Well, I found this TV/monitor in the garbage yesterday, not as scratch on it and it works...
The problem is that after running for a while (could be 3 minutes or 2 hours) it flickers (entire screen - no artifacts) and goes black - if I turn it off and on again, it works for a few seconds and then goes black again. I'm using it as a computer monitor. I've tried HDMI and RGB connections and the RGB surprisingly gives much better results. The quality is unexpectedly good actually. I did open the thing (tricky) and tried to unplug/replug the connectors, since it really looks like a contact problem: screen warms up and fails. (Runs longer when cold).
Now my idea is to try to re-flow some soldering joints, but it might be a capacitor issue too from what I've read, but wouldn't that cause digital noise?
-any thoughts from the more tech-minded is appreciated
