IIRC 2 blinks are over current shut down. This will almost
always be the horz output (HOT) & or flyback ( FBT). FBT's did go
often on them. WARNING IIRC most of the FBT's were shipped
without the HV lead & you needed a special tool to get the old
one out !!
If the HOT is shorted the horz drive transformer usually has
cold joints or the FBT killed it.
