I am in need of repairs on a 33 inch Polo chassis. Swapped the flyback and the HOT, it went from dead to working for a few seconds then shut back down. I have a Revolution X waiting to find itself a temp home in a bowling alley. Prices for repairs?
did you install a cap kit? I mean, there's a lot of weird stuff that can go wrong with these.
you have a volt meter? test the B+ at TP6 (it's at the very front and center of the chassis facing the side by the tube, with the monitor off try prying it up a little bit so you can hook under it with the red probe, and you stick the black probe of the meter in one of the holes in the big heatsink on the right for your cold ground)
verify that you still have the insulator on the HOT, it's like a bluish grey texture. pull the HOT and test it, if it blew again then you have some other issue and I would advise sending to www.arcadecup.com
