Can I test a TV screen without a working main board?
Hi, I recently came across a broken LG 3D TV, after plugging it in I received a black screen and no audio, but the power on light was white as if it was on. After taking it apart, I found the main board had some chips removed (likely from an attempted repair.) I'd like to have it fixed but the TV is worthless if the screen is cracked or otherwise damaged. Is there a way to test the screen without a working main board? It is the LG 55lw5600 if that helps any.
Es esta una buena pregunta?
