MAIN SOFTWARE UPDATE In MB98 project, please follow software update procedure: 1. mb130_en.bin, mb130_RomBoot.bin, mb130_PM51.bin and usb_auto_update_G10.txt documents should be copied directly inside of a flash memory (not in a folder). 2. Insert flash memory to the TV when TV is powered off. 3.
  • Page 41 Dimming pin should be high or square wave in open position. If it is low, please check S122 for Mstar side. It also can be checked at TP106. Please also check panel or power cables and connectors. Backlight power supply should be in panel specs. Please check Q124, shown below; also it can be checked TP112.
  • Page 42 STBY_ON/OFF should be low for TV on condition, please check Q114’s collector.

  • Page 43: Ci Module Problem

    B. CI MODULE PROBLEM Problem: CI is not working when CI module inserted. Possible causes: Supply, suply control pin, detects pins, mechanical positions of pins.  CI supply should be 5V when CI module inserted. If it is not 5V please check CI_PWR_CTRL, this pin should be low.

  • Page 44: Staying In Stand-By Mode

    C. STAYING IN STAND-BY MODE Problem: Staying in stand-by mode, no other operation. This problem indicates a short on Vcc voltages. Protect pin should be logic high while normal operation. When there is a short circuit protect pin will be logic low. If you detect logic low on protect pin, unplug the TV set and control voltage points with a multimeter to find the shorted voltage to ground.

    E. KEYPAD TOUCHPAD PROBLEMS Problem: Keypad or Touchpad is not working Check keypad supply on MB130. F. USB PROBLEMS Problem: USB is not working or no USB Detection. Check USB Supply, It should be nearly 5V. Also USB Enable should be logic high. USB Control is optional, so U109 and U117 may not be added.

  • Page 46: No Sound Problem

    G. NO SOUND PROBLEM Problem: No audio at main TV speaker outputs. Check supply voltages of 24V_VCC, VDD_AUDIO and 3V3_AMP with a voltage-meter. There may be a problem in headphone connector or headphone detect circuit (when headphone is connected, speakers are automatically muted).

  • Page 47: Standby On/Off Problem

    H. STANDBY ON/OFF PROBLEM Problem: Device cannot boot, TV hangs in standby mode. There may be a problem about power supply. Check main supplies with a voltage-meter. Also there may be a problem about SW. Try to update TV with latest SW. Additionally it is good to check SW printouts via Teraterm program.
