Hi
I have recently bought a 43h4500 samsung plasma tv and everything was okay; fluidity, colors, motion, uniformity but after 150 hours approximately with celllight always at 12 or less and contrast between 84 and 95 , a motion blurring problem and some Dirty screen effect appeared.
I sent the TV to my local samsung tv technical service and they told me that there isn't any problem with my tv.
i get the tv returned, and i was always annoyed by the picture under HMDI satellite reciever use ( 50 hz), Clear picture and the great motion fluidity and depth sensation too that i got in the begining was lost.
So i tryed to resolve the problem by myself using the service menu of course
.
in First time i tried "APC speed" from the default "low" value to "fast" and the picture was fine like the first day but unfortunately, this setting is not kept after power off.
After this, i have accidently running "HDMI calibration" and the picture colors become faulty, dark colors become too dark and light one's too lighter, so i got unatural contrast.
I have tried an HDMI calibration with black/white pattern and i got "success" but picture colors and contrast was always slighlty faulty.
I have tried " EDID WRITE ALL and EDID Write HDMI" and now i have a blurry and ghosted picture even with my 50hz receiver (the picture is also like pixalated) or my pc 60hz signal with my too HMDI ports, i have verified "ER count" and i have found "HDMI Stable Cnt" at 1.
This "HDMI Stable Cnt" is always at 1 now, even without any HDMI cable plugged!
I'm afraid that i've done an inrriversible problem to my HDMI ports or anything else related to HMDI it in my tv ! have you an idea how to repair it ?
thanks
