hi guys...
this is a vary weird situation that i did not see yet,so im hoping that someone will have have this experience before and have a solution.

so on this tv when power on,everything is ok,video display is nice,menu is nice and clear,this tv is working like it is supposed to be.....

but as soon as i plug a input source(hdmi,comp,vga....)and start to play it.the picture come with a lot of vertical white lines all over the picture,but sound ok.and even when i bring it on youtube everything is perfect until i press play on a video youtube.....here are a series of pictures of tv working....

picture 1 is when tv is on(all ok)

picture 2,2a is when tv is playing on pictures in sony software in menu.(all ok)
picture 3 is when tv playing music software in menu(all ok)

picture 5,5a,5b,5c is when tv playing input in the back panel(hdmi,comp,vga,ect)all of them doing the same thing.even on youtube when pressing play on a video movie,ect...(that is when the lines begin)

and pictures 4,4b, is when i bring it back to menu,info,ect...(all ok again)

so where can the problem be....t-con,screen or mainboard....and i did forgot to say that i did updated the last software from sony for this tv.

hope someone can help me out.

Well , i think that this is a mainboard problem. What happens when play something from a USB?

start with easiest thing first, Source, check another monitor or source issue, HDMI cable, Check cable on another set also.

thanks for replying,like i did explan,all input does the same(have vertical line all over the picture)but at soon as i go in menu and put photo screen savers,or anything that is in the menus will have a very nice picture....when i go on the internet like youtube....picture is perfect until i press play on any video so there are no more input since it is wireless.....

that why i do say the problem to be weired.......

i will have photo of board later tonight post for you....

i was guessing t-con board,but picture is good on menu,ect...

so i was wondering since mainboard have somekind of pre-loaded photos,ect...could when a video signal given in anyway, affect screen this bad.....
