    2 seconds to black on HNC IH252HPB

    Hello everyone. My monitor started acting up at maximum brightness last week. When I turn it down to 20% or less, it can stay on with no issues.

    I opened it up and tried flipping the jumper from 7.5 to 8A, but it made no difference. Even though the caps looked fine, I replaced all but the largest with good capacitors. I turned it on, and it did the same thing. When it's cold, I can get a picture for up to a minute. During that minute there is occasional flickering before it's black. After that, it's 2-3 seconds and it's black. I also should note that I tried hooking up a spare CFL in place of each of the four. It did the same thing leading me to suspect the inverter, but at this point I'm out of ideas.

    I'd very much appreciate any suggestions.

    Dell u2311h 20000 seconds to black issue
    by ChIck3n
    So I've had this monitor for probably a decade now, and it's finally starting to fail. Began with a little sporadic flickering, then eventually started going black (power LED stays blue, can still see image on screen with flashlight). A power on/off fixes it for a bit, but then it happens again. Once it got to the point I was dealing with this every few minutes, I opened it up and just replaced all the caps (minus the big one) on the power board with new Panasonic ones. All the old caps tested fine on an ESR meter, and this worked for 5 days. But the screen just went black again today, so...

    LG 37LG5020 and the tale of 2 seconds to black.
    by DrankinSAW
    I bought an LG 37LG5020 with a very strange issue.. it turns on, the display looks fine, but still, after 2 seconds, the TV shuts the backlight off..

    However, if i leave it plugged in for 20-40min.. the time it takes to shutdown the backlight, doubles (to 4 seconds)..

    I bought a new inverter, set to arrive on December 13th
