When you say that you have replaced the main board i assume you mean the power board? If the green light comes on and blinks when the remote is touched it was never a issue with the mainboard, if it was you wouldnt have any signs of power. In most lcd tvs you have the main board which is normally the power board, the signal board which recieves signal and hold settings of the tv which can be all in one, the other is the inverter board, which scrambles the signal to what you see on the screen, and next we have the back light which lights the screen so you can see the picture, sometimes in certain models as i have learned you can have power/inverter boards which means the inverter and power are all on the same board, in your case i pressume the inverter board is seperate board and probably the issue you need to address, you can buy these online probably the same place you got your new mainboard from. Hope this helps pls post bach what happens.

Lg 47lc7df tv blinks green light, no picture or sound


Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

I can,t program my universal control,how i program it?


Hi,

Configuring codes:

  1. Turn on the component that you want to set up.
  2. Hold the component key down until the green indicator light comes on. The green light should come on after approximately 3 seconds.
  3. Release the component key.
  4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
  5. Within thirty seconds, enter in a 4-digit code number. The component key lights will blink with an upward motion when a code has been successfully entered. In this case proceed to step #5. If the code has not been successfully entered, the componment lights will not blink. In this case return to strep #1 and start over.
  6. Test code by pressing "Power" key. If the component turns off, you've got the right code. Follow the same instructions to set up your other components. If the component doesn't turn off, return to step 2 and use the next 4-digit code listed.

Note: If none of the codes turn your component off, try the Auto Code Scan function.


Auto Code Scan:

The Auto Code Scan feature allows you to set up your components without having to enter in code numbers. The Jensen will do the work for you! (It may take a few minutes to find your code using this method.)

  1. Turn on the component that you want to set up.
  2. Hold the component key down until the light comes on. The green light should come on after approximately 3 seconds.
  3. Release the component key.
  4. If you are programming the DVD or CD device press the "action" key. The red indicator light will come on.
  5. Press "0" - "9" The green light will blink as codes are sent.
  6. As soon as the remote turns your component off, press the "action" key. (You have 1 second in which to press the "action" key to save the code.) The component key lights will blink with an upward motion when a code has been successfully entered. The component is now programmed. To find that code, proceed to Code Readback.
  7. If none of the codes turn your component off, return to step 2 and start over. Thank You

LG 47LC7DF Green Light Blinks 16 Times - No Picture or Sound


Well dont keep it on!

By running it after it shutdown and it finally did its last pop that added another $XX to the parts bill.

The control boards (2) have now failed There are burned Capacitors ( pop!) and possibly even a few transistors burned out. This is not a DIY it is a Tech job as once changed these boards require additional tuning of the convergence factor.
