Phillips 42pf5521d/10 Buzzing when on whites.
Had a few plasma's in this week 1 Hitachi with bad contacts causing lines on the screen, 1 Samsung full of failed samxon gf and finally this one the phillips 42pf5521d/10 that was having shutdown and standby issues repaired by replacing a few of the smd capacitors and the set returned to normal, but im still not happy with it and don't want to send it back to the customer this is the first time and hopefully last time I come across this issue when the screen is displaying large portions of white there is a loud buzzing noise coming from the psu I can sort of determine where its coming from (one of the smaller transformers next to the switching section). I have read up that it could be due to thermal expansion on one of the components but it does it when the set is cold and when its warm after being on for a while, any ideas I will upload some photos of the psu when I get my camera back. Any feed back would be much appreciated thank you.
