Re: Lg 60pb4dt-ub
I had this issue in a different LG power supply, for a 37" LCD. The switching regulator ic was going bad. It regulated the 5V down to 3.4V. I just ended up replacing the power board completely but I'm sure it can be fixed.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
