Question about LG 42LH20 42 in. HDTV LCD TV
Perhaps an easy fix. Remove the back of the flat screen. There will be a main circuit board visible. There will be several capacitors, cylinders with a cross hatch on the silver top. Do any of them look like they have a dimple created by expansion of the internal capacitor material over heating? If you see an expanded top...that's probably your problem. Get your solder gun out and replace that capacitor. You can order a new one off of Amazon. If yours is a 10 volt capacitor, consider replacing it with a 16 volt unit. Generally the electronics companies under design the size of these units. When you replace the capacitor take note of the silver band on the unit and where its placed in the two socket holes....there is a positive and negative hole placement.
