If a multimeter in diode mode isn't sufficient enough to diagnose which LEDs may be bad on a TV, how can this be measured (without having to buy an LED tester tool)?
Or rather, perhaps a better way to ask is: how can one replicate the specific testing an LED tester is able to do without having an LED tester tool? And particularly when a multimeter in diode mode shows that every TV LED lights up just fine + every LED has the same forward/reverse voltages.
In another thread, neilc6 mentioned that a multimeter in diode mode isn't sufficient enough to determine, as it won't put out enough current and it there's some issue regarding "delay" that it won't be able to see. I'm wondering if these things can be seen using just standard/routine repair tools, like multimeter, oscilloscope, logic analyzer, etc.
