      There are people on eBay offering repair services for around $70. Out of 10 used boards I got on EBay at least 6 of them were bad. They send board with blown fuses and claim it worked when they shipped it.

        yea i was thinking about sending it to one of the repair services on ebay

        i have purchased several boards from ebay and only one was defective
        but i know not everyone sells working boards so i do think twice before buying from ebay sellers

            Re: Samsung PN60E550D1F no audio no image only red LED

            So I received the xmain and the repair kit for the ysus

            I dont think i will be able to replace some of the components
            They are really freaking small

            Any suggestions?

            Anyone in the states willing to replace these for me?
            Of course I will pay

                I disconnected the logic board to the ysus and now VE is 20.8v before it was at 10.2v
                This is with the xmain from shopjimmy

                                VSC should be -198 according to the label from your picture from TV. If only -45 then your Y-sustain still has problem. Try disconnecting both buffer boards from Y-sustain and verify VSC again.

                                      Your Y sustain board is still bad. You may have more bad parts then what the repair kit provided.

                                          I believe shop jimmy provided parts that based on their experience goes bad. You may ask their tech. support and they may provide you some feedback. Compare the parts with one you already replaced and see if new parts are still OK or they shorted. You may have bad panels and it may short your sustain board after repair.

                                            hi
                                            having problem with samsung ua55es6800

                                            tv had backlight on, sound working - responds to the remote control but no image.

                                            check tcon board - had 12v in but no other voltages present.
                                            when disconnected left ribbon cable - got back voltages and half image with lines and distorsion

                                            when leaving only left side connected - again no voltages and no image.

                                            put a tape on all (cd?! lines) on the left ribbon cable and got complete but distorted image (horizontal lines).

                                            kept trying to block less pins on the left ribbon cable...
