I have an LG model 50PC1DR that is approximately 2 yers old. when i try to turn it on, i can hear it "hum" momentarily as the light flashes like it's trying to turn on. i can see just for a second on the screen "connecting to cable box" (which it's always done), then there's a "pop" and it turns off. it started this about a month ago, and now i cannot get it to come on at all. What a product...

I'm having exactly same problem. Not only I also other people have same issue. I dropped this heavy TV to the certified LG repair centre and the esimation cost for repair is $500.00 CDN. We decided to pick it up without the repair even we paid $100.00 just for the inspection.

My TV was working but no power at all now.
The repair centre says it's defact part so they are not responsible.
LG should recall this model.

I had this same problem it is your capacitors on the power supply board you have to replace nine of them they are the ones that are all the same size i fixed it myself repair shop wanted $500 it only cost $30 to do it my self u just need to kno how to solder wich i didnt kno how to do but i managed to do it u just cant let any solder to connect to anything its worth the try cause if u mess up u can always jus buy another board

I have a 50pc1dr and it just makes a click when I try to turn it on?I took off the back and no capacitors that look bad.The repair man said it was the power supply but thats the last thing I want to do.If there is any body who has an idea please let me know.Thankx
