Monitor issue *Video link* - Electrohome G07-907

[acvieluf]

I know the sticky said get the monitor model first, but they're a friend's machines, and i'm waiting to get the info from him.  (19" from a Bump 'n' Jump machine, using the Deco cassette system.)

Here's the issue (with me): I'm a complete newb, and yet would still like to repair (or give it to someone to repair), rather than replace. 

Here's the issue (with the monitor): after about 10 minutes of warm-up time, the tube glowed, and the screen came on.  But the glow would go out and come back on, and with it, the screen itself.  You can hear the monitor humming off and on in the video, as well as the screen effect. 

One last thing: While running a small shop-vac on the same wall outlet, the tube and screen would stay on completely!  It was funny, and kind of baffling.  Is there too much current getting to the tube under normal circumstances, causing the cutting out? And the shop-vac saps some of it, helping it to stay on? 

Any advice welcome. Thank you.



EDIT - my own photo of monitor also added, still waiting on a photo of identifying marker.

if you cab is affected by operation of other items using the same power socket then the issue is bad wiring somewhere on the power line- maybe something as simple as a loose connection in the mains plug

You can hear that something is arcing somewhere. I couldn't see the neck glow coming and going in the picture.  But if that's the source of the noise check your neck board for cold solder joints.  It could also be arcing inside the neck socket.  There's usually a spark gap in the neck socket and if that's corroded that could cause that. Otherwise find the source of the noise if you can.  Also looks like you have a game board issue too.

I'll look into this, thank you!

You can't see the glow coming and going through the camera, but it was obvious to the naked eye.  Thank you for the input, i will check these things when I get over there, next.

Yes, I just assume that's a problem with the cassette itself.  Or should the PCBs at least bring up the DECO boot screen?
