looking for parts for a sitdown hydro thunder not sure would matter on these parts bezel for crt casters wheel driver board diago board

yeah ill replace it had to order it

guess there no more ideas? trying to undestand what would cuase the +b is so high 156 157 158 area with a +b so high will it cuase no glow? cause shut down? tested 901 and 902 as stat before one does not drop as it should . so ill try replacing that all resistors i have tested so far have...

old reg was bad but new one seems fine 504 901 is fine r908 is fine

i did check it it did not drop the range it should have so woudlnt it need replacing? did have a question how to test hot and reg transistors they both only have a 2 leg package so what would the casing be base ??? actually datasheet just answered the question.

ill see if bob has them

im getting 47ohm on r908 from the resistor calc its right Y V blk R Or all resistors look orig and none are burnt up ... putting it back getting 83 hfe on the x901 datasheet shows min 40 typ 80 max 250 83 falls aroumd typical range correct? as far as the diode setting and testing red...

knocking around if i want to try the reg in the working chassis to make sure its good or looking at the x901 as it traces back to b2 and b3 which go to both sides of the reg

ok put full rebuild kit from bob on thischasis and still have same issue flyback widthcoil fuses hot and regulator plus capkit and still getting 158 +b reading same as before i changed anything before asking why change it all width coil was broken both fuses where bypassed went ahead...

thanks for the clearification had them reverse thgoutht he regulator was next to the flyback and hot was where you check +b but make more since the regulator would be near power source and hot would be near the flyback

(2SC1106) is what i called the hot the ceramic is above it i was talking about ordered a rebuild kit from bob if i dont install all parts ill ahve them in stock lol

vert scrolling was caused by +b being to high 128 lower to 120 all is good horz scrolling caused beacuse there was no sync connected (hooked sync back up screen corrected) so on to the other 5 monitors I have not working lol ok other g07 i am having issues with +b is reading the same on both...

ok thanks for trying to help i figured it out seems some how on my test rig the !!!! H sync !!! disconnected _)@($)_$(*@_($*@$_(@*$_@($*! nothing like wasting two days all 3 where there but for some reason the h sync wire came loose from the sync wire on the jamma harness shakes head...

lates info with monitor sitting horz on desk I checked +b was on high side 128 i turned it down to 120 now i no longer get vert scrolling now i get horz scrolling i up the +b the horz scroolign goes away but then vert scrooling starts horz freq pot gets the scroll to somewhat stop but not...

figured out mine the issue with mine was +b was to high causing a vert scroll with monitor set horz position corrected +b then horz scrolling was caused but not having both v and h syncs connected to sync on jamma harness all 3 wires where installed black white and yellow but the yellow was...

pics of it scrolling? goes from me getting it to stop to in scan line a second and progresivly gets worse as it runs longest i have had it still is 1 min if you mean the resisters already replaced them .

having same issue even after cap kit and pot replacements

have tried many dif pcbs including black tiger aero fighters sf2 and ms pacman all have same issue and no issues with other monitors on my test rig so yes i assume its the monitor even with the assumption i still tired swapping harnesses etc. no help

have 2 fried resisters now after a sync waire swap shakes head either case looking to find values of r317 and r315 looking for schematics now lol

i havent done anything to other chasis no idea what others have done i would need to look at it
