Need code for Directv remote for 26LG Flat Screen TV

Program TV Code
1. Turn on the TV.
2. Locate the 5-digit code for your TV.
3. Slide the MODE switch to the TV position.
4. Press and hold the MUTE and SELECT keys at the same time until the green light under the TV position flashes twice, then release both keys.
5. Using the number keys enter the 5-digit code for your brand of TV. If performed correctly, the green light under TV flashed twice.
6. Aim the remote at your TV and press the PWR key once. Your TV should turn off. If it does not turn off, repeat steps 3 and 4, trying each code for your brand until you find the correct code.
7. Slide the MODE switch to the DIRECTV position. Press TV POWER. Your TV should turn on.

Program DVD, VCR, Stereo Receiver, and Stereo Amplifier Code
The AV1 and AV2 switch positions can be setup to control a VCR, DVD, STEREO, second DIRECTV Receiver or second
1. Turn on the component you wish to control (e.g. your DVD Player).
2. Locate the 5-digit code for your component.
3. Slide the MODE switch to the AV1 (or AV2) position.
4. Press and hold the MUTE and SELECT keys at the same time until the green light under AV1 (or AV2) flashes twice, then release both keys.
5. Using the NUMBER keys, enter the 5-digit code for the brand of component being set up. If performed correctly, the green light under the selected position flashes twice.
6. Aim the remote at your component and press the PWR key once. The component should turn off; if it does not, repeat steps 3 and 4, trying each code for your brand until you find the correct code.
7. Repeat steps 1 through 6 to set up a new component under AV2 (or AV1).

Unable to Find Correct Code
If you were unable to find the code for your brand of TV or component, you can try a code search. This process may take up to 30 minutes.
1. Turn on the TV or component. Insert a tape or disk if applicable.
2. Slide the MODE switch to the TV, AV1 or AV2 position, as desired.
3. Press and hold the MUTE and SELECT keys at the same time until the green light under the selected switch position flashes twice, then release both keys.
4. Enter 9-9-1 followed by one of the following four digits:
Satellite - 0
TV - 1
VCR/DVD - 2
Stereo Receiver/Stereo Amplifier - 3
5. Press PWR, or other functions (e.g. PLAY for VCR) you want to use.
6. Point the remote at the TV or component and press CHAN+. Repeatedly press CHAN+ until the TV or component turns off.
NOTE: Every time CHAN+ is pressed the remote advances to the next code and power is transmitted to the component.
7. Use the CHAN- key to step back a code.
8. When the TV or component turns off, stop pressing the CHAN+ key. Then, press and release the SELECT key.
NOTE: If the light flashes 3 times before the TV or component responds, you've cycled through all codes and the code you need is not available. You must use the remote that came with your TV or component.

Verifying the Codes
Once you have set up the DIRECTV Universal Remote Control using the above steps, use the following instructions to find out the 5-digit code to which your component responded:
1. Slide the MODE switch to the appropriate position.
2. Press and hold the MUTE and SELECT keys at the same time until the green light under the selected switch position flashes twice, then release both keys.
3. Enter 9-9-0. (The green light under the selected switch position flashes twice.)
4. To view the first digit in the code, Press and release then number 1 key. Wait three seconds, and count the number of times the green light flashes. Write this number down.
5. Repeat step 4 four more times for the remaining digits; i.e., press number 2 for the second digit, 3 for the third digit, 4 for the fourth digit and 5 for the final digit.

Depending on how you set up your remote, the VOL and MUTE may control the volume only on your TV, regardless of the position of the MODE switch. This remote can be set up so that the VOL and MUTE keys work only with the component selected by the MODE switch. To enable this feature, perform the following steps:
1. Press and hold the MUTE and SELECT keys until the green light under the DIRECTV position flashes twice, then release both keys.
2. Using the number keys, enter 9-9-3. (The green light will flash twice after the 3.)
3. Press and release the VOL+ key. (The green light flashes 4 times.)
Now the VOL and MUTE keys will work only for the component selected by the MODE switch position.

To Lock Volume to AV1, AV2 or TV
1. Slide the MODE switch to the AV1, AV2 or TV position to lock the volume.
2. Press and hold the MUTE and SELECT keys until the green light under the selected switch flashes twice and release both keys.
3. Using the number keys, enter 9-9-3. (The green light flashes twice.)
4. Press and release the SELECT key. (The green light flashes twice.)
