Super Mario Bros!

Picked up my Super Mario Bros, finally, from my friend's place.....this is one I got from Roundscreen years ago, but never picked up from his house, with my untimely double move and divorce.....

So, here she is! Need to get the screen fixed, as it compresses at the top. Any ideas as to where to start, guys? Already tried the vertrical size, and it just rolls up more, top and bottom.

NICE!

There are probably a few bad capacitors in the vertical output section - if not a driver/output transistor as well. Also look for open or increased resistor values in the vertical output circuit. Any one of these can cause the foldover you see.

all that use and abuse after yeArs of use kill caps in those video monitors. I worked on a few of those in the past for an arcade center up here and slot of them were always leaky elecrolytics and resistors. Good luck that looks like a sweet and clean arcade!!

Stupid question, but can't I just adapt a regular TV chassis somehow, or is this something special?

Tim
The crt still looks good so I would re cap the monitor. It is a RGB monitor so a tv chassis would not work. Google amusements plus in Rochester and give them the make and model number of that monitor. They might have a cap kit for it. I can show ya how to re cap the monitor, It is not that hard and will last for years when done. The cabinet did clean up nice, Trust me, It did not look that good when Tim got it

Probably 4 or 5 electrolytics tops, since it does look good as everyone's mentioned. Is it a Sanyo monitor by any chance? I remember seeing a Donkey Kong with one of those and it too had vertical troubles.

I don't recall what monitor Tim's game had. It was taken out of service long before I worked there. {They might have changed it with a newer one.}
I have a Sanyo monitor in my donkey kong and the picture is vary clear and bright with no burns. The best thing to do with the old monitors is re cap the whole chassis or it will fail again.

That's true, Ed. Capacitors can't be expected to last longer than 20-25 years !! After all they were never meant to last that long really....

After an hour or so of play, the monitor's color is starting to fade.....kind of looks like a sunfaded photograph now. I'll take some more pics and find out what kind of monitor's inside.

I took a look in the warehouse today and we still have some of the old monitors.
We might have one like yours and the boss will sell it to me cheap.
Also the fade could be the computer power supply. So we will need to see if your game has the old power supply. Some times you can convert older games to a newer power supply.

Look at the manufacturer data. Needless to say, there are always exceptions . 46 years and counting on one of my Admiral sets.
