PANASONIC TC-26LX20 - TC-32LX20 - TC-22LR30 - SELF CHECK & SERVICE MODE ADJUSTMENTS MODE CHART - TROUBLESHOOTING CHART



SELF CHECK FUNCTION FOR TV SECTION
The self-check feature is designed to check if a particular component is functioning and it does not actually diagnose the problem .For example “Tuner Check OK” doesn’t’ necessarily mean that it is OK. It pings or selectively addresses that particular device via the I2C Bus to determine if it exists. The same holds true for the Global Core IC’s, the MTS, the Sound circuit, and the Audio/Video switches. However, it should be noted that the displayed results could be misleading by indicating that it is OK.  The troubleshooting section of these documents intended to provide the necessary guidance and assistance in the fault isolation of a particular problem and will serve as a diagnostic tool for troubleshooting.

SELF CHECK ACCESS
To access the self check mode:
Press the VOLUME-Down Button on the unit and SLEEP button on the remote at the same time.
To exit press any key.
