I have a 32 inch Samsung TV that is only two years old. When you press the power button, it sounds like it it turning on and the red light comes on but the screen is black and there is no sound.


Main board is bad since it works with both video and audio. Ur backlights are ok so that omits the inverter board. And the T con board is for video only - since you have hassles with audio and video that leaves the main board. Do not think it is the power supply since your inverter board is powering up the back lights.

No Video Or Sound - Stand By Light Flashes 5 Times


If the tv was made before December 2008, there is a capacitor settlement from a class action lawsuit by Samsung. Supposedly (at no charge) they will send a repairman to replace the capacitors.

Can't turn tv on at all


Hey Deon, this is very broad and could be several reasons. First off is there power to the tv? Usually tv's, even when they are off, have a light on the power button on the tv panel. Forget the remote for now and push the power button on the tv panel. Does any light come on? If there is no light at all then it has something to do with power. Check your outlet and see if there is coming through there. Could a be a fuse. If there is power through the outlet but no power on tv means something wrong with the AC on the tv. You should then contact tv repair or send it in under warranty. Read no further if light does not come on.
If a light comes on then try changing channels by pressing buttons on the tv panel. Secondly, try changing the input. It could be possible that it is on a different input and therefore, seems like it does not turn on. At the same time turn up the volume (all from the tv panel) to see if any sound comes out. If there is sound and still no video then try to change the contrast and brightness through the settings on the tv. If you see no menu then probably the lcd panel might be gone. Then you need to contact manufacture/ tv repair shop or send it in under warranty.
