Facing TV Problems? Ask a TV Technician.
I understand, TV model number will tell us what type of it is, LCD or Plasma screen which will help me to get related manual for troubleshooting purpose.
Model number can also be found on TV user manual.
Sorry, had to step away from computer.
55le5500 is model number of LG LED TV. Would you like to troubleshoot the problem by yourself and can remove back cover of TV to proceed?
