        yes music, gonna have a rough time getting a look at screen, only put some screws along the bottom, so this thin allinone panel deal is unstable, i ll give it a shot.

          guess i cant look at the screen, misplaced the screws for the legs, i doubt if theres an image tho, theres only .10 v on each side of tcon fuse.

            Does this seem wrong? checked this and there is continuity but no 12v on the ld board pin 9: I have 12 at 4 and 9, i measured between 9 and where it goes to ld board, there is 0v on the ld side, thats from cn6601.

              pin 9 on cn6601 go to LD boards pin 1 LOL.. check again

              but T-CON 10.V this is not normal you need to test it on the 5 pins socket on T-CON pin 3- 4- 5 recieve 12V from power boards direct

                my bad, i meant pin 1, i just followed the wire over continuity but no 12 on ld board, will check the tcon 12s.

                  checked the tcon 12s at 5 pin connector, 0v on all of them.

                              yes its still grounded out, took 2 bl-error wire and put it in 9 gnd, been that way all thru testing.

                                  the voltages are not there, 12 isnt getting from cn6601 pin 9 to ld board pin 1, and the tcon 5 pin connector has 0 v, one of the pins might have showed .10 volts like the tcon fuse does but thats what they are, tested 4 or 5 times.

                                    it must be that damn IC9107 is bad, I guess.

                                      you are the bad here... sorry.. this why pin 18 0V and this why no picture even panel power on was high at the IC .. you fooled me before your self,, this never being trouble shooting... its just kids play game.

                                        I wrote that it was like that at least 2 times.

                                          putting it back as original but i dont think it should matter because a lot of people fixed 4 blink with that setup, if it kept all the voltages low their tvs would not be working.
