SERVICE PRECAUTIONS 1.1 SERVICE PRECAUTIONS 1) You should conform to the regulations governing the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual. 2) Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction. 3) Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during power-on mode may damage the ICs inside the unit. 4) To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder) by referring to "the DISASSEMBLY" . 5) After replacing the pickup unit, be sure to skew adjustment. 6) During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged. 7) In case the internal fuse blows out, check the latter part of voltage. 8) Touch panel consists of the glass. Take good care for its handling. Dropping the panel or adding severe impact on it may cause the risk of cracking. Also, the end face of glass is not chamfered. Use gloves and the like to protect your fingers from being cut. 9) In case the internal fuse blows out, check the latter part of voltage. 10) Hot areas White area: Hot area.

Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden). The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com AVH-P4000DVD/XN/UC 8 1 2 3 4 1 2 3 4 C D F A B E 2.
