NTSC and ATSC and that would depend if or which set will get the better signal. Also remember that off air is analog and the sets are now design for digital.

Two models of the 46 inch Sony Bravia have a screen flicker problem. On my 2008 model, starting from cold, it lasts for 5-10 min, on LHS of screen. The Telefix tech who visited said this is common with these models (46in only), a new panel is needed. Sony provides warranty on this fault for 3 yrs, so you do not need extended warranty to claim. Discuss your case with Sony or Telefix.

Yes this thing start happening to my tv too about 4weeks ago and this goes away in about 15 minutes. TV is only 18 month old and I donot have extende warranty. Please post the solution if someone has got it repaired. Thanks

I have the same tv with the same problem. My tv is about 3 1/2 years old. I took it to the shop yesterday and today they told me that I had a bad lcd panel and a bad FL1 circuit board. They also told me it was going to be $3800.00 dollars to fix. I am now on my way to buy another tv, needless to say it will not be a Sony. Sony knows about this problem and refuse to do anything about it. Good luck.

I have Sony KDL-32XBR9 and I have noticed a similar problem. When the picture is showing mostly black, for example during the ending credits of a movie, the TV will further darken the display. Once the picture lightens back up, the TV will adjust the brightness of the display back to normal. I just called Sony customer support and they indicated it was a firmware problem and they will be sending a USB device in the mail to update the firmware. Hope this helps.

windows dose not control any flickering unless the driver is being updated if thats not the case your flourecent bulb might be getting old inside the lcd!

i have the same problem on mine, my tv is only just 12 months old, in the last 4 weeks it had 2 new blocks put in as the tv was blue, it costing £700 each (under guarante for 3 years thank god) then lastnight the tv made a big bang then switched it self off and the sand by botton is now flashing red then green, i have to leave it 30 mins before i switch it on again then only last 10 mins before it does the same thing again, got sony coming out again to day to fix it, had it with this tv now hate it !!!!!
