    Im quite sure you main processor is at fault, it is responsible for turning that booster on from what I can tell.

        Re: Samsung UE32F5500AW no picture

        I found that PHASE2 is shorted to GND maybe that produce all the problems. Maybe the shortage is in main processor. Is it ok to remove the processor and then check for shortage?

        Main processor is BGA type KL5T3067

            Well i removed the processor and shortage is gone, so i guess the problem was main processor.

            What do you think?

                Well, it looks like you narrow it down to the cause of the problem.

                    BTW, the FET201 that you removed, does it tested as shorts between the S and D pin of both MOSFETs?

                        I tested the FET201 for shortage and it is ok.

                        I also try to remove the main processor and put it back, as soon as i put back the CPU the shortage retrned

                                Yep as I suspected. Fucking crap these boards are, if only they heatsunk them devices these would have lasted. Unless you have a bga station you will need a new board you can find the processor though on google, I dont so I hope its only IC200 faulty on mine.

                                        You already tested the outputs for shorts already so you may be OK, if the upper MOSFET of the FET201 shorted out then it can dump 13V to the PHASE2 (2V Buck regulator) output and damage the ICs.

                                                                    - when it arrived, it had a picture for a few seconds
                                                                    - it keeps rebooting

When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                                                                    all voltages from PS are good 12v 3.3v and 5v

                                                                    whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

I was given this TV as due to a power outage of constant On/off of power to TV. The TV originally would just click on and off (Typical Reboot Cycle). I opened the back of the TV, and troubleshooted by taking the 96 pin LVDS off one at a time to see if I had a picture on either side. I finally fixed the reboot cycle by finding the error on the left side of the screen off connector CN 1301, and the TV would stay on. Further troubleshooting led me to the driver boards where...
