Plasma TV Chassis F89A Model Code PS64D8090FSXZG SERVICE MANUAL Plasma TV PS64D8090FS Refer to the service manual in the GSPN (see the rear cover) for more information. 1. Precaution 1. Precaution To avoid possible damage, electric shocks or exposure to radiation, follow the instructions below with regard to safety, installation, service and ESD. 1.1. Safety Precautions 1) Make sure all protective devices are properly installed including non-metallic handles and compartment covers when installing or re-installing the chassis or chassis assemblies. 2) Make sure that no gaps exist between the cabinets for children to insert their fingers in to prevent children from receiving electric shocks. Gaps mentioned above include ventilation holes of a too great magnitude between the PDP module and the cabinet mask, and the improper installation of the rear cabinet. Errors may occur when the resistance is below 1.0M or over 5.2M. In these cases, make sure that the device is repaired before sending it back to the customer. 3) Check for Electricity Leakage (AC Leakage Test) WARNING Do not use an insulated transformer for checking the leakage. Use only those current leakage testers or mirroring systems that comply with ANSIC 101.1 and the Underwriter Laboratory's specifications (UL1410, 59.7).

When voltage exceeds the specified limits, check each special part. 5) Warning for Engineering Changes: Never make any changes or additions to the circuit design or the internal part for this product. Ex: Do not add any audio or video accessory connectors. This might cause physical damage. Furthermore, any changes or additions to the original design/engineering will invalidate the warranty. 6) Warning - Hot Chassis: Some TV chassis are directly connected to one end of the AC power cord for electrical reasons. Without insulated transformers, the product can only be repaired safely when the chassis is connected to the earthed end of the AC power source. To
