The PC is just fine, been runing okay for a few years. The monitor however, has issues. It is an odd issue that might be a sign of future broken monitor. For no apparent reason the monitor will just power off, so I have to manually turn it back on and it is fine. Is there something I can do to fix this besides the warranty? I already had it repair and I don't feel like shiping it again. I kind of want to just open it up, learn how to solder and well, you know the saying: If you want something done right then do it yourself.

Does it really power off or go to standby?

  • If it's standby then it could indicate a problem with the display signal, either from the computer or in the cable itself.
  • if it actually switches off entirely then it is most likely a problem with the monitor's power supply.
    • If it's a TFT with an external power supply, then you could try to replace the power supply (but be careful to get one with a matching output!).
    • If it's a CRT, or a TFT with internal power supply, then it needs to be repaired or replaced.

Given the cost of new TFT monitors, I'd consider replacing the monitor.

The reasons I know, why monitors power off are:

  • Cable problems: The green color usually has the sync frequency and if that is not arriving well, it may let some part of the monitor think it is out of sync. Check if all cable parts are OK by plugging them out and in again.
  • Heat: It may be overheated and thus turns off. Especially the power supply section has such features. Reason could be dust (remove power cord and blow the dust out). If the place you use it has not enough air circulation (or sun shining on the monitor back), that could be the problem.
  • Dust: Overheat in one of the areas due to not enough air circulation. Removing the dust can help
  • Age Errors: Some Capacitors get bad over years and before finally dying the security feature is shutting it off. This would be a reason to be careful keeping it running
