PT3-H AVC3-U SAFETY PRECAUTIONS NOTICE: Comply with all cautions and safety-related notes located on or inside the cover case and on the chassis or plasma module. WARNING: Since the chassis of the AVC unit and Plasma Panel unit is connected to both sides of the AC power supply during operation, whenever the receiver is plugged in, service should not be attempted by anyone unfamiliar with the precautions necessary when working on this type of receiver.
PT3-H AVC3-U PRODUCT SAFETY NOTICE Many electrical and mechanical parts in HITACHI television receivers have special safety-related characteristics. These are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual.
PT3-H AVC3-U SERVICING PRECAUTIONS CAUTION: Before servicing instruments covered by this service data and its supplements and addenda, read and follow the “Important Safety Instructions” on page 3 of this publication. NOTE: If unforeseen circumstances create conflict between the following servicing precautions and any of the safety precautions on page 3 of this publication, always follow the safety precautions. Remember: Safety First.
PT3-H AVC3-U General Soldering Guidelines 1. Use a grounded-tip, low-wattage soldering iron and appropriate tip size and shape that will maintain tip temperature within the range 500°F to 600°F. Removal 1. Desolder and straighten each IC lead in one operation by gently prying up on the lead with the soldering iron tip as the solder melts. 2. Use an appropriate gauge of resin-core solder composed of 60 parts tin/40 parts lead. 2.
PT3-H AVC3-U At Other Connections Use the following technique to repair defective copper pattern at connections other than IC Pins. This technique involves the installation of a jumper wire on the component side of the circuit board. Fuses and Conventional Resistor Removal/Replacement 1. Clip each fuse or resistor lead at top of circuit board hollow stake. 2. Securely crimp leads of replacement component around stake 1/8 inch from top. 3. Solder the connections.
PT3-H AVC3-U NOTE: These components are affixed with glue. Be careful not to break or damage any foil under the component or at the pins of the ICs when removing. Usually applying heat to the component for a short time while twisting with tweezers will break the component loose. Leadless Chip Components (surface mount) How to Replace Flat-lC —Required Tools— Chip components must be replaced with identical chips due to critical foil track spacing.
PT3-H AVC3-U AGENCY REGULATORY INFORMATION Federal Communications Commission Notice This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
PT3-H AVC3-U ACKNOWLEDGMENTS AND TRADEMARKS This Plasma Television complies with VESA DDC2B specifications, Plug & Play is a system with computer, peripherals (including monitors) and operating system. It works when the monitor is connected to a DDC ready computer that is running an operating system software that is capable for the plug & play. When a Plug and Play PC is powered on, it sends a command to the Monitor requesting identification.
PT3-H AVC3-U INTRODUCTION The 50HDT50 and 50HDT55 are a Plasma Television set; They are constituted by the combination of two main parts, an AUDIO VIDEO CONTROL Center, and the Plasma Display monitor.

PT3-H AVC3-U BASIC SETUP & OPERATION VIEWING The major benefit of the HITACHI Plasma Television is its large viewing screen. To see this large screen at its best, test various locations in the room to find the optimum spot for viewing. The best picture is seen by sitting directly in front of the TV and about 8 to 18 feet from the screen. During daylight hours, reflections from outside light may appear on the screen.
PT3-H AVC3-U To take measures to prevent the Plasma Display from tipping over and prevent possible injury it is important to mount the unit in a stable place. Securing to a table-top 1. Using wood screws (two) fasten the set to the clamping screw holes on the rear of the Plasma Display stand as shown below. 2. Using commercially available wood screws, secure the set firmly in position. Wood screw two places Securing to a wall 1.
