Philips GR-8 movement, with multi-standard receiver, NICAM system, graphic decoding system and multi-channel stereo sound selection. Philips GR-8 movement Applicable models: Philips 28GR6776, 28GR6776H, 28GB6776B and other models. Philips GR-8 movement switching power supply using discrete components, vice power from the main power supply, standby power supply to reduce the switching power supply output voltage. The movement around the standby control circuit, set up an analog thyristor protection circuit and 140V output voltage overvoltage detection, 32V output voltage overvoltage detection, protection forced standby
