Machine Disassembly and Replacement

General Information

This chapter contains step-by-step procedures on how to disassemble the AT2635B series for

maintenance and troubleshooting. To disassemble the TV, you need the following tools:

Wrist grounding strap and conductive mat for preventing electrostatic discharge

Small Philips screwdriver

Philips screwdriver

Hexagonal screwdriver

Tweezers

Note:

The screws for the different components vary in size. During the disassembly process, please group

the screws with the corresponding components to avoid mismatch when doing assembly. When you

remove the boards, please be careful not to scrape them.

Warning!

The module is drived by high voltage. If you need to handle the module during operation or just after

powered off, you must take proper precautions against electric shock and must not touch the drive

circuit portion and metallic part of module within 10 minutes. The capacitors in the drive circuit portion

remain temporarily charged even after the unit is powered off. If the residual voltage is strong enough,

it could result in electric shock. Thus, we strongly suggest that you put on the wrist ground strap and

put the component on the conductive mat or bag. Besides, please keep the unit grounded during the

whole process of disassembly and assembly.

Before You Begin

Before you proceed with the disassembly procedure, make sure that you do the following steps:

Turn off the power to the TV and all peripherals.

Unplug the AC adaptor and all power and signal cables from the TV.
