At eight years old, likley the power supply is failing. You can try unplugging for a1/2 hour and then plugging it back in to see if you get any power lights or hear any noise. If it makes noise for a second and then cuts out, it is very possible that the power supply has some bad capacitors on it. Depending on your level of technical ability you can either find another power supply or change the capacitors. If you look at the power supply, any capacitor that is bulging on top is bad. Really bad ones will look like they are leaking with a residue on top.

I have a 42 inch Dynex tv have had it for about 2 years now its starting to just cut off by its self. HELP!!

Try changing the input device to something you are sure works. Look for any loose contacts in RC jacks/sockets/Cable. If problem persists, please refer it to a qualified service technician.

You have problems with your power up circuits. It is more than likely a fuse blown in some part of the TV that is keeping it from coming on. Also almost everything from a Computer to a $10.00 Calculator starts up by running a self diagnostics test on it's circuitry and if it detects any problems it will shut down or will go into a standby mode. Your TV has detected a problem some where in the circuitry and went into 'safe' or 'standby mode'. As I said in the beginning it could be a fuse, then again it could be about anything. I'm saying fuse because the heating and cooling of the element in the fuse often leads to metal fatigue and causes them to open up. Check the back and see if it has a 'user friendly' fuse panel and go from there. Look for a 30 amp blade fuse [it will be green] and see if its blown. I think that model has a history of blowing that particular fuse. If not, and you are not experienced in TV Repair don't attempt to take the back off and fix it your self, because there's places in there that will fix you good. You will need to take to a reputable TV Repair shop. I hope it's the fuse and that this helped! dhgill1949

On many of these (I am not familiar with this exact one) you push the volume up and down buttons on the set (not the remote) at the same time and hold them for a second or two. Try this. Philips has a customer help line that can help you as well, but expect a long wait and much irritation.
