  • Page 81 3. Tips Of Some Typical Troubleshooting White screen First check voltage in HI-voltage Board; otherwise check the voltage of MAIN board , if abnormal , the problem occurs in 1U1or 1U2. If the voltage is OK, check the LVDS. At last the connection between the main board and drive board may be the target for troubleshooting.
