Question about Philips Televison & Video
Turned off, unplugged for extended period.
Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

It sounds like your High Voltage transformer is arcing.
Sometimes it can be repaired if not it is an expensive fix.
If you can see in the back of it look for sparks inside but do
not remove the rear panel, you can get zapped with 40,000 volts!

A local repair shop, recommended off ShopJimmy.com, repaired ours with the exact problem for less than $250 total. Inverters were bad. The parts were $50 each at Shop Jimmy so the shop dx'd the problem and repaired it for less than $250 total! Very happy.
Trick they showed us.... turn off lights in the room and shine a flashlight down the t.v. The picture can be seen which means it's not all the horrible problems you might think.

i was a tv engineer for many years quite a while back now and when a led is flasing or pulsing it usualy means the tv's power supply is in over current mode wherebye it shuts down to prevent any further damage due to a part of the circuitry drawing excess current, high voltage transformer etc, you need to get a techie in, sorry.
