Question about Samsung TXN2745FP 27" TV
The TV has a strange powering off issue. It seems the longer the TV is unplugged, then when you plug it back it, the TV will work. I can only get about 4hours of use before the tv turns it self off. And to get 4 hours I have to have it unplugged for a couple of days. If it is plugged in and I attempt to use it every day then it will last 5mins to an hour before shutting off. Is there an easy fix to this problem? I have tried using fans to blow on the back of the tv, thinking it may be an over heating issue, but this has not effect. What are my options besides drop kicking it into the nearest land fill?
Too bad I didn't see this post earlier...it's probably OBE by now. Still, your problem is most likely a bad capacitor in the power supply. If you know your way around a circuit board, you can probably find the bad cap via visual inspection (bulging top, leaking electrolyte, etc.), and can replace it yourself.
NOTE: TVs have numerous high-voltage circuits, and large capacitors can retain dangerous charges for a long time after the electrical source is disconnected. DO NOT work on your TV unless you have the knowledge and skills to do so safely!! Otherwise, take it to a TV repair shop--this is a trivial repair for them, and it probably won't be too expensive.
