my LCD tv (LG 42LN5200) has sound and backlight but no picture. I turn on my Xbox gaming console and I hear it turn on and everything with no issue there is no discoloration on the screen just looks like it's on. i was on my phone when my tv just shut off but the backlight and sound was on I thought it went into sleep mined cause this usually happens, I proceeded to turn it off even the power block for 15 mins and still the same problem. I opened my tv and all 5 capacitors were ok none bursted or are bulging out. I tried the flashlight test as well and see no picture so I doubt it's the inverter. if anyone can help me out it would be greatly appreciated I rather fix this on my own than buy a new tv if the price range is right.
