GENERATES UNUSUAL PATTERN OF DATA 'COF' IC UNIT.
GENERATES UNUSUAL PATTERN OF DATA 'COF' IC UNIT.
- In case of generating unusual pattern of Data COF IC unit as picture given below, there is problem in the check that is input to Data COF IC.
- In case of (case1,2,3): Confirm the connection of Data COF connector. Replace the relevant X B/D.
- In case of (case 4&5): Confirm the connector that is connected from CTRL to X B/D. Replace the relevant X B/D or CTRL B/D.
- REGULAR STRIPE IS GENERATED ABOUT THE QUANTITY OF ONE DATA 'COF' IC OR MORE
- In case of generating regular stripe about the quantity of the Data COF IC, there is problem at the output of the output flatworm of X B/D. In case of generating regular stripe about the quantity of two Data COF IC, that means the data which is conveyed from CTRL B/D doesn't conveyed well.
- Confirm the XB/D connection connector plugged in well - correspond to unusual screen.
- Replace relevant XB/D or CTRL B/D.
SCREEN DISPLAY FORM
THE SCREEN DISPLAY HAS A PROBLEM FOR SCAN FFC.
- It bay be a problem between Scan FFC and Y B/D.
- Check the connection of Y B/D and Scan COF.
- If the Scan IC is failed, replace Y DRV B/D.
SCREEN DISPLAY FORM
Check a method or SCAN IC.
THE SCREEN HAS VERTICAL LINE WITH REGULAR GAP. A VERTICAL STRIPE FLASH AT ESPECIAL COLOR.
- This is a problem about control B/D.
- Replace Control B/D.
SCREEN DISPLAY FORM
A DATA COPY IS HAPPENED INTO VERTICAL DIRECTION
- In this case, it's due to incorrect marking of the scan wave.
- Replace a Y DRV B/D or a Y SUS B/D
