SELF CHECK FUNCTION FOR TV SECTION
Service & Troubleshoot to DVD part follows by next post:
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 IIC by determine if it exists. The same holds truce for the Global Core ICs, the MTS, the sound circuit, and audio/video switches. It should be noticed that the displayed result could be misleading by indicating that it is OK.
SELF CHECK ACCESS
- To access self check mode, press the "Volume Dn" button on the 'TV', and the 'Sleep" button on the remote at the same time. To 'Exit' this mode, press any key on the remote control.
