Re: Phillips 170B Screen goes Blank after 1-2 seconds

New tester arrived today, went though what that video did, but the inverters are fine, I have continuity though both of them

Continuity is not a sufficient test.
You need to measure the resistance of the secondary coil in each inverter transformer and they need to be within 3% of each other.
Post your results and someone will advise if ok.
