Having problems with your Flat Panel Televisions ?

42PFL9900D/10 Philips LCD Television Hissing Speakers


\015 Hello, I bought this TV from a mate for a steal. Everything is perfect apart from a hissing whining sound which can be very loud and high pitched after an hour. When I mute the TV the hiss/whine is gone so I suspect leaking capacitors. The hiss is present on HDMI & scart. The hiss isn't there on audio out. I can mute and use the audio out but the mute icon doesn't go off the screen! The hiss is louder and a higher frequency when Ambilight is turned on. I have a background in electronics and can fix this if the problem is capacitors. Has anyone else had this type of problem with Philips TVs and can point me to right board inside. My other alternative is put a switch on the internal speakers and use audio out. The hiss is only noticeable if the TV is turned down low or very quiet scenes. TV is running the latest firmware version. Thanks all, Chris.\015
