Yes, it shouldn't affect it. The proximity sensor works by emitting an infrared beam and then wait for the beam being reflected from a surface. If within a pre-determined time span, it receives the beam meaning it has reflected from a surface it'll turn the display off. Shadows or far objects will not cause this because the infrared beam will disperse and not concentrated enough even if it is reflected.
Most proximity sensors have 2 mini lenses which suggests the transmit-receive nature. EOS400D has 2 lenses below the viewfinder eye cup. So maybe the casing has partially blocked the sensor OR the sensor position has move such that the casing has blocked it. Or there's something wrong with the sensor.
Did you do a self-repair attempt to correct the speaker?
erm, i tried to slip my nail at right side panel, and closed it back. i dunno that it was so easy to open it, just a slight peek, buka less than 0.5cm. ada problem?
