This tv have a problems with a board that call T-CON decodering board.This T-CON decodering board sit at the bottom in the middle of the LCD screen panel.This T-CON decodering board,decodering the tv incomming broadcasting tv signal before it go into the tv LCD screen panel to produce pictures.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.
This is common issue of the channels that use 4:3 format while TV is designed for 16:9. To get it disappear, you just go to picture option, choose WIDE FIT, this fuction will widen the picture to whole screen. Of course, you have to accept the picture is blur a bit.
Firstly, to get a "Shop" standard picture, you need to have a true HD feed. Usually a demo disc filmed in HD at 1080p, played on a true HD system at 1080p into your TV. Most broadcast feeds at present are on 720p.
However, you can improve the picture significantly just by changing a few settings on the TV:
Contrast: Change to about 65% of maximum. Too much
contrast gives a blurry / grainy image.
Sharpness: Change to about 20% of maximum
Also turn of any dynamic or digital contrast settings on the TV (if it has them)
