well im a huge monitor repair kick right now trying to get all my spare backup monitors going and then going to dispose of all the old burned tubes and bad chassis


right now im looking at the wg 4901 that was in my gorf
i shorted a ac wire onto the frame and now it will come up on inital power on (not long enough to show a pic ) and then shut right back down
i have a cap kit here for it
but before i do the kit just want to make shure its not a hot or other part that i do not have on hand (dnt want to waste my cap kit if it will not fix it )

my first ? is
how do i test the hot to be shure its good

second
what other components controll the hv circut on these as it seems im getting hv shutdown (i.e it comes up then shuts right back down )


thanks in adv monitor gurus (lol by the time i finish all these project monitors i should be a monitor pro lol )
 
ok where is the regulator located and is there a cross refrence for the regulator i have like 10 arts chassis here (lol none of wich are 4900 series )that i may be able to bull the proper regulator from
edit
im guesssing the regulator is ic 501

is the regulator a ic if so what is the cross refrence for it i can call up elect suply and hopefully they have one or get one from bob
like i said im tryig to go thrue all my parts/in need of repair monitors and weed out the ones that need to be trashed lol im running out of room here to store all these monitors

i have the 4900 manual pulled up but nothing is listed as the voltage regulator in the parts list

ok so after looking over the chassis and looking at the manual (and seing the vr list on bobs site ) it looks like either q302 or q303 would be the voltage regulator as i do not see any other transitors that looks like the ones in bobs vr kit other than thoes 2
