Re: MS8-26 Horizontal Width Coil

It would be easier to buy an unthreaded ferrite rod of similar diameter and length.

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...

Re: nanao ms8 26SU d431

Depends on what's damaged. If it's the rubber it can't be salvaged and that kind of hook is held by a ferrule crimped on the cable. It's much better to replace the whole thing with one likle this which is very easy to install:

Re: ¥Nanao ms-2931 tube swap (can't get a good picture )¥

it's quite possible that the TV tube doesn't have the same deflection angle as the 2931 tube and the yoke which is shaped for a specific angle doesn't work on the other tube. Look for a number (100 or 110) embossed in the glass. The TV service manual would have helped but that model doesn't even sho...

Re: Nanao MS9-29 (05A00585D1) dead

It is unsure if it's shutting down because the anode voltage rises above normal level. You would need a HV probe to see that. I would expect the B+ to stay at 75V after HV shutdown. A less safe method would be to suck solder off pin 14 of the 7853 and see if it doesn't shut down. It wouldn't be a ba...

Re: Nanao MS9-29 (05A00585D1) dead

No sign of life from the flyback. Does your multimeter measure frequency (Hz)? If so check pin 13 of the 7853 for 15KHz pulse at startup.
