Naomi Sanwa Monitor Fault

[ninjawyatt]

I've got a complete 29e31s monitor but the tube has ID burn. I can remove the chassis and you can have it for £30 + post if you want.

I <3 this place

£150 for a new monitor,tell me where those are and i will snap them all up
I think you will find £150 for a new chassis only-about £400 for a new monitor if you can find one

I was quoting £150+ as a ballpark for a complete used monitor. When ninja said "new" I suspect he meant new to him

Franco is awesome

That is indeed what I meant.

Ok, so looks like Ive secured a new chassis thanks to Franco. Next question - Replacing a chassis on a Sanwa 29E31s. Is it just a case of unplugging/unbolting everything that holds it to the monitor and then fit the new one, or do I need to discharge the tube first? Ive been in the motor trade for 14 years, so Im comfortable unbolting, unplugging stuff, but Ive never discharged a monitor tube and have no idea of how to do it.

[Spectre]

You'll need to discharge the monitor to swap the chassis.



Beyond that it's a reasonably straightforward unplug the old one, put the new one on. Just be gentle with it, especially the neck board.

No need to discharge. This monitor self discharges at power off.

Still sensible to follow the above when removing the anode cap on any monitor.

[Rossyra]

I had a zap from the anode cap once. I enjoyed it.

[Spectre]

Tastes like razors.

[ninjawyatt]

To Fry or not to Fry... that is ze question. ZAP!

Anyway, so what are we saying, I do have to discharge it... I dont? Obviously if there is any chance there could still be charge in the tube I would rather discharge properly than discharge it down my arm! But bear this in mind - My cab would have been disconnected for a week, or just over a week when I will actually replace the chassis. I do have electrical knowledge and experience through working on cars and I would have presumed the monitor would not be holding any charge after that length of time, but I dont come across many monitor tubes when working under a bonnet so please put me straight if anybody has the intel

This.Dead easy to knock up a tool to do it with and,this wont be the last monitor you mess with

[Rossyra]

You'll be recapping chasses in no time. Once you zap you just can't stahp.

Ok, cool. Hopefully I wont me messing with anymore monitors soon, cause this is my only one and it blew after about 2 months of owning it!

I just finally watched that video..... Wow! If I knew it was that simple I would have just done it even if the monitor had been disconneted for a year!! Earth it out with a screwdriver. I really thought it was going to be more technical than that. Like using a multimeter?! Oh well, Im not complaining.

[ninjawyatt]

Complete monitor chassis and neck board arrived today from Franco. It was suprisingly easy and quick to change! My only concern was that I couldnt get a 'pop' when earthing out the anode cap. I tried over and over again to ensure I was doing it correctly, and in the end decided that it must have discharged already. I wont deny that I was still a little nervous when handling the anode cap ...... But Im still here

The good news is - my cab is alive again! The suprise news is - its a better picture than before
I could never seem to tune the Naomi start up screen to pure white, it was always a little green. I presumed it was something to do with the monitor screen, but its now minty fresh white!

Thanks to everyone for all the advice and help and an even bigger thanks to Franco and his super cheap sale.

[Hewitson]

Maybe the degauss circuit wasn't working on your old chassis and on this one it is.

[FrancoB]

Awesome mate, glad to hear it's got you up and running again
