Question about Philips 20PF5120 20 in. EDTV-Ready LCD Television
I'm assuming that by blinking you mean that the led is blinking - if the screen is blinking then the problem is with the CCFL tubes and since these are very hard to find it will be cheaper and easier just to get a new tv.
The led is blinking in only 2 cases: 1 - when there's a command signal active and 2 - when the power source of the tv autooscillates.
1 - appears when: the remote is constantly sending a signal - easy to test, remove the battery; one of the buttons on the tv is busted and constantly on - the volume or the channel will be constantly changing, you would see that; the IR sensor or the processor from the tv is malfunctioning - you must open the tv and test it.
2 - an capacitor has aged and no longer does its job of filtering the current - you must open the tv to check and replace the faulty one.
If you don't have even the most basic experience in the tv electronics then it's time to call a repairman.
