LG 50PX5D, I heard a loud pop and the screen went

buy a new one sounds like its gone forever ?

Loud pop is usually damage to one of the boards that drive the screen--inverters or T-con type boards.

Not likely to be a do it yourself repair.

you have a blown cap in your lg's power board the electoletic cap looks like a can and the bad one will have a domed top where it vented the value is written on the side you can replace them or have it done and you should be good to go

Ur tv have burns capacitors,look for pop ups caps.

Replace the y-sus board located on the right after removing the back panel.

check inverter. adjust brightness and contrast.

Sounds like the Power supply module. I would take it in to service center ASAP!

Plasma tv's don't last long....buy a led tv.

yes that was from that cut power you should go now to the authorized service to fix that problem

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.
