SOURCE: LG 50PC3D PLASMA WILL NOT TURN ON

Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you save $300 least!

LG 50PC5D-UL plasma tv not getting a picture.
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

LG 42PC!R Plasma TV turns on and then green led blinking with no ppicture and sound !
Your problem is most likely a fried circuit board. I always connect my good electronic to a back up battery. but your problem might have been storm or surge related, I would take it to a repair center and get an estimate.

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.

3 months ago Led blinks 7 times now Led blinks 6 times
Sorry to hear that. You could fix it with Best Buy or the warranty service repairman recommended by Panasonic.com
I have a client that had used one of the panasonic repairman to fix the same problem that you have about a year ago,the TV is good ever seen.
I am in the A/V installation business, my recommendation(Pioneer Kuro Plasma TV or Sharp LCD.)Very good track records from my clients.

Philips 42PF7320A blinks 3 times every time i hit the power button
The SSB is small self contained board that u connect your Antenna, and HDMI to. An error three is a communication error between the SSB and to Logic board ( located underneath the SSB on the back fo the plasma panel that is just below the power supply. U can check parts.com and see if u want to purchase a SSB for this TV. Is the 3blinking lights coming from the front of the TV. Also check the power supply and see how many times the green led blinks on the upper left of the power supply and let me know.
