Hey all,
I've been scratching my head around a Samsung T220 which first had a "stuck" button behavior, kept cycling through all the "MagicBright" modes at the maximum speed it could. I was able to "fix" it by adding an extra pull-up resistor to the 1.8V on the KEY2 line. No more OSD popping up all the time.
Now, when I solved this problem, another one appeared. Now I'm having a strange slight blur on the image (looks like horizontal misalignment), which can only be seen on the image coming from the computer. Maybe 1 pixel only... It's not that it's slow, it is behaving fast, but the image is all blur.
I've tried both DVI and VGA, the problem persists.
Also tried with another computer, and the problem is there...
I replaced all the capacitors on the main board (scaler board), didn't solve.
The strange part for me is that all the OSD layer can be read perfectly and shows no problem whatsoever.
Can you help me sorting out this problem?
I have a scope available which I can use to test something at your will.
Thanks!!
