I can't read the schematic. Too blurry to be sure where the Test Points are.
I'll venture a guess -
Looks like TP2 is on the output side of a bridge rectifier constructed of diodes CR1, CR2, CR3, and CR4 - check these diodes for continuity.
Looks like TP1 is on the output side of bridge rectifier BR1 - check this rectifier for continuity
