I wouldn't try to lift the top cover of an OM-4 myself. The circuit board is crammed under the top cover and could be damaged/cracked if you aren't real careful and know what you're doing in removing and putting it back -- and the circuit board is not replaceable if damaged. I would have a professional -- like Camtech (John Hermanson) -- handle this for you. Since you only paid $23 bucks for the camera, for the cost of a CLA ($140 or so), you could have a good as new OM-4 for about $160+.
