Question about Samsung LE40R72BDX 40 in. HD-Ready LCD Television
My samsung LNR408D lcd tv turns itself on and off multiple times when it is first powered up, and seems to stop when used for more than 30 mins. It has done this since 3 months after purchase, it went in for repair and the PSU was replaced. After a few months it did it again, and this time the PSU and PCB were replaced. Now 8 months later it is doing it again, and is out of warranty. Can anyone help please?!!! I have the same problem, i thought it might be dust so i gave the tv a blast with the wifes hairdryer and it made no differance, so i tried knocking it gently in various places when the problem occured and you guessed right it doesn't make a scrap of differance. the problem happens a lot when the tv is first turned on but after an hour it doesn't seem to happen or if it does it's only once an hour, the annoying thing is that i am about 6 months out of warranty & the tv cost over a thousand pounds
Try to tighten all screw around the power Supply to make a better ground ...
