The power supply regulator section is not working properly. It will be best to replace this board as card basis rather than trying to make it right. Philips have used some special numbered components there, which are very difficult to get from open electronic spare part market. Contact the nearest authorized service center for Philips to buy a new board.
u can buy power supply testers, just a device you plug the power supply into, or try a new power supply. but if nothing is happening no fans etc theres a good chance its just the power supply.
