Yeah, you're most likely not going to find a replacement panel at a practical price these days. I got mine on eBay about two or three years ago, and it was for a smaller TV (26").

Thanks everyone for the inputs!
where can i get a cheap replacement panel, in what price range ?

Not economical - 90% the price of a new TV in most cases.

I'm going to say that you have a bad panel. I've worked on several TVs that showed vertical lines that would gradually fill the screen. I found a cheap replacement panel for one of those TVs, and it's worked fine for about two years.

This is purely unscientific, but Sony LCD TVs are notorious for panel and main board issues. If you've tried a known working main board, you probably have a bad panel. Do the vertical lines on the screen in your pic show up like that when it's first turned on, or do they gradually appear?

If you tried a good mainboard & Tcon then it may be the panel
their may be a fuse on the Tconn did you check

Re: Replaced T-con board and now getting vertical lines

i have checked by replacing the main board once.. the results were same!

Re: Replaced T-con board and now getting vertical lines

sir if the main board is bad(faulty), can the tv function properly ?
all buttons and sounds working good!

I would say so but I could be wrong may be someone else out their with more TV experience can suggest some more ideas?

Re: Replaced T-con board and now getting vertical lines

Even thou it may look like it's bulged in the picture and it's not
capacitors don't have to bulge to be bad I test all my caps to find a problem

Re: Replaced T-con board and now getting vertical lines

but they are not bulged, though it may seem in the pic!

Re: Replaced T-con board and now getting vertical lines

You would need a ESR meter that is capable of testing on board or take them out to test.
