I have a 3 yr old LG 47' tv, mod # 47LN5200-UB and the picture has gone completely black but audio is still working. It is not a cable issue because I tested a different tv on the same connections and it worked fine. Internet says this is a common problem with this modle.

Thank you (long belated) for the great and very informative video! I am diagnosing a 55LA6200-UA and would like to ask for your advice.Symptoms: At power-on, I get the LG cube (full screen) for about 1 second, then black. (No stripes or flashes.) Flashlight test shows me normal TV screen, telling me the T-con and main board are good, leaving the LED driver circuits (power board) and LED strips as the main suspects.So. I metered out both of the LED+ terminals on the main power board for voltage. With the LEDs connected, at power-on the the LEDs blink and voltage jumps to 150(+/-), then quickly recedes and settles at 'normal' of 85.5 volts. Then, with the LEDs disconnected, I get the same result.
I'm left with no clear indication if the problem is power board or LEDs.Any other tests I can do on the power board to identify the problem before I do a full disassembly of the TV?.
