i have a samsung PN42B450B1DXZA plasma television, 42" bought about 3 years ago.
i dont know if this is a cable issue or if this is a tv issue. i called the cable company and they spent about two hours doing tests, replacing the cable box, new wires, checking the pole outside, etc. as soon as they left tv went black while watch regular television.
when i watch my television, it goes black randomly. sometimes its after two minutes of watching tv, sometimes its after hours of watching tv. in order to get the picture back i have to shut down television, wait a few seconds then turn tv back on. sometime picture immediately goes black again, sometimes it will be hours before it goes out again.
i have tried using an HDMI cable, but no luck. perhaps i can try a better more expensive HDMI cable.
can anyone offer suggestions on what the problem might be.
**just as a note, when the television goes black, i cant access the television's menu.
also, should it matter whether the cable signal is 1080i or 720p? i think my tv is 720p.
