When was the Lamp last replaced,the lamp require changing.

the lamp ballast is bad and needs replacement.

yes, go here for more help. There is a file on how to download codes and clear system.

The number of flashes is giving you a lamp fault code, LFC. What is it giving you?

Diagnostic Test Modes Without Scan Tool
Two mode options are available under the diagnostic test modes:

• user mode.
• diagnosis mode.

The ignition switch is used to alternate from one mode to another.
Diagnosis Mode
The diagnosis mode will display any fault present in the system. The SRS will not enter diagnosis mode if no malfunction is detected.
User Mode to Diagnosis Mode
NOTE: The SRS will not enter diagnosis mode if no fault is detected in user mode.

1. Ignition switch to ON.

1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.

1. Wait more than three seconds.

1. Repeat steps 1 through 3 three times.

1. Ignition switch to ON.

Diagnosis Mode to User Mode — After Repair

1. Ignition switch to OFF for at least one second.

1. Ignition switch to ON.

Diagnosis Mode to User Mode — During Diagnosis
NOTE: If switch from Diagnosis Mode to User Mode is required while diagnosing a fault, carry out the following procedure.

1. Ignition switch to ON.

1. After the air bag warning indicator lights for seven seconds, set ignition switch to OFF within one second.

1. Wait more than three seconds.

1. Repeat steps 1 through 3 three times.

1. Ignition switch to ON.

Clearing Lamp Fault Codes
NOTE: Lamp fault codes must be cleared from memory before proving out the system.
NOTE: When a new RCM is installed, the air bag warning indicator will operate in user mode. Switching to diagnosis mode is not required.
To clear lamp fault codes after a repair, carry out the procedure to switch from diagnosis mode to user mode. Once in the user mode, the lamp fault codes will be cleared from memory.
Lamp Fault Codes
If the air bag diagnostic monitor detects a current fault, the fault code will be displayed with a flashing sequence of the air bag indicator. The fault code consists of:

• A start signal to indicate the beginning of a fault code.
• A number of flashes indicating the particular code that has been set.

The start signal:

• begins with two seconds off.
• two seconds on.
• off.
• one second on.
• two seconds off.

Following the start signal, if any current fault is detected, the fault code will be displayed. The fault code:

• is a series of half second flashes of the air bag indicator.
• is followed by the start signal.

The start signal and the code for any current fault will repeat until the ignition is switched off or the air bag diagnostic monitor is switched to the user mode.
Inspection and Verification

1. Verify the customer concern by checking the air bag indicator in the instrument cluster. Refer to Prove Out in this section.

1. Visually inspect for obvious signs of mechanical and electrical damage using the following chart.

Visual Inspection Chart Mechanical Electrical

• Damaged air bag diagnostic monitor bracket

• Open fuse
• Damaged wiring harness
• Loose or corroded connectors
• Circuitry open or shorted
• Damaged shorting bars

1. If the concern is not visually evident, enter the system Diagnosis Mode.

1. If no DTCs are displayed in the Diagnosis Mode, proceed to the Symptom Chart in this section.

1. If DTCs are retrieved, proceed to the Air Bag Diagnostic Monitor Fault Code Table in this section.

Air Bag Diagnostic Monitor Fault Code Table Code Component/Fault Description 0 Normal Operation/No Fault Detected 1 Front Passenger Safety Belt Pretensioner 2 Driver Air Bag Module Circuit Is Faulted 3 Front Driver Safety Belt Pretensioner 7 Air Bag Diagnostic Monitor Fault 8 Passenger Air Bag Module Circuit Fault 9 Low Battery Voltage

Check the breaker in the panel and the fuses in the disconnect at the outside unit. If that doesn't do it. call a heating and air technician instead of an electrician.

The buzzing is the ballast for the lamp trying to light the bulb. From what you've described it is a lamp failure. It's not that hard to change but you'll have to obtain a new lamp first. You can try and buy it from LG (800-243-0000) but I'm not sure if they'll sell to a consumer. Then you have to reset the lamp timer after you replace it. Hold the mute on the remote and the enter button on the tv at the same time for about 8 seconds and a screen will come up asking if you want to reset the timer. Just follow what it says to reset it.
