Question about Philips 32PT6441/37 32" TV
It depends on whether you are getting the picture on the screen before it shuts off.
If all seems well before the set shuts off, look for possible dry soldering in the board. You can use a solderring iron and solder possible heating areas of power related components.
A switch off can also be possible if an IC malfunctions but it might require a great deal of patience to see where the missing link is for the action to switch off.
So in the off state check the power supply voltages to the mainboard. Look for the +5 to the micropprcessor if the regulator is faulty with a lower voltage, check the filter capacitors in the power supply of all rail voltages.
However if there is no picture and sound then possible fault can be one of the processor IC's.
