Bargain indeed. I decided to use the meters to fix each other, just for the hell of it.
7732A (no backlight) - Supply VB+ and VB- ok. LEDs light up using diode test function of 7730A. No continuity between the series LEDs despite PCB track and solder joints ok visually. A dab of flux and re-solder and jobs a good 'un

7730A (missing segments) - looks like 4 segments are out (3 on the top left digit and the minus sign). This indicates a single connection as LCD is 4 way multiplex.

Tracks and solder pads to the driver IC's all looked good and buzzed out ok. God awful slow continuity tester. The zebra contact pads on the PCB looked a bit tacky from whatever glue substance they use. Cleaned the pads with IPA and re-assembled.

In contrast to
Daves UNI-T UT71E teardown these meters are fitted with HRC fuses. They even kindly provide spaces to mount 3 of your favourite MOVs instead of the spark-gap customization option on Daves UNI-T.

Thank you Ian. I look forward to more dodgy customer return fixer-uppers from you in the future!
