Hello,
I am from Germany, so I am sorry for my bad english.
I have here a Acer H243H Bbmid.
2 seconds to black. you can see the picture with a flashlight.
I replaced the caps on the supply board. It still doesn't work.
I left it for a few weeks. on a new test it worked with a whisteling tone.
I opened it again and then there was the 2 seconds to black again with that whistling tone. I got near with my ear and could locate the tone on the "red marked" piece.
before the monitor shuts off it is flickering as the whisteling tone is.
what can I do next to find out what is wrong?
Is it possible that the whisteling piece is broken or can it be another part which causes in the marked piece the failure?
