why does my tv picture turn off and on by itself?
HLR 5067W DLP TV, about 5 years old. Periodically picture will begin shutting off and on upon startup; when picture is on unable to adjust volume and HDMI indicator is onscreen, unable to switch inputs. Picture will stay on for about 15 seconds, then off for about 15 seconds and repeat. Unplugging and plugging TV/Cable power sometimes helps. Sometimes TV will not power up at all for several hours, then will work fine for several days, then picture will shut off and on by itself until it decides it's ok to run. During this time the lamp/fan are both working....have removed lamp and cleaned fan.
