I have a Hantarex Polo 33 inch monitor that went down over the last weekend. There is an audible clicking sound that seems to be synonymous with the over load protection circuit kicking in. I metered the BU508A and get a .5v voltage drop in diode test when I meter from the B to C and B to E, leaving me to believe that the transistor is good. I found a bad cap (c181), but it was not shorted as it had a terrible ESR. I rang out the FBT and all pins rang out in perfect form so I do not expect the FBT to be the cause of the problems. With the yoke windings plugged in the B+ reads 60-90 VDC, but when they are disconnected I get a solid 138 VDC. I did find a cap of some sort that was mounted on the soldier side of the board to be broken off of its pad. It was mounted in between pin one of the FBT and Some Diodes mounted to some PCBs standing up (d147 I think).
I am kinda stumped here as I have tested all of the caps via ESR meter and really only found one truly bad cap. I found a handful of possibly cracked/cold soldier pads and refilled them but I am still at the same place. Any help would be much appreciated.
Cheers,
ZMB
