Hi guys and merry christmas, i have installed a computer power supply cooling fan 12v, 0.25A on the back of my Sony KV36HS500 by opening a hole on the back behinde the flyback transformer,and using a external 12vDC power supply,this is because meny owners of this sets have to replace the icMZ3001D meny often,and i've red on a forum that someone suggested this to cool the D board.My question is instead of every time i turn on the set i have to turn on, and off the switch that i connected to the external power supply to turn it on and off, can i use the D board as a DC supply,i have the sckematic for my set and have a (CN9100 PIN1)that has 12DC, is that safe and doesn't put to much strain on the circuit,how i go about to know or test that you guys suggest to make before i go ahead connecting the fan there, do i need to test for amps?Thanks in advance.
