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

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

                          and if main board is at fault, can the tv switched on, and all sounds and buttons are working fine ?

                            capacitors don't have to bulge to be bad I test all my caps to find a problem

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

                                        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?
