I have had my Sony KP-51 WS500 RPTV for almost a year now and I am starting to notice a flicker in the picture and it is very annoying. The flicker is not drastic but I fear it could get worse. I heard about certain serial numbers of this TV having problems so I made sure the one I bought did not fall in between those certain serial numbers. But now it is flickering and I was wondering what could be causing it and if its fixable. Who would I contact to get it fixed? The one year warranty is almost up. any help would be appreciated. Thank you.
