The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have a question about the Power Supply Board in a LG 32LN530B-UA that does not have picture or sound. I do not appear to have all the voltages on the P201 connector that I should.


So did you check out the various components involved in creating the missing voltages? Transformers, caps, diodes, transistors, etc. Did you get the schematic for the power supply and scope it out?

Things do not just fix themselves - you have to check and probe for clues.

LG 60PN6500-UA broken HDMI port and clicks when power on


It will most likely go away when you fix the board. I suspect there is a logic system in there looking for that port and is not finding it.
