    did you remove the shield, and apply flux?

    usually takes me a good 20-30 minutes to remove those shields as there soldered on pretty well

      yeah removed shield

      then covered all board apart from where the shield sits

      applied flux allowing some to run behind the chips

      then was in over ( pre heated ) for 15 min

      strange this was tho i put it back in while it was still very warm - but it didnt come on it did the same thing

      i have now put shield back on and tried again still the same cycle

      now the hair dryer took longer but it seemed to come on again when i pointed it lower ( just below the shield )

        Maybe it's not the processor - where are you pointing heat at?

            its hard to tell as alot of things get heated up at once but just below the shield

              Yes, they are electrolytics and can fail in the same way as regular electrolytics on a power board (nothing different about them except the case.)

                there are multiple caps surrounding it, If you remember i asked you about smd caps a while ago that i didn't know what the part numbers ment.

                could it be those caps?

                  when I last done it i let the flux run everywhere in that area, but my fault was not as bad as this as it would restart after 2-3 hours of use, whereas yours is instant.

                  i've had one previously too that couldn't be repaired, still sitting in my cupboard, probably a new board is needed

                      when i get it going it then stays on and the heat shield gets very hot as the processor is running

                      but if i turn it off i cant get it back on again so something is cooling down - ( but the processor makes its own heat and in fact gets hotter )

                      it just went off again and i tried heating towards the bottom right just to the left of the turner and it seemed to come on quicker

                          yeah in that general area - nothing to lose baking again but this time let more of the board get the heat, i dont think the prob is under the shield has something to do around the shield as they are the bits that cool down again.

                          If i found a board for £15 i would get it but iv seen that some have gone for like £50 and thats way too much

                            went off again and tried heating the caps near the power connector - no change

                            then when i heated the caps around the turner it came on so im slowly narrowing it down

                            so tom66 the electrolytics can be replaced ? can i just get them from maplin ?

                              You can buy those capacitors from CPC with free next-day delivery on ANY order... Maplin caps are terrible!! Take a pic or highlight each suspect cap.

                                when i apply heat in this general area the tv works until they cool - so is there anything there that stands out that i can replace - or am i wasting my time

                                  Try narrowing heat down to just those 1000uF 10V caps - check voltage across them while working and while faulty.

                                    tom with these type of caps can they be replaced with ordinary leaded ones room permitting.

                                        You may want to check the back of the board as well.

                                          ok re bake still the same not much i can do apart from change a few caps only a few £ gamble so going to give that a try

                                          my question is some read 100 16J - so i take it they are 100uf and 16v

                                          but others says 100 16F so are they the same just a different size ?

                                            by tvguy12012012120
                                            This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.

                                            Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today....

                                            Samsung UE46f5000AK Stuck on Standby
                                            by Ukdigger
                                            When the Main board is disconnected, the back lights are off but tapping on the chassis makes them light up and all voltages are then good. Connecting the main board up makes the TV work normally until moved. LED INERFACE STRIP BN41-01971A has a short on the first 2 pins on the left of the picture, the cable tests good. All the other pins and all LED strips test good. Is there an easy way to fix the short or do I need a new interface. Any help would welcome.

                                            Samsung 60" Plasma TV, Blinking Standby LED
                                            by rju
                                            A sports bar/restaurant with ~40 Samsung Plasma TVs. This is the 2nd TV that has a blinking standby LED. I'd like to learn how to repair these TVs because I'd guess that over time more and more of them will develop this symptom. My hope is to repair the bad PCB, however if that's not realistic then I'd replace the bad PCB.

                                            Upon applying power, the red standby is steady. When I tap the power button, the standby LED immediately blinks twice, then it blinks once ~ every 4 secs. Also, Upon applying power, the...

                                            Samsung UA39EH5003R Stuck on standby
                                            by Rusenga
                                            Hi techs, I have a Samsung ua39eh5003r which switches on and then goes to standby. I have to wait for a day or two for the tv to switch on again, all the time it is stuck on standby. I have checked the voltages on the power supply board on both occasions when it is on and off and these are my findings:

                                            Connector CNM803:
                                            TV ON
                                            Pin1,3,4,5(Vamp),7(Vamp)- 12.6V; Pin2(PWM_DIM)- 0.96v; Pin6(BLU_ON/OFF)- 4.41v; Pin8,9,10- grnd; Pin11,12,13- 5.16v; Pin14(Power ON/OFF)- 3.3v

                                            TV OFF
