    I have an HP LC3200NTV HDTV, can't turn on/off using remote control, but can turn on with power button on the set. Once powered on, no sound or picture, but the blue power (on) light stays on forever.

TV picture goes out after 10 minutes of viewing with popping sound


It can be a couple things. Something bad on the power board. Or the vertical output circuit. How long ago did you purchase the television. Your best course of action is to have it serviced.
If you need any information or other assistance let me know.
Thanks,
Lee

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Samsung T.V. goes on for 30 seconds then no picture


If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

In my case, the backlight flashed on for less than a second, then went out. Turns out the backlight inverter was bad. I replaced it (got mine at http://www.lcdparts.net/LCDTVInverterdetail.aspx?InverterOriginal=V144-001MSS) and everything works fine.

I have the same problem when switching component inputs. I also had a problem with the backlight going off after 10secs-5mins. Which is still being resolved.
