Grab a 2' section of wire and a car charger. cut the wire into two pieces - stripping all ends, plug car charger in, connect wires to neon wires and charger end.. If it lights up U3 is more than likely bad. If not it's either the transformer or NEON..
FWIW - I recently had the same issue and U3 was the issue on mine, however , I bought a transformer and around 10 chips and sockets ( U3 is famous on these machines so I soldered a socket in now its a plug and play ) ...
If you need a socket and chip or transformer - PM me and I'll send you what you need...
