45a656 problem

[ugur466]

hello i have 46a656 (s2) i updated my tv via usb from prl1015 to amb1023 and my tv doesnt work properly,a few days it displays perfect and a few days it displays fuzzy.in both hd satellite receiver and dvd player. while fuzzy, as if the machine (processor) doesn't work properly. i updated several times to 1023, i went into sm and changed dyne dimm on-off and on-off changed dyne ce off-on and off-on but didn't work, i dont understand why is it so? can i fix it? .while fuzzy, as if the machine (processor) doesn't work properly because: it displays every detail even cells in human face when its good but other times does not,as if wide color enhancer doesn't work.thanks in advance
