LED TV Wont Turn on, just shows red indicator light

It indicates that the TV is not receiving enough power to operate normally.

• The power cord or outlet might be faulty or loose. Try plugging the TV into a different outlet or using a different power cord. Make sure the cord is firmly connected to the TV and the outlet.
• The TV might have a blown fuse or capacitor. This would require opening the TV and replacing the damaged component. This is a risky and complicated procedure that should only be done by a qualified technician. Do not attempt to do this yourself unless you have the necessary skills and tools.
• The TV might have a software glitch. Try resetting the TV to its factory settings by following these steps:
  1. Turn off the TV and unplug it from the power source.
  2. Press and hold the power button on the TV for 10 seconds.
  3. Plug the TV back in and turn it on.
  4. If the TV shows a menu, select the option to restore factory settings. If the TV does not show a menu, repeat steps 1-3 until it does.

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.

Re: Bravia KDL46EX720. Red LED blinks 4 times and TV wont turn on. What is the problem?

Do a Power Reset.

1. Turn off the TV.
2. Unplug the power cord of the TV from the electrical outlet.
3. Let the TV remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet. (If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.)
5. Turn on the TV.

If the issue still persists after performing power reset, that may be an indication that the TV needs service. You may refer to this link to locate the nearest Sony authorized service center in your area.

Setup codes to check with Samsung TV are: 0105 0077 0076 0109 0007 0009 0004 0005 0085 0172 0942 0358 0012 0015 0080 0104 0106
Direct Code Entry

1. Press and hold the SETUP button until the red indicator stays on, then release the SETUP button.
2. Press and release the desired Mode button (TV, VCR, etc.). The red indicator blinks, then stays lit.
3. Enter the 4 digit code from the code tables. Note: after a valid code entry, the red indicator turns off. For an invalid code, the red indicator flashes.
4. With your device on, press CHANNEL UP. If the device responds, no further programming is required. Note: If some buttons do not operate your device, try one of the other codes for your brand.

Code Search
If after trying "Direct Code Entry" your device does not respond, or if your brand is not listed, try doing a search of the code library for your code by following these steps.

I had the same problem. all the service reset would only make the display come on for a few second with no "k" on the screen - only the channel would show up. I purchased a complete set of board for the lcd on ebay, and started swapping them one by one. The inverter boards were the culpret. Tele working 100% since that board swap.

Make sure you try every code in the list for your JVC TV.
The codes for your Jumbo Universal Remote to control a JVC television are 013, 054, 055, 060, 065, 067, and 089.

To program your remote by entering a code, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Enter the first set of 3-digit codes from the list. The LED will blink once every keypress. After the 3rd digit, the red LED will turn off indicating that the code was recognized for the device. If the code was not compatible, the LED will flash several times and you need to return to step 2 to try that code again or to try the next code in the list.
   
5. After the LED has turned off, aim the remote at the TV and press ON/OFF. If the device turns off, you have used the correct code and the remote was successfully programed. If the device does not power off, return to step 2 and try again with the next code in the list.
   

To have the remote try each TV code it knows one at a time, follow these steps:

1. Turn on your TV.
2. Press and hold the CODE SEARCH button for at least 3 seconds until the red LED lights up and stays lit.
3. Press the TV button on the remote so that the LED blinks once and then remains solid red.
4. Press the ON/OFF button slowly and repeatedly until the TV turns off. The LED will blink once each time you press the ON/OFF button.
   
5. Once the TV turns off, press the ENTER button to store the code and the LED will turn off.
   

I hope that helps.
