Machine Disassembly and Replacement

General Information

This chapter contains step-by-step procedures on how to disassemble the AT1935 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.
