HP200CD - trying to pry it open

[morzh]

...and I cannot.

Two screws in the back seem like the only thing that could keep it together but when I losened them and try to pull the back wall out, I could not. I was not willing to apply too much force lest the thing gets dented or otherwise mangled.
And teh screws did not feel like they go into something solid anyway. One simply becomes loose once turned 1 or two turns, like there is some nut in there.

SO...how do you do it?

This is what the service manual says:

those darn HP covers, always a fight, on or off,

possible paint bonding going on at the front of the unit,

just grab the thing and shake it over a mattress or something,

it will come loose,

then buy a 16 lb sledge hammer to get it back on after you replace the light bulb,

notice the dual output transformers, one low freq and one high freq,
