Hi,

I just brought used hotel TV model 23hf5474/10 without remote. First when I switched it on at home, it seemed to be working and I could access menu (using buttons on top of TV), but from about 3rd time when I switched the TV on, it only showes black screen. I've tried pulling the plug out of wall for several hours etc, but still I see only black screen. Any ideas what could be wrong?
