Compaq R3000 series LCD Display info - help me change out my inverter please.

I have in my hands a Presario Laptop (R3000 series) R3410US.

The display has dimmed out (gradual failure) and now has NOT backlight at all.

I feel confident the issue is a failed INVERTER and i can ONLY assume that the
inverter is located inside the display (lid protion) itself.

I've downloaded HP/Compaqs Service manual for the product which
is very helpful with the assembly/disaasembly of the product, however ...
I does NOT deal with servicing the guts of the display.

Does anybody Know FOR SURE that the inverter IS infact located inside the "lid"
(display itself) and ...

Do you KNOW for SURE how to get the display OPEN without breaking it?

I find NO screws of other fasteners accessable to open the "lid"
but HAVE in my hands the replacement inverter, but the HP/Compaq
documentation is quite useless for this step, since it doesnot PICTURE the
part or it's location, nor does it go into the "how-to" of changing it out.

Any thoughts?

Please and Thank you oh so much.

As I said in my original post...

I've already downloaded (and printed) the service manual
for this product (I should have specified -> c00212209.pdf)

So do I get points for solving my own problem?

The answer(s) are:
  1.) Yes the inverter lives INSIDE the lid with the display
  2.) the bezel cover screws are hidden under "bumpers"
       at the 4 corners of the display.
  3.) the part number specified in the HP manual is wrong
       ( or they've incorrectly packaged the part they sent)
       the part works fine electrically - but will NOT mount
       on the provided display mounting holes so it must "free float."

The inverter is allways in the display lid area. The reason for that is that it creates high voltages which are hazardous. Such voltages should be kept to a short distance to reduce the possibility of the wires getting into contact with things they shouldn't touch. Another reason is that if the cables needed to pass through the display's hinge which allways moves that would increase the chance of the wires breaking and that would also increase the potential of shocking the user.

Do you like bad hair days?
You are 'free floating' between 900 and 1300 volts DC in your lid.
Not a good idea....

Have a nice day.
