55pfl5706/f7 wont power on

If the display panel has failed, it will be best to buy a new TV, rather than trying to make it repaired.

Philips 32PFL3505D/F7 32-Inch LCD HDTV keeps turning off when I turn it on

You have a shorted Diode in the power supply board.The power supply board has a 110 volt AC cord attached to it. Locate diode D621. It will be near the red, black and white wires attached to the inverter board. Snip this diode on one end and lift it just to clear the board. You may cut the other end and remove (don't have to). Do not try to tear the diode out or you will destroy the board. The TV will operate fine without this diode. Replace your ac fuse (4 AMP, GMA fast blow fuse ). You just repaired your TV. Thanks for asking, Matt of Martins TV.

I turn the tv on and after a few seconds it shuts itself back off again. At that point I can't turn it back on until I unplug it and plug it back in. However, when I turn it back on it will again turn...

Possibly the main Power Regulator is damaged!!!

Open the case, then look for anything that burned out, replace it!!!

If still won't start, you need a multimeter, soldering iron, try locate output diode on power regulator board, then measure the voltages, it has 3-4 type of voltages;
first diode it should around 115V-130 V DC.
Second diode it should around 24 V DC.
Third diode it should around 11-16 V DC.
Fourth ( if exist), check diode and should around 5 V DC.

The problems usually start on second diode, if persist, follow the circuit board.
