                  This has made me decide not to bother fixing my 47ln5750.

                          That looks nasty. And you thought Samsung were the only ones having trouble with fires...

                                  We once had a toaster oven catch fire from the control unit while it was off. We contacted GE, they sent some one to our house to pick it up, they dropped off their best Toaster oven they make free of charge and refunded us the full retail price of the unit that caught fire. And it was 3 years old.

                                  Some companies take this stuff serious, not sure if LG does but might give them a ring?

                                          so what am i seeing, the pcb shorting against the backplate, or arcing between the tracks on the board?
                                          it's very uniform along the length!

                                              I guess there is no shortage on these catching fire... there are a few threads about the exact same thing in this forum.

                                                  It seems to be shorting the return trace out which is why thats burning up. Very odd.

I have measured the voltage of the mains and it shows some fluctuations, it normally stays at around 226v, but often (every few seconds) drops down to 218/219v), and the flickering happens exactly at the same time. I have measured this at the counter and with every appliance off, so it's not related to the house electrical system, but that's how it comes from the supplier.
                                                                      I know that the best solution would be to get a voltage...

                                                                      I have an adjustable dc power supply and was trying around 9 volts.

I bought this welder for temporary use while my supercapacitor welder was waiting for replacement parts. It cost only £24, though there is a screenless version available for £17.

                                                                      Performance: The absolute maximum it can handle appears to be 0.15mm of pure nickel. Reliability was not great - welds were very inconsistent, ranging from weak attachment to burning through the strip. However, I was able to build a 5S2P pack without losing any cells. It's a bit difficult getting...

To test it, i unplugged the bad flat ribbon type connector and plugged it a good flat ribbon led connector scrapped from a HP Pavillion 27cw (led strip with 60 led). Good news is the HP led strip lights up but not fully, in between there are about 15 unlit leds.(as picture attached shows).
