Anyone shed any light on this? Got a 3-year-old Philips 32PW9527 that's just started exhibiting strange symptoms: every now and again the picture disappears and an associated static-like 'pop' is heard! It's not loud like a lightning crack but it's there all the same. Sometimes, too, when the picture has gone, there's a brief R, G & B display in the centre of the screen. All this lasts approximately half a second and then all's back to normal.
