Hi,
I have a Sony Bravia 46" LED backlit LCD (KDL46HX820) exhibiting vertical stripes which on occasion look like "haze", mostly over the left hand side of the screen. The colour and positioning varies slightly depending on what is being displayed.
This fault displays on any input, even in the menus and internet tv. Most of the right hand side seems unaffected. When there is a drastic picture change (ie: exiting the menu), the lines introduced by the previous image stay for a while and slowly fade out. Some text from menus is almost still visible after exiting the menu, pixelated vertical haze, which fades out after a while.
I have checked capacitors, reseated all connectors between the t-con board and the panel, and between the t-con board and the main board. The TV recently moved house, however had been working fine for a few months in its new home before this issue reared its ugly head. Just in case, I have checked the panel from the front carefully with a bright torch, there does not appear to be any physical damage to the panel – although it is difficult to see it perfectly through the gorilla glass. I am suspecting it may be a faulty t-con board, but the “temporary burn-in” effect sometimes makes me think it might be a faulty panel?? Your thoughts, anyone?? Any help would be greatly appreciated.
Attached are a few images:
* image01.jpg shows part of the screen not long after power-on, displaying the ABC iView menu. You can see some (but not many) red vertical lines through the image. The rest of the image is pretty good at this stage. As long as it has a constantly moving image its not TOO bad, but annoying nonetheless.
* image02.jpg is on the input select screen, with an untuned analogue station displayed in the preview window, you can see the "temporary burn-in" effect from the previous ABC iView screen with some almost readable text still there. 20 to 30 seconds or so after that it did fade out completely.
* image03.jpg is same as image02.jpg but a wider view to show the effect on the whole screen of the snowy preview window.
* image04.jpg is back on the ABC iView screen a short while after being on the other picture for a while, you can see the left overs from the white snowy box in that part of the screen, still fading out.
What do you think? panel is stuffed? or is it worth trying a replacement t-con board?
