    Posted: 08 Jun 2019 at 11:46pm
I bought a NOS New Net City from g60hot a few months ago. Essentially never used.

Never got around to trying it properly until today. Played for 1 hour and was working grand with my cps2 setup.

At which point the screen flickered crazy horizontal making a weird noise (I thought it was the game). The screen then shrunk to the middle vertical 3rd of the screen.

At which point I turned it off thinking just a fault.

Turned back on, and got an intermittent single red line down the middle, which turned into a bright white line down the middle.

At which point I turned off again and smelled BURNING. (won't turn it on again).

Does anyone have an idea what happened?

I haven't a clue how to start even safely getting my monitor out for repair. Is there anyone on here who can fix?

Absolutely gutted really.. I was so happy playing it.. The quality of the image of the Toshiba tri sync was insanely good. I only knew her for an hour :-(

Thanks in advance
Adam

I am by no means an expert but that sounds like horizontal collapse. Could be a number of things but should be fixable.

Strange as it's hardly used.. maybe a dry joint but the burning smell indicates a component is not happy.

Hopefully one of the monitor gurus will know more, but it'll probably mean you'll have to remove the chassis and send off for repair.

..or take your chances on a replacement chassis from Yaton..

Yanton has some tosh chassis in stock that should be compatible if you get stuck with the repair: link

Just to be clear:
 
Vertical line = bad flyback
Horizontal line = bad vertical amp ic usually caused by bad capacitors.
 
I really couldn't read if it was vertical or horizontal, but gunblade knows his stuff.

Thanks, yeah it was a vertical line down the middle. Must be fly back.

Ive ordered the chassis you linked to Chunkskin, will get that serviced before replacing. I presume this is a tri-sync chassis?

In time will get my busted chassis sorted too.

For a total noob like me, it all sounds scary removing the chassis (not damaging the tube / or even dying ha).. But I suppose I must learn by doing.

Yes, it's a tri-sync chassis.  I got a replacement chassis for my Tosh PF from Yaton and it works fine - just needed a bit of tweaking to get a really nice picture.

There's a few slight variations on these chassis, but they are all compatible.  Some have more pots on the actual chassis to adjust the picture, but most I've seen are this type with everything done on the remote board.

There are hidden menus on these too - you can get a modded remote board to access the extra menus if you find you need it.

If you need a hand swapping the chassis over let me know, I can pop over and help, I can also sort any convergence issues if you get any

Thanks Rich, that would be amazing. Im not sure I would know where to start haha. 


Might be a couple of months before my chassis arrives from china and gunblade can service it too, but I'll let you know.

Im slowly learning with all this ;-)

Last time I bought something from Yaton it turned up in around a week (in fact I think it might've been under a week), so you should see it a lot sooner than a couple of months!

He's going to get me some photos apparently.

Be interesting to know if the flyback you get on the replacement chassis is the same as the knackered one on your existing chassis..

As the chassis you've got is so new it might be better to just swap over the flyback?

I have a dodgy chassis that gave a few intermittent faults that might be worth sorting as it's newer than the ones Yaton has for sale.
