1. Figure 1 Cabinet Back Removal Protection Circuit This TV set has a built in power supply protection circuit It is provided to protect the TV set in case of a power supply circuit malfunctions When something abnormality occurs during TV reception the TV set goes to the stand by mode When an abnormality occurs during TV reception it causes pin 23 of the Processor to go continually Low less than 2 0V for about 2 second The Processor detects that this has occurred and outputs the signal from pin 36 to switch off the power supply lines Releasing the protective circuit and restoring power supply To release the protective circuit and restore power supply turn the power to the TV set OFF and then ON again via either the main power switch or the ON OFF button on the remote control This will work only if the power supply trouble was temporary If there is permanent trouble such as a damaged circuit power cannot be restored an
