    Lg60PK750

    I have a LG60PK750 plasma tv. Tv works just fine for about 20min then shuts itself off. Tv will click and turn itself off, and will not respond at all with remote or buttons on set. All voltages are correct while tv is working. seems to me its heat related, any suggestions on what to check would be appreciated. Going to check for bad solder joints.

    Disconnect the connector going to the Y-sus Bd. Connect two 120Vac household bulbs in SERIES and connect them across Vs and GND on the connector. Apply the ac, the light bulbs should come on. Wait for the 20min time and see if it the bulbs go out or if the all other voltages Va, 12V, 17V. M5V, etc drop out on the PSU.
