I have a 57F59A. It stopped working several months ago (can't turn on). I took it to a repair shop. After several weeks, the tech there finally repaired it. He told me he replaced the power supply ceramic resistor, rect. bridge and traces. Now i can turn on the TV. But the picture is so dark. I have to turn the contrast to more than 80 and the brightness to 100 in order to see the faces in the video. Can you guess what's wrong? I am so disappointed. I really like this TV. I spent money to have it repaired but have to get rid of it. So sad. Can Mr. Bob or someone here kindly point out to me what might be the cause of it? Thanks.
