Default New CRT TV board.

This CRT board manufactured April ? 2023, bought for $47 You supply the CRT, coils and case. Why bother making such in 2023?

My favourite text message "I'll be there in five minutes, if not read again"

That's truly bizarre!
The results are pretty good though, considering it's only a domestic TV chassis, & multi-standard as well.
I believe that Chunghwa were one of the last CRT manufacturers. It's a pity they are not still around... we might have been able to get some CRTs re-gunned.
I wonder what happened to their manufacturing equipment.

For gamers that complain about lag with modern flat panel screens?

Also watching Shango066 last week, the movie prop industry has limited use for working CRT TVs, often with modern guts fitted, but it would need to work at 24FPS used by movie cameras.

I was quite intruiged by Adrian's use of the chinese board. Impressed by the width jumper and extensive setup geometry menu, but puzzled by the seeming lack of any frame height control.

For me who lived through the crt-swapping days of the 80's, used to greyscale adjustments and numerous other alignment even when fitting an identical-spec crt to a good chassis, the new pcb seemed quite at home in some random 14in tv..although the tube socket had to be swapped. Must be some magic going on in that new jungle chip!

I remember seeing these for sale on AliExpress around a decade ago. Back then, variations of the chassis were also available with SCART and/ or Component Video; Teletext as another option. Not sure about NICAM or A2 Stereo support, but it wouldn't surprise me!

They're primarily aimed at developing nations where it may be harder to affect repair due to logistical issues (lack of spares availability, etc). A 'drop-in' replacement chassis thus giving life to an otherwise written-off set with a decent tube; cutting down drastically on e-waste.
