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

Had my LG for 2 yrs now and a few weeks ago the picture would pop and then go black - alslo no sound. I couldn't change inputs - nothing. Can't see anything on the screen or hear sound but the power is on. For fear that it wouldn't turn back on, I would never power it off. I just changed the input. Left the tv on for 2 weeks and it did it's final pop and there is absolutely no picture or sound. I've un-plugged it for several days, tried turning it off and on and plugging cable in directly to tv instead of through DVR box. It seems like a part is bad. The power is only (green light blinks 16 times to turn on) however no picture or sound - just a black screen. Any suggestions?

    The tv is 2 yrs old! I have old tube TV's that are older than I am (30) that still work! To pay $1500 and have a tv work for 2 yrs and break is fricken ridiculous!

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.

    Yes i Understand I have a sanyo 62" that is 35 years old and is still a lovely TV with lots of bells and whistles not on modern TV's
    We live in a throw away society now and things are not meant to last, its all about turnover, the $ and of course greed.

    Many of the Boxy old TV's will work forever almost even into full digital with a set top box and outive tv's that are rolling off the assembly lines in Korea and China today.

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

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.

Lg tv no sound or picture, blinking green light but back light on

The common problem is the main board, instead to purchase a expensive main board, you may try to re-flow the soldering on the main board, it is the only way you may fix the main board at your home.
Re-Flow Soldering Procedure for LG Main Board

    1.Pre-heat your kitchen oven to 385 degree (No more than 400 degree);

    2.Put the main board on a card board (like a pizza box board) in the oven;

    3.Heat it for 10 minutes (No more than 10 minutes);

    4.Turn the oven off & leave the door open, at this moment, do not touch or move the board until it colds down to the room temperature.

    5.Install the board in the TV & try it out.

47LC7DF, Green light comes on, blinks with remote

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 42 LCD no sound or picture

Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
