Resumen del manual
The negative pole of tantalum capacitors is highly susceptible to heat, so use special care when replacing them and check the operation afterwards. 6. Cautions in handling flexible PCB Before working with a soldering iron, make sure that the iron tip temperature is around 270... Take care not to apply the iron tip repeatedly(more than three times) to the same patterns. Also take care not to apply the tip with force. 7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. - 2 - EXPLODED VEIW - 3 - 4*.
