Fault analysis: TCL plasma TV PDP42U6-L This machine has a malfunction. The red light is on. Press the remote control to turn on the red light and then the blue light. No image or light. Test the power board VS / VA all output is normal. The sustain drive voltage for testing the sustain drive output is 100V normal. The VSC of the test scan board is only about 0V, and the normal one should be about 100V. Disconnect the two adapter boards and find that the fault still does not rise. The VS (190V) voltage output from the power board has a downward SF2 test, and the IC15 VS input pin is shorted to ground. Replace FS2 (4A Insurance) IC15 convergence amplifier troubleshooting.
