What's new

FS Egret 2/Windy 2/NNC/Q25 (Repair refund)

For Sale
The chassis is definitely not receiving any power? Fuse in the PSU?
Dont think its fuse as I get audio and my jvs to jamma is working I can hear growl working. Is there a fuse just for monitor power?

I'm going to try hooking up my weiya chassis and plug into the ac plug on psu tomorrow.

The only thing else I can do is take apart psu see if sharp hooked everything up correctly. It could be chassis
It's not a tosh tube
Is a sanwa pm1975 15hz 24hz

It would be a good idea to get a multimeter and check the power before you do anything else.

There is a fuse on the chassis itself and I think there are three fuses in the PSU, one on each board.

ok I connected weiya chassis worked for 5 minutes then it stopped we working. Monitor is fine. I think psu died.

Would anyone with any technical knowledge look at my psu and repair it. It's way above my head.

Alright, I can finally write about my whole experience.

After this guy Grant from the UK would not share the identity of the replacement flyback for the Toshiba chassis, I had to dig some more and come to the conclusion that this chassis shares the same flyback with the Nanao MS2931 tri-sync monitor.



Clues were :
- People have been buying the MS2931 as a replacement drop-in chassis because it is the exact same tube.
- Looking at pictures of the MS2931 and the Toshiba PB7534, the flybacks look absolutely identical.
- Finally, one of the 3 chassis I have on hand for repair has a flyback with the markings MSU1FUS11 on it, the others having reference from a Toshiba parts catalogue I'd have to guess.

CONCLUSION : Same exact flyback. Works great, 15kHz, 31kHz.



You can get the flyback from taobao through a proxy, or from donberg electronics in Ireland :

What had to be done also, a complete recap for one, I had some blown film capacitors too, and a few parts from our friends over at utsource :

HOT 2SC4288 : https://www.utsource.net/itm/p/1238239.html
Damper diode FMQ-3GU : https://www.utsource.net/itm/p/1710145.html
Bipolar diode D716 : https://www.utsource.net/itm/p/4370189.html
Vertical deflector LA7837 : https://www.utsource.net/itm/p/1016522.html

I just swapped a few parts and not an engineer / expert technician.... and they work great now.

Already made the order with UTSource. They are awesome to deal with btw. Working with a Chinese buddy on the Taobao parts now. Going to grab spares. I believe the FB is the same for the Toshiba Pure Flats as well, if I am not mistaken? I will find out this weekend. If not, I suppose I will have a few spares to share.

Thanks for the 411 @SnakeGrunger.
 
Alright, flybacks from Taobao will be here on the Sept 16th (EDIT: I had my friend buy 10 of them). UTSource parts should be here by then too. Will keep you guys posted.
