I purchased a LG EAY64269401 for a 55LW340C-UA-BUSWLJR due to the R LEDs being dead. While t-shooting, I swapped the leads between L and R and the L was dead. This told me the R LED driver was bad, hence ordering the PS. Once I installed the replacement PS, the set worked great, but after about 10 minutes the R LEDs were dead again. I pulled the screen to see the first 3 LEDs on the strip are internally burnt. I have located replacement LEDs and ordered. Do you have any recommendations on repairing the PS PCB I just installed? I do not have a schematic for this set. Thank you - Mark
