I would have to say that you have bad capacitor in the power supply.Have you taken the TV apart?If you can take it apart,and send some pictures of the board with the power cord going to it,I can tell you which capacitors if any are bad.They have a rounded top to them instead of being flat.Also,how many blinks does the power light blink?Usually it's a series of flashes,and then it repeats.I hope this helps.Thank You very much!

Z50PX2D - I did not have the typical "Popping" Problem, nor have I ever had any Picture Problems. When I try to turn the set on, I hear the normal "Click", and the entire set is dead, standby light turns...

I own the same set. I had the "pop" happen to me. I decided not to fix the set, but before trashing the TV I removed all the boards and parts that I could. This included the Power Supply Board and the Main Board along with the Y Sus, Z Sus, Y Buffers, Speakers, Cooling Fans and few other things I don't know the name of. I'll sell all these parts $150, cheaper than you will find the Power Supply Board by itself. With all these parts you can fix the set cheaply no matter what ends up being the problem. Let me know if you are interested.

My zenith plasma tv popped real loudlike a car backfiring and then the tv picture went black. power on green light wil turn on but it automatically cuts itself back off to the red light

There's an over current fault in the power supply or the Y-sustain convergence board. The loud pop was either a capacitor or pico-fuse breaking from excessive current overload. Sounds like 2 or 3 mosfets have shorted at the gate ends. Plasma TV's always have this problem because they generate too much heat and the components cant take the load conditions. Make your next TV an LCD...

To fix this problem have your local repair shop do it for you.....

any questions please ask.....

Loud Pop and no more picture-Z50PX2D

One hour ago, Zenith z50px2d gave out a loud POP. Actually, more of a CRACK, like a stone hitting your windshield - startled the heck out of me. . (Was watching SyFy movie - space ship going through a meteor shower - my wife thought it was part of the show) at first, just dark picture, now its nearly dead: when i press power, the green power light flashes four times and turns red, off. Tried unplugging, same thing. I don't have a solution right now, just wanted to add to the body of evidence. I do have the equipment at home and will be taking it apart and share any insights I get.

My Zenith 50 in. tv won't come on, it went out yesterday. When you push the the power button, it flashes green for a few seconds then goes to the red off button.

it's your power supply that has gone. I had the same problem after owning my LG Z50PX2D for 2 months. The repair shop had it for 6 months. now I have the famous "POP & BLACK SCREEN SICKNESS" LG/Zenith should fix this.

ViewSonic Va 912B no power light, no display

Your power suplly is blown you can repair if you know alittle about repair can use a soldoring iron. You have to take the back apart and look at power supply. Look for blown caps they show raised tops bubbling on top. If you can't repair I do repair of monitor for the schools where I live if you don't want to try and repair it cantact me I will pay for shipping for parts.
Good Luck.

Green light blinking- no picture

This just happened to my Z50 yesterday...10 days after it came back from the repair shop! The first repair was for the "popping" problem where the tv makes a loud pop and the screen goes black. This took 6 weeks to get fixed. For this new problem the repair center is getting hold of LG to find out what to do. I am also calling them because I see this is a major problem that people have been experiencing out of warranty. The first customer service rep told me I was out of luck but I am not accepting that answer. Good luck, we'll both need it.
