https://community.sony.ba/t5/other-tvs/kdl40v3000-screen-brightness/m-p/1448400#M17584 Hi,<BR />Our beloved kdl40 v 3000 has just developed a screen brightness issue. The tv powers up as normal but within 30 seconds it goes brighter almost like a charging effect or a capacitor charging. If I leave the TV off for a longer period it will stay normal for up to a minute before the screen drifts bright er and brighter. It is bad timing for us so close to Christmas so a repair is our only option. Could this be the main board.<BR />Thanks in advance and happy Christmas to all.<BR />Pat Sun, 08 Dec 2013 00:53:27 GMT homewadbound11 2013-12-08T00:53:27Z https://community.sony.ba/t5/other-tvs/kdl40v3000-screen-brightness/m-p/1448400#M17584 Hi,<BR />Our beloved kdl40 v 3000 has just developed a screen brightness issue.
