Too less time to get the solder to get hot and to attach to the pins and to the pcb, you need to hold down a few seconds more to get the solder as a mirror.
I have a big problem with my Samsung PS51D450 TV I have a problem that cannot be seen I saw your video on youtube same problem I followed your repair the problem and I can't read the code of the 4-pin component behind the pcb I saw the abbreviations of the IGBT component could you help me understand the code? As in your video I have a short circuit on the capacitor
Hi: In the Samsung PL43E400U the FGD4536 is turned on and off by an OpAmp rail to rail D8698 of 8 pins. There is also an IRS4427 driver of two outputs A and B in phase with the inputs. This driver uses it to turn on and off two RJP63K2 You should see if any of these IC is the one that the teacher changed in the PN51D440A5D model.
