Re: Samsung 214T with bad caps and transformers
I use the CFL with little probe for quick check to see if the output at the lamp connectors are putting out high voltage pulse, it will not stay lit of course. I usually use the test lamps for testing the inverter, so it is just for quick test, I also use it for other circuits that generate high voltage.
You can also use this kind of lamp:

Home made test lamps:

The ESR meter is just some thing I experiment with using 555 Timer IC. I have SECORE LC-75, it just something for me I am playing with.
Here is the diagram and pictures I come up with.
