Working on a Dell 22" monitor I purchased from eBay. The monitor stays on for approximately 10 minutes, then goes dim. When it does go dim, cycling the power causes 2 seconds to black behavior. Leave the monitor powered off for a few hours repeats the ability to have it run for 10 minutes, then the issue reappears.
I've checked all the caps on the inverter board (Elite brand) with my blue ESR meter and all of them spec out fine.
I metered the blue caps near the transformers and got similar ohms between the two (secondaries, right?)
I DO have a few spares at work to check for possible CCFL failure, but I really don't want to pull apart another 22" panel that's in constant use unless I absolutely have to. These things are heavy and awkward.
My symptoms are similar to the ones described in this thread:
