ok my mario wide body i just bought has a problem with the screen rolling up and down (vert)

after digging into the game i have found i can get the monitor to steady but the picture is off center
(bottom of the screen is in the middle of the tube)

my monitor pot seems to be fine i have tested it and again like i said i can get the screen to steady but have the above mentioned problem with screen pos


the horz pos pot on the boardset does function but my vert pot is totaly unrespoonsive
after inspecting the board set i found this cap at location c3 on the vid board

the manual lists it as a 0.1 uf 50v film cap
i wne to the local elect supply and they said they did not know what a film cap was but they gave me this 100v mylar cap and said it would work

it has the numbers 104j on it but does not list the uf can someone confirm that this cap will work and that is the correct uf
and also do these caps matter on the poliarty and if so how do i tell wich leg is what

thanks guys

and the v hold pot at vr353 on the sanyo ez 20 monitor 8 - 200k
the elect supply store did not have these

as for the oreintation /poliarity on this replacement cap what leg is pos what leg is neg or does it matter on this
i also do not se the poliarty marked on the board set unlees the p with a circle around it above the right leg of the cap is telling me postive

and is there somplace other that bob to order the pots his site is a pia to go thrue and im unshure of exact pots i need (damn im a newb) i also would preffer to use my cc to order and bob does not accpt cc
 
That cap is non polarized which means it doesn't matter which way it goes in. As for Bob
this is what you need http://www.homearcade.org/BBBB/ninpots.jpg and he's a check or money order kinda guy. Email him with what you need, he'll email back the total and then you mail him off a MO or check. You'll have your parts within a couple of days.
 
whooooo hoooooo
thanks dokert and gregatron it seems it was that cap used my new desoldering iron removed the old cap installed the new one and bam my vert pos pot now works and im able to get a non rolling screen pots all seem to be nice and responsive
now i do have another problem there is a white streak going horz left to right(like the brightness is to high) but the brightness adjustment will not remove it is did not have this before i replaced that cap any ideas

not like that it was like the brightness was to high or the color pots were not adjusted right but it went away and has not come back
im betting that it was the fact that my new cap had not charged itself fully (after it went away i powerd the game down and left it off for 10 mins and then when turnd back on the line was gone

i posted a vid in the monitor section of what she looks like now just need to adjust the sixe and pos a little and it will look as good as new
