I just had a total monitor failure on my philips monitor. I know it
has been going for a while. It would intermittently have its screen go
in and out all of the sudden and make a crackling noise. This would
normally not last long and I could sometimes just change the refresh
rate and it would be all right. Well yesterday I turned on my monitor
and it made this angry high pitch noise and let off a puff of smoke.
Well this was surely not good. So being an inquisitive person I pulled
apart the case and found that on the main board there were 3 burnt
resistors at R869, R849 and one on the back of the main board that was
not labeled directly under T803. Through a magnifying glass and a good
flash light I could just make out the color codes and found the values
of the resistors to be 68 ohms and 37 ohms respectively. I then began
to smell the components and noticed that L802 and maybe L803 which is
adjacent to it, T803 smelled a little burnt but as stated above T803 was
near a blown resistor so this could account for the smell. My question
is could I just replace the resistors and have the monitor be good as
knew or is it as a suspect that the blown resistors are a symptom and
not the cause. Also does anybody know where I could get a new L802 or
ID exactly what it is. (L for inductor I think). Looks kind of like a
transformer though! Since it seems to be impossible to find the
schematic unless you shell over $50 bucks but that kind of defeats the
purpose of trying to fix it yourself.

Just so people know I am a mechanical engineer by training but have
always been into tinkering with electronics I have access to
oscilloscopes, multi-meters and nice soldiering iron. But I am not an
expert or even a novice but I do have good technical skills.
Any help or suggestions is appreciated.
