    Sometimes this happens upwards of 100 times. Unplugging and plugging doesn't do anything. Nor does pressing any buttons.

    Having exact same problem with 50inch LG

  • Anonymous Feb 21, 2009

    I have the LG 50PC1DRA and have the same problem today.

  • whitehouse25 Mar 15, 2009

    We have a 50PC1DRA. When turning on, the green light blinks several times, then goes solid briefly; the picture will flash on briefly then turn off will a audible pop. Power light goes back to red.



    Previously, after several repeats of above, the picture would finally stay on. Now it won't. Please help !

SOURCE: 50 in LG turns on and then clicks and turns back off

The power supply is going in to protect mode. Most often this is a power supply failure, or a failure on one of the circuit boards that is causing the power supply to go in to protect.

If the power supply fault is not too complicated an experienced tech may be able to service it without changing the compete circuit board.

The tech will service this by substituting boards to determine where the failure is occuring. Then he will change the board to fix the fault.

Open the back cover and check the fuse on YSUS Board. If the fuse was gone, replace the YSUS board or ZSUS board.

call 877-543-8325 this is an LG Executive call center and they will fix this for free. I have a 50" plasma I bought january 2006 which is out of warranty by 5 months. They faxed me and the LG repair shop a 30 day warranty for my tv to cover the repair. Just tell them you heard a pop and in my case the picture is distorted. All they need is the model number and serial number and they should take care of it. No arguing needed.

Is the system set to the correct input source?
Was anything done to the setup before this started happening.

My Zenith plasma TV blinks green 4 times then goes red, No picture. None of the Capasitors are blown.


I had AWFUL customer service. (Sherry is DREADFUL her # is 1-877-543-8325 she is in"executive services". Ask to speak to her directly...if you would like ZERO help.)

They WILL NOT extend the warranty, even though they know there is a defect with this AND other models. Zenith name on the front...LG guts in the inside.
Ours turns on, screen black and then clicks three times and then turns back off.

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

What is model number and do you have a warranty?

Hi, I've had that happen with TVs before, it tends to be caused by blown capacitors on the motherboard. It can be fixed however it's not something you could easily do on your own, you'd want to take the TV to a local repair shop, I've seen the repair range from $50 up to $250 or so in my experience.
