Nanao MS9-29 vertical collapse?

[geekmiki]

Hi,

My MS9-29 decided to die yesterday...
When turning on it will take some seconds to show a very faint red line in the middle of the screen, that will gradually disappear.
Usually a vertical collapse would show a bright white line, so that's why I am a bit unsure.

The chassis was recapped about 10 years ago.

Any tips on where to start looking? Is it a vertical collapse which means looking at the vertical IC, caps and resistors in that area?
Anyway, any hint or tip is welcome.
Thanks

Yeh vertical ic

What game is in the cab ?
Or no game ?
As red is a bit weird

It's almost a bit embarrassing, it was just the cable to the remote that was partially disconnected.

I have a pfx with one bad colour gun I think ..
And it’s zero burn naturally ..

I will go back to it and try other stuff to see
Like I have a rejuvinator now that I didn’t have before ..

Then I could try tapping to dislodge a possible short of carbon diposits across the cathodes
