Nintendo Space Firebird

[simplesi]

Hi!

How's it going? I've ben busy here... restoring a Nintendo Space Firebird Cocktail (pics of the restoration to follow). I have complete polished, painted, re-veneered, fixed a vertical collapse, recapped the monitor, had the pcb professionally repaired... nearly finished... NEARLY!

I have a couple issues that I would like to fix that would make this an absolute mint restoration.

The first issue I would like to try and fix is that I cannot centre the image on the screen and seem to have the image roll over on the left side of the sceen (see pics below). Does anyone know how to resolve this or had similar experience in this?

The second issue is that sometimes the board does not boot. I know when the game works that there is some sound on start up. Occasionally, there is nothing. I know power is getting to the monitor. COuld this be a loose coneection to the gameboard? The voltages seem correct. As this does not happen all the time could it be a PSU problem? Should I recap the PSU?

Any help to these problems would make my day. With your help this will soon be my first ever (sucessful) restoration.

Thanks in advance,

Si

Have you some experience in this Etienne? Desperate to find a solution.

is there not a pot somewhere that is called "v hold" or something ?

[simplesi]

The problem is that the image will not fully unroll.  On the left side of the image it curls around on itself. Playing with the pots do3s nothing. Could something else be causing this? I've recapped the monitor. Could the B+ affect this?

Curl over is almost always a cap. Either you forgot one or you put in a bad one.

Don't say that Andre. I just recapped a la Bob Roberts. Is there a good way to test the caps?

Some of us use this, it is a great one with discharge function
