Re: Single dot on screen after chassis/tube transplant

That's one of the two decoupling caps on the 200v supply voltage for the RGB amp transistors. Not related to the missing deflection.

Re: Single dot on screen after chassis/tube transplant

Yoke connector visible in the last pic (red/blue/yellow/green wires). Whether it is plugged all the way in or not remains to be seen. The header could have broken solder joints due to wiggling. Try the other header.

Re: Nanao MS8-29MSG - Broken CRT Socket pins, can a similar Aftermarket part be used?

My big question is... Are the original SMK sockets swappable with any other similar spares? Is there an specific pin configuration for the Nanao ones? A difference can be the spark gap, i.e. a metal strip built in the socket that goes very close to all the pins and in case of a high voltage flashov...

Re: MS8-26 Horizontal Width Coil

I used the core of a width coil of an Italian TV (same thread as that of a Hantarex monitor). They're slightly thinner so I put a few turns of tape around it until it was tight enough to be pushed/pulled instead of screwed which is more convenient anyway. Immagine3.jpg Immagine4.jpg Immagine5.jpg

Does pincushion adjustment work? Horizontal size limit (VR452)?

Re: New Wei-Ya / Makvision Tri-sync M3129DS-LG 1 Sec Click of Death...

That's the AC filter. I don't think it's bad, maybe a shorted diode bridge could get it hot but in that case the power supply wouldn't work at all.

That's probably the PTC. It's normal that it gets very hot.

Re: Nanao MS9-29 (05A00675C2) dead

Sounds like a problem in the power supply. Check the B+ diodes on the output (D951, D952, D956), the caps (C951, C952, C953). If they're OK check the primary side.

I took it to the technician, and he repaired the monitor, but when I took it back it still had the same issue. I took the chasis and tube this time and he said it was the yoke.
If it was the yoke what did he repair the first time around? :think:

I still say 48cm tube is common as muck.
Too bad candy cabs don't use that size (if we don't consider that monstrosity you posted yesterday).

Re: TV - Hitachi C2156TN, tube in this any good?

19" (18" viewable) as it should be intended in Europe and Japan is indeed super rare but a lot of people call 19" what is in fact 20" (19" viewable).

Re: TV - Hitachi C2156TN, tube in this any good?

Tube size is wrong. There's no arcade cab that uses a 21" / 51cm tube. How did you know it was a 21 inch tube, he said it was 22, is there a website with a database of tv and the tubes inside? Being the owner doesn't make you an expert. It's a 21" (20" viewable screen) because the model number is C...
