Screen-blurred Solution

1.Check main board clock output

2. Check whether there is Rosin joint, short circuit or wrong values on resistor or capacitor from main board R\G\B signal inputto main chip;

3. Check whether there is Short Circuit or Rosin Joint between Main board and Connectors (especially between Chip Pins/IC foot resistance/double row pin, flat socket should be pay more attention to.)

4. Change the Screen when necessary
