This is an indication of error codes for defects inside the TV. In order to ensure this is not caused by some erratic signal to system IC, switch off TV manually, Switch off power and remove plug and wait for 48 hours and retry. If it does not work even then, the TV might need service.

Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

The red flashing light is the service code. My guess is the power supply is bad now, but it could be something else. If the TV is under warranty, take it in and get if fixed. If it is not, then you may try to check the power supply first. Count the flashes of the red light and check online for the issues when this model flashes, 4 times or 6 times... or 9 times, etc.

Good luck!

27 mgz oscillator on the back of the main board. Try resoldering it, or replace it.

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.

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.
