MS9-29 Jail bar

[nonosto]

Hello friends

I found an astro city for my brother and it's very nice, especially a
perfect screen . The chassi has been capkited but there is a kind of
jail bar on the left. Its looks like a ghostly vertical bar. This seems
to be common to a lot of MS9. Does this get fixed? If yes, how ?

Thank you

do you still see the jail bar with rgb signal disconnected and brightness turned up so you obtain a raster?

also when you say cap kit do you mean every cap or just selected caps?

Long shot but when you PRESS and turn the horizontal pot on the remote board (i think its in the middle?) does it help?

I emphasise PRESS as I have a couple of slightly loose pots on my remote board and they don't function correctly unless you apply slight pressure to them.

I dont done it, but this jail bars appears for grey/black screen and disappear with black/black screen, it's visible with in white screen:

I will check but I am pretty sure all classic caps changed but the big red and the big green not.

ok its just the caps around the video amp ic, just change all of them.

c211,212,213 2.2uf 50v

c221 i think is 100uf 16v

check c101 and c107 to see if they have been recently replaced, the 47uf caps c201 etc look new
