Weche Ok Baby identifying monitor and chassis

[ZeroGoukiX]

Hi guys earlier this year I acquired an Ok Baby from a friend and refurbished it. I’m pretty happy with the results except for the monitor. The monitor works decently enough but it’s having issues with colors washing out and I can’t get good black without the image being dim so I was looking into what I could do to work on it or eventually replace the chassis. My issue is that I have no way to identify the tube nor the chassis. All I know is that it’s a 28” monitor from Ying Tchin. I’ve searched around and can’t find any info on these. Has anyone worked on these before? Is the tube actually from YTE or is it just rebranded from someone else? The manual mentions that the 28” is from Pentranic but I don’t think this monitor is. Any help would be appreciated. Last pic is where it’s currently sitting at my local pinball arcade for the winter. Thanks guys.

I got my OkBaby cab from Yubiparts out of Yonkers a couple of years ago. I restored one of them. It has a Toshiba tube and generic chassis similar to (but not the same as!) the Universal chassis you see on Aliexpress.

It had caps that were outright detached from the board. The universal chassis was relatively inexpensive so I replaced the whole thing. Some photos: https://www.arcade-projects.com/threads/babys-first-candy-cab-ok-baby-restoration.32349/post-477398

I have a photo of the tube's model no. on another device... but it's a Toshiba tube.

It's possible that both my set and your set are non-original. But sharing my info for the sake of publishing info.

I appreciate it, it’s weird because both the tube and the chassis are from YTE. Most of the universal chassis I’m seeing both old and new don’t resemble what I’ve seen from this. Though I’m sure I can find one that’s similar enough to where I can go off of it. I’ve seen the Wei-Ya 828HR 428H and I want to say that’s the closest resemblance I’ve seen so far.

If you can get photos of the top and bottom of the PCB it would be useful; we can then compare with other known models to determine if it's possibly a clone.

YTE (Ying Tchin) tends to make clones of existing hardware, so it's likely that it could be a clone of a Wei-Ya (aka Aygo, originally).

It’s going to be quite awhile before I can do that because the cab isn’t in my possession right now but I’ll try to post those when I can.

So I had some time to measure the tube and take what pics I could, the tube is actually 27” viewable and 28.5”. I measured it before but I didn’t know that US went by viewable screen size so it is actually a 27” lol The tube does not have a tube code label on the monitor, there was something but its buried underneath and hidden. My apologies this was the best I could do for photos I cannot remove the monitor at this point in time. Looks like their own branded chassis after all. It does remind me of some of the Wei-Ya chassis I’ve seen.
