Samsung 46EH5000FX TV may run okay for hours, days or even weeks. But then it may just turn OFF and then after a few seconds or maybe minutes it will turn ON. At one time it seemed that I could reset it by unplugging and re-plugging the power cord. But that only seems to work sometimes. I have also replayed the power cord to eliminate that as a problem.
@pinetopb intermittent errors are the toughest to fix since troubleshooting is difficult. I would suggest that you remove the back of your set after you unplug it and then take a look at the boards. Check for bad capacitors (bulging/leaking etc.) check for burn marks on the PCB’s as well as cable ends. Check for tears etc. Post some images of your boards etc. with your question. Use this guide Adding images to an existing question for that, it will allow us to see what you see, Update (08/12/2017) @pinetopb sometimes all one has to work with are little things like this Samsung UExxEH5000 Training Manual
