Check the area of your repair for unsoldered or poorly soldered Earth Ground connections. Check the entire board surface for solder splashes and bridges. Fig. A. Using an AC voltmeter to check AC leakage. 2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors. 3. Check that all control knobs, shields, covers, ground straps, and mounting hardware have been replaced. Be absolutely certain WARNING!! that you have replaced all the insulators. 4.

The boards are identified by the LF logo located close to the board designation e.g. H1 etc [ see example ]. The servicing of these boards requires special precautions to be taken as outlined below. It is strongly recommended to use Lead Free Solder material in order to guarantee optimal quality of new solder joints. Lead Free Solder is available under the following part numbers : Part number Diameter Remarks 7-m 640-005-19 0K .3m 0.25g 7m -640-005-20 0K .4 m 0.50g m 7m -640-005-21 0K .5 0.50g 7m -640-005-22 0K .6 m 0.25g 7m -640-005-23 0K .8 m 1.00g 7m -640-005-24 1K .0 m 1.00g 7m -640-005-25 1K .2 m 1.00g 7m -640-005-26 1K .6 m 1.00g Due to the higher melting point of Lead Free Solder the soldering iron tip temperature needs to be set to 370 degrees centigrade. This requires soldering equipment capable of accurate temperature control coupled with a good heat recovery characteristics.

If an error occurs, the POWER LED will automatically begin to flash. The number of times the LED flashes translates to a probable source of the problem. A definition of the POWER LED flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom is difficult to reproduced use the Remote Commander to display the record that is stored at the internal NVM to specify the cause of the failure. Diagnostic Test Indicators When an error occurs, the POWER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, the LED will identify the first of the problem areas. If the errors occur simultaneously, the one that corresponds to the fewest flashes is identified first. Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “0”.
