June 22, 2009 Re: Notice of Repair method Dear Sir/ Madam: LG Electronics has developed a new repair method for reducing PDP mal-discharge symptoms. The new

method allows you to download the Control Board ROM software to correct PDP mal-discharge symptoms not

eliminated by alignment, instead of replacing the PDP panel.

If you encounter this type of situation, please request the Control Board ROM Download Jig by email. Please send

all requests to [email protected]. Your request must include the following information:

1. Service Center Name

2. Account Number

3. Contact Name

4. Mailing Address

Please view the video prior to attempting the repair to ensure you fully understand how to perform

the software download using the jig. Download the zipped file and then follow the download guide. All

software is included in the zip file.

When completing the warranty claim it is very important that you use the defect code “SCDS” for all

Control Board ROM software download cases.

Thank you for your support in this matter and we appreciate the service you have performed for

LG Electronics.

Sincerely,

Tracey Janey, Director

Plasma Control board ROM Update

EXPLANATION:EXPLANATION:

Occasionally a set is encountered that has Mal-discharge (see the next two images on the next two pages). When this type of issue is encountered it is of the utmost importance that all adjustments be checked and corrected. It is possible that this will resolve the condition. If however, after adjusting all adjustments correctly and according to the specific Panel’s voltage label the problem still exist, then it is necessary to upgrade the Control’s boards ROM software.

This document explains the procedure for the Control’s boards ROM software upgrade.

Preliminary SetPreliminary Set--Up Precautions: Perform Normal Panel Alignment first:Up Precautions: Perform Normal Panel Alignment first:

VERY IMPORTANT:

Before beginning with the Control board ROM upgrade, it is of the utmost importance that ALL Panel Adjustments be accurately set in accordance to the Panel’s Label.

Failure to do so will negate the added benefits of performing this upgrade to the software.
