Dali netko iz slike može potvrditi dali je ovo taj murra efekt i dali postoji, i ako da, koje bi bilo rješenje za taj problem.

Bijela točka je odsjaj blica sa aparata. Problem je u tamnim horizontalnim oblacima.

Moze biti a i ne mora...zavisi koliko je uredjaj star i u kakvim je uslovima radio, procitaj dalje:

Ne bas uvek, ali ima istine i u tome - desi se da se mikroprasina natalozi na i izmedju disperzionih plasticnih filtera koji se vremenom polarizuju... ali problem je najveci kad se stakla koja cine sendvic displeja krenu razdvajati od toplote i loseg kvaliteta lepila (tip 3)...displeji se klasifikuju od A+ do B- u toku iste proizvodnje tako da gledajte da imate srece kad kupujete jedan B- klase (uglavnom su najjeftiniji)...
Mi, na Balkanu taj nedostatak na displeju zovemo strucno "mrlje na ekranu"

Mura Effect type 1 corresponds to a lack of homogeneity in control circuit adjustments. From one cell to another color control can change and it will lead to permanent defects in intensity in displayed images.
Mura Effect type 2, or Cell Gap Mura comes in two forms. If liquid crystal cell sizes are superior to the normal size in an area of the panel, the images produced in this area will be brighter. This is a White Mura. In the opposite way, if the cell size is too small, it will be darker. This is a Black Mura. Cell distortions sometimes come from a « normal » defect in manufacturing, but most of the times are due to an impurity in the panel such as dust, a drop of some chemical or an accidental ionisation of liquid crystals, which then misalign. For the first two cases, it is possible to move the defect by gently pressing the panel with your fingers to move the Mura to the side from a useful area in the screen. In the case of ionisation, the defect can fade or even disappear with time. For us it was the opposite with the appearance of a Mura on two monitors after a few years of use (three and five years, respectively). It looks as if you were pushing on the screen with your fingers except now it´s permanent.
Mura Effect type 3 is related to distance or defects between the panel and liquid crystals. This occurs when the panel is sealed and side pressure is imperfect. If it´s too strong, cells are crushed and there is a bright halo in a corner along the panel.
These are the three types of Mura effects detected in the factory. Two others exist:
One Murat effect can appear when color filters (red, green and blue) placed on cells are made of different materials, which react differently to heat and light,
the next one can be included as a manufacturing Mura, even if it isn’t one. The “spot” is a mark on the backlighting itself. It doesn’t properly light up an area of the monitor and causes a small spot of 1 to 5 mm in diameter.

Samo da izvjestim, pošto nema jednostavnog rješenja, prijatelj, čiji je tv, odlučio je da nabavi novi.
