Question about LG Televison & Video

1 Answer

Can you help determine what the problem may be with a 32" LG TV that has no picture ? We have a model 32LN530B-UA. s/n 308MXVW8E535 SVC code 32LN530B-UA.BUSYLWM

It has no picture. It has audio. It has no back lights - I took the back cover off. I used the flashlight with the lights off and was able to see the words from the menu screen. I'm not sure what other tests to try.

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. 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.
