My new Loewe Mimo 32 has noticable patched of discolouration on the screen - especially on light backgrounds. They are most noticable at the top of the screen but the do extend don the screen about 2/3 or 3/4 of the way. There are two main areas, one on the laeft which apprears to be blue and on the right it's pink. Any idea what is causing this and how to fix it. I just moved my speakers away (curenltly about 1m) and removed my centre speaker but it remains unchanged. Might this still be too close to the sides of the screen?
