Question about Samsung HC-P4363W 43 in. TV/DVD Combo

1 Answer

Samsung HC-P4363W turning off

The picture shuts off but the unit still has power. the only way i have been able to get it back on is to pull the plug and plug it back in.
I am wondering if its worthwhile to get fixed.. I think its a cooling problem because it occurred more often as i continue watching it.
Any help would be great.
Thanks in advance

    I have the EXACT same problem with this tv. Just wondering if you had yours repaired and if so, what did it cost you?? Mine is progressively getting worse and VERY annoying i must have it repaired soon!

    My truns off also.

    So if the power supply voltages have drifted out of factory spec!

    What would the factory voltage settings be? I work on automated machinery and have to set power supply voltages up from time to time.

    Same Problem. My TV began doing this shortly after the warranty ran out, and got progressivly worse. If the problem is with the voltage settings, is there an easy setting fix?

My Samsung HC-p4363w have no pic or sound but the power red light is on

Try pushing the "source" button on remote or on the TV. Wait about 5 seconds, if no picture, push again. Do this at least 6 times or until you get a picture. With each push, the TV will look for cable input, dvd input, etc. until it finds your cable signal.

Also make sure your cable/antenna is hooked up and working.

If that doesn't work, hold down the "enter" button for 10 seconds to reset the tv to original factory settings. Then follow the on-screen menu setup instructions.

-please rate me. Thanks and good luck.

Hi I have a samsung tx32766 aprox 42 in tv that was manufactured in July 1999. It was working great and then a line came through the middle with no picture and it keeps shutting off. I'm just wondering if it is worth having a service call.

Power out

Start with getting power back into the set supply unit. Could be anything from a fuse to a regulator to a bad flyback transformer....accordianman
