I have a 2013 LG 50” 50LN5400 television and it’s not turning on i plugged it in and the stand by light slowly flashes twice and then goes dark any ideas as to what the problem could be?
Hi @rley_k , Start by following the no video/no audio troubleshooting flowchart, from the service manual for the TV. This leads to sect. A4 of the fault diagnosis process which shows where to check the voltages on the power board and their expected values. As per the flowchart, if the voltages aren’t as specified replace the power board. If they are replace the mainboard.
