Question about Philips 47PFL3603D LCD TV
Occasionally when I turn off my 42" TV it will start to have a loud static sound coming from the TV that will not stop until I turn the Televison back on. I have had to leave the tv on for the last 5 days. Can you help, has anyone else heard of this problem?

EVERY TIME I HAVE SEEN THIS PROBLEM IT HAS ALWAYS BEEN THE SMPS...SWITCHMODE POWER SUPPLY CIRCUIT BOARD...THATS WERE THE NOISE IS COMING FROM...RELAYS ON THAT BOARD ARE BEING ENERGIZED WHEN THEY ARE NOT SUPPOSED TO...THE UNIT SHOULD REMAIN IN STANDBY MODE UNTIL AN ON COMMAND IS RECEIVED VIA THE REMOTE CONTROL OR SET POWER ON BUTTON...TRY REPLACING THE SMPS..JOEACE

It is your Y sus board. Most of the time one of the buffers goes bad and takes out the Y sus. If you do the repair.YOU NEED TO REPLACE BOTH BUFFER BOARDS also. If your buffers are bad,they will dammage your new board.If you have a multimeter you can check if the buffers are shorted.Check the upper buffer by placeing one lead to the first pin of the black connector and the other lead on the third pin.You should have 500 or more ohms resistance.If none,reverse the leads. If your reading is less than 200 ohms like about 70-120 ohms even reversing the test leads. Your board is bad. Testing the lover buffer is about the same,Just test the last pin,and the third to the last pin. same results apply. If you install your new Ysus with a buffer that is bad,it will short out the diode "D5018" on the Y sus.Near the upper black connector,or even short out the main IC.You can also have your board rebuilt, There is a company on Ebay. I have used them once. Worked great. And fast as hell..o delivery. Hope this helps.
