entirely. Drill a few holes in the center (I'd say about 3?) and do everything else by hand with the file. It will just take longer.
Funnily enough, this could theoretically help with some European CRTs as well. My Beovision Avant from 1996 has some image processing going on (It's widescreen but NOT a 100hz model) even though I feed it RGB through scart. The main problem is that it has a similar red push which is a bit annoying but it's definitely not as bad as with this Toshiba (it also has scan velocity modulation but that I was able to disable by removing a cable from the neckboard. Overall the picture is pretty amazing so I'm not too bothered with the processing). I'm sure there's a lot of European sets with similar image processing even though we are able to feed them RGB through scart. RGB modding a RGB capable CRT would probably be an overkill but I wouldn't be surprised if someone in this hobby is gonna look into it some day.
Man, I had that exact model of CRT before I lost it in a house fire just over a year ago. If I could get another TV like it then I would love to do a mod like this to it
For TVs with component input, it is better using those as the RGB inputs and set the blanking to the right voltage. Even the video circuit shows that component inputs will act as RGB input when set up correctly. For a TV that I have, I've used the component inputs, then set the TV to AV2, when blanking with the correct voltage, it accepts the RGB signal. Each set is different, so the service manual can be checked to make sure this can be done.
WOW! It really does Steve. That's amazing!! I never thought much about it until seeing this video. You really opened my eyes brother man. 8^) Anthony..
Component is also known as “Y Pb Pr”, which is a different colorspace than RGB. Y is “Luma”, which is basically black and white TV. Pb and Pr are used to calculate the color information, but not as simply as combining colors like RGB
Hawt dang! Talk about timing! I've just opened a 27AFX54 to recap and was wondering about converting it to RGB...unfortunately Sunthar is backorder on his mux kits 😟 I guess I'll have to download the gerber files and get it printed by PCBWay or something.
18:40 So these Toshiba sets, (not just the AFs) made by Orion from 2003-2005 use a Renesas jungle chip that has shifted chroma over component. That is the artifact you are seeing, with the reds and blues not lining up. (Also, reds are over-saturated too, aka red-push.) The Orion-shiba sets from 2006-2007 use a Sanyo jungle chip that looks even worse, and it can't be RGB modded at all.
In the future consider soldering sync to SVIDEO instead. I believe this bypasses the composite comb filter and as a result the picture will not shift to the left as much. It will still shifted, but a lot less. The downside to this is you may need to plug in a 'dummy' SVIDEO cable so that the TV goes into SVIDEO mode. A $2 unpopulated SVIDEO plug will achieve this. Also the 240p test suite has a left and right audio test which you should always check when performing these RGB mods. Some sets, specifically Sonys, require both audio RCA inputs to be populated or it will not activate stereo and so audio will be in mono. If you run into this scenario, then you will need to connect dummy RCA plugs into both L & R inputs which will forces the TV to activate stereo.
Incredible work Steve! That feeling when you turn the Super Famicom on and that sweet sweet signal displays in all its glory! Pat yourself on the back for this one!
I have a 86 or 88 s video 27" Panasonic Omniart. I'd like to try rgb modding it. Sunthar told me Panasonic have weird rgb, that it would probably be really dark. I found its jungle chip online. Thinking I might try ordering one to test with. I found its datasheet for a similar chip that looks like a never version or revision. To scared of breaking the tv. It's s video is super sharp. It's the first set I picked up after getting back into crt.
What’s not clear to me from this gentleman’s story is his vac status, which makes all the difference in the world when learning from another persons health experience since 2020. Very glad to hear it was a success story.
A Hot chassis doesn't have an isolation transformer in it that decouples the mains voltage from the TVs electronics. If you added RGB output to the TV and if someone plugged the TV into a incorrectly wired outlet (Hot and neutral reversed) or just plugged it in upsidedown the ground pins and the shielding on the connector can be energized with mains voltage.
My grandma has a DS31590 just sitting around I don't know what happened to it, maybe I can fix it Apparently it has to do with the picture, but what specifically is wrong I don't know
I’m literally in this same boat with my Sony/dell p991 monitor. Monitor was working flawlessly. Decided to recap it as it had a lot of usage. Got it recapped. It worked great… for a week… then the screen got garbled and eventually stopped working.. thought for sure I had a bad cap. Spent a week going thru.. assembling and disassembling numerous times.. trying to fix the screen issue.. then all of a sudden I lost power.. I’ve been all through it.. eventually found 5 so far of lifted traces.. repaired those and still nothing.. I’m assuming I got more.. Point is… I’ve been dead set (no pun intended) on trying to get this thing back up. It is extremely frustrating and a brutal process.. but I’m still holding on… lol. Thank you for this video.. it’s giving me encouragement now to proceed…
It never ceases to amaze me how retro and fragile stuff costing a fortune gets overcharged for postage to then go on and use the most cheap ass courier and the worst packaging/protection known to man. If it's only going to get returned because of damage what's the point. If you're taking that much money using a shit courier and shit packaging is no excuse.
Magnavox and Philips tv clone the silvnia tv,,i have one from early 90s and still working like charms,needs a factory calibrate i guess but the image its very good
That was a great video. I got a call from an elderly man who wants me to look at it. Lol. I wouldn't feel right charging him. Back then, I was a big soundblaster fan. I had the best sound system than anyone in NY State Thanks for the memories this video gave me.
I love that classic woodgrain look Steve. I always use to be interested on having them as a first choice for appearance to have in my living room for others to take notice. Anthony..
