    Re: sanyo no back ligth

    Can we get a picture of underneath the PSU, around that same area? The green side of the board.

              I am wondering about what looks to be a cut in the main copper there...running from C134 to the connector...

                  Re: sanyo no back ligth

                  Can you do a full in focus picture of the bottom of the board.

                  On Pic dco6937, Tcon ,near the connector to the main board there is a White fuse with 2A on it. Can you test it?
                  and if you can get at it when its all connected up can you test the voltage on each side - black lead on ground or connector metal case then probe each side of fuse with the red probe.
                  Please upload pictures using attachment function when ask for help on the repair

                            Pic is very good one of the best I have seen for some time.
                            If you pan along the white line in the middle to the hole
                            Just below the hole there are 3 resistors and next to them
                            C902 Just below that there is an odd bit of solder?
                            May not be doing any harm but can you check it out.

                                    OK, leave the TV unplugged.
                                    Put the connector on CN2 back in place.
                                    Do not have the connector plug in to the C6.
                                    Get 1K any wattage will do, connect the resistor between PIN1 (5vstby) and pin3 (BL_ON) of CN6.
                                    Plug the TV into the outlet, hit the power switch, the backlights should come on.

                                          That looks like a diode, not a resistor?
