This has to be the crappiest board I've had to work on.
WARNING - REPAIR NIGTMARE DEAD AHEAD!
Someone soldered 10 resistors in backwards (2 of which were the incorrect values) , used an NTE379 instead of a BU406D, 7924 was blown in half, 7824 was blown, both 1N4001's were cooked as well as both 5w 50ohm resistors and lastly a ground wire was loose. This has the original red flyback so before I order a new one I thought I'd post here.
So now knowing what I have replaced/fixed I have hit a brick wall and need help. I have no picture, no LED lit on the HV and the BU406D gets screaming ass hot. VR1 registers +30 and +11.00 while VR2 is spot on for -30 and -24. Deflection board works perfectly with other HV board I have.
Any help/suggestions greatly appreciated.
