Hi everyone,
I've been lurking around the Badcaps forum for a while trying to find a solution to my Samsung 2493HM's intermittent death. Unfortunately I wasn't able to find a solution to my exact problem. I'll list my observations below:
-Screen suddenly goes black, this includes a loss of HDMI speaker output. This occurs both with video/audio from PC and PS3. The power light remains lit solid when this happens.
- If I leave it unplugged for a period of time it will work again for a period. I had it sitting unplugged for a few weeks and it worked flawlessly for a day and a half. Once it packed up again, a short cool-down was giving me 5-10 minutes use (or nothing at all)
- After leaving it powered on with a black screen, sometimes there will be a series of intermittent pops. These follow no obvious pattern and range in loudness.
- Occasionally after the screen blacks out there will be a loud screech and the screen will burst back to life. If I give the screen a good tap on the bezel I can force it to do this the odd time.
- A quick inspection of the power supply board by my not-quite-untrained eyes didn't reveal any bulging caps. I did notice what appeared to be burn marks around the edge of the logic board, but I'm no expert, so that may not be the case.
At any rate I'll crack it open again and take some decent photos. Thanks in advance.
