FCO E009 Work Instructions RGB levels are too low to drive some monitors. Also sync on green is no longer required. This modification need only be carried out at the requested of the customer. However, it may be performed at the same time as FCO E008, and it is recommended that if the board is being reworked for FCO E008 it is reworked for FCO E009 at the same time. There are two methods, the first being suitable for those with vacuum desoldering equipment. The second is suitable for those without this equipment, to prevent damage to the circuit board. Method 1 Remove the circuit board from the main unit. Desolder resistors R39, R20, R41 and R59, and remove them from the main circuit board. Fit 3x 43.2W 1% 0.25w resistors to R20,41 and 59, leaving R39 empty. If 43.2W resistors are not available, 43W 1% 0.25w may be used as an alternative. These are available from Farnell, part number MRS2543R or RS, part number 148-168. Method 2 Remove the circuit board from the main unit. Cut the leads to resistors R39, R20, R41 and R59, leaving enough of the lead on the board to allow new resistor leads to be soldered to the existing leads except on R39. The leads on R39 may be cut right back to the circuit board. Fit 43.2W or 43W resistor to position R20, R41 and R59, by soldering the resistor leads to old leads. The new leads should be cropped close to the resistor, but allowing this new solder join to be effected. Replace the circuit board in the computer and test the computer thoroughly.
