He may be right, LG is used to be called GOLD STAR, which makes junky electronic products, they changed the name to make it sounds better.

The backlight is out most likely caused by either the T conn or the Invertor. The invertor is most likely you can get replacement boards from www.tvcircuitboards.com leave a email if your not sure what you need.

Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electro-medical.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board..

Can you tell if LED tv has bad LED strips before changing LED Board/Power Supply (as they're in one piece on a lot of TVs)?


This is not easy to diagnose, either use a meter on the power cable to the led or check the leds one at a time
