Samsung has a known power supply problem which it was the subject of a nation wide recall. Apparently earlier models had bad capacitors in the power supply, Google or check E bay for Samsung capacitor fix or recall. After 5 months my 6370 would occasionally turn off then on. Samsung reps had me unplug the TV while powered up to solve the issue, the TV then would only cycle on-off-on-off continually non-stop, only powering off if I pulled the plug. I also had a damaged screen issue that resulted in Samsung deleting my remaining warranty without further assistance. Thanks to buying the TV on a Citibank card, I filed a claim and Citibank refunded my full purchase price. NO MORE SAMSUNG TV's, good picture while it lasted, awful to use smart remote, terrible customer service.
Sorry, there was a problem. Please try again later.I owned several Samsung TV and I have never had any issue with them.
Sorry, there was a problem. Please try again later.I believe I've experienced this behavior a couple times. If the TV and the cable box are both off and turned on simultaneously, there isn't a picture. I've gotten it to work by turning off both the TV and cable and then turning the cable on first, waiting a couple seconds and then turning the TV on. So far that works. I know that HDMI needs to sense that there's a device connected. It must be getting confused somehow.
