your problem is intermittent if you are not a tech have some one repair your tv the problem could be in your power supply,or horizontal circuit where the high voltage is.it can also be your micro processor. good luck.
solution to Both our problems is this, call Philips, "it just so happens that we have a rapid replacement program for this particular system"-"there seems to be an internal electrical problem", so I'm sending it back to them.......
You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.
