Overview

This document outlines a service hint for Panasonic Plasma TVs, specifically models TX-P60ZT60E and TX-P60ZT65B, addressing a common issue of micro cracks appearing near the edge of the panel after the back cover has been removed and re-fitted. The primary function of this document is to provide authorized service agents with a detailed guide on how to properly re-assemble the back cover to prevent panel damage.

The core problem described is the appearance of micro cracks, bubbles, and/or thin jagged lines near the edges of the panel, which typically manifest after the back cover has been removed and subsequently re-fitted. This issue is directly attributed to incorrect re-fitting of the back cover. The document emphasizes the critical importance of proper back cover assembly to avoid permanent damage to the PDP (Plasma Display Panel).

For usage, the document provides a clear warning: "DO NOT move, transport, carry or perform any type of handling of the TV without the back cover." This highlights the fragility of the PDP panel when the back cover, which provides structural integrity and protection, is not securely in place. The recommended method for preventing damage is to "Make sure the back cover is properly assembled when handling the TV to avoid permanent damage to the PDP panel." This instruction is crucial for all repairs that necessitate the removal and re-assembly of the back cover.

The document includes detailed visual aids and descriptions to guide service agents through the correct assembly process. It breaks down the back cover assembly into three main sections: Top, Bottom, and Side. For each section, it illustrates both "OK assembly" (correct) and "NG assembly" (incorrect) scenarios, providing clear visual distinctions.

In the "OK assembly" scenario for the Top Section, the back cover must be aligned with the aluminum metal bezel groove. The visual representation shows the back cover fitting snugly inside the bezel. Conversely, the "NG assembly" for the Top Section depicts the back cover not aligned properly, protruding outside the aluminum metal bezel groove, indicating an incorrect fit.

Similarly, for the Bottom Section, the "OK assembly" requires the back cover to be aligned with the aluminum metal bezel groove, ensuring a flush fit. The "NG assembly" for this section shows the back cover misaligned and extending beyond the bezel groove.

The Side Section also follows this pattern, with "OK assembly" demonstrating the back cover correctly aligned within the aluminum metal bezel groove, and "NG assembly" illustrating it misaligned and outside the groove.

A key maintenance feature highlighted is the instruction to "Make sure back cover is correctly assembled / aligned before inserting screws." This step is critical because attempting to insert screws when the back cover is not properly seated can force the panel into an incorrect position, leading to damage. The document explicitly warns: "DO NOT insert screws if the back cover is not correctly assembled / aligned as this may cause damage to panel." This preventive measure is vital for avoiding irreversible damage during the re-assembly process.

The document also provides general notes that are essential for proper maintenance and repair:

Screw Insertion: Reiteration of the warning not to insert screws if the back cover is not properly aligned, directing the user to refer to the detailed sections for proper alignment. This underscores the importance of visual inspection and correct positioning before securing the cover.
Material Specification: An instruction not to use material that is out of specification. This ensures that only appropriate and compatible components are used during repairs, maintaining the integrity and performance of the device. Using incorrect materials could lead to further issues or compromise the structural stability of the back cover and panel.
Back Cover Perimeter: A directive to "Make sure the back cover perimeter has no deformations, as this may result in bad assembly and possible panel damage." This emphasizes the need to inspect the back cover itself for any physical damage or warping before re-assembly. A deformed back cover will not fit correctly, regardless of the technician's efforts, and will inevitably lead to misalignment and potential panel damage.

The overall function of this service hint is to standardize the back cover re-assembly process for these specific Panasonic Plasma TV models, thereby reducing instances of panel damage caused by improper handling and assembly. It serves as a practical guide for service agents, combining clear instructions with illustrative examples to ensure that maintenance procedures are performed correctly and safely. The emphasis on visual inspection, correct alignment, and the use of appropriate materials are central to the successful and damage-free servicing of these televisions.
