Hitachi T’Con board 19-100056 faults – 37 inch Hitachi LCD TVs – input voltage 12V
No display problem
* IC5= BUF12800 Gamma Correction Amplifiers IC. If this IC failure, it will cause the TV has No Display.
* IC6= BD8161 power management IC. If this IC failure, it will cause the TV No Display.
* IC2= TCON102A-F. If this IC failure, it will cause the TV has No Display.
# Sometimes Watermark Display or Rainbow Screen problem too can occur.
Plain white screen problem or No display
* IC4 EEPROM IC. If this IC failure, it will cause either TV has No Display or White Screen.
