SOURCE: LG 50inch Plasma received loud sound then went black

My friend's LG 50" plasma tv has the same problem and it cannot light up. The picture and sound are working fine. But the brightness is too low. It is purchased 2006 too and out of warranty. So I opeend up and found 9 capacitors 3300uF 10V on the power module at the middle of TV are popped. I am planing to replace all of them. They are available at digikey.com. I think this model's power module has design flaw. The cap rating may to low. 10V? Stay tune to see what happen after I change the all the caps.

After connecting the Wii to LG TV (55 inch LD520C) the LG TV will not stay on! it blinks an image 3 times (maybe 10 seconds total), then turns OFF!! we disconnected the Wii, but the LG TV still turn


How old is the TV? LG warranties its TV's for 1 year unless you have a extended warranty from where you got it which is stupid not to have. Was the TV exposed to moisture or bugs? I've never heard of a Wii corrupting a TV. If no warranty then it could be a power supply or the main board. Find a repair service that gives free estimates, find out what needs to be fixed then go online and find the replacement part-Ebay.com and www.shopjimmy.com are good sources for parts. Replacing parts is easy, a screwdriver for screws and unplug cables by hand. If it's a power supply wait 1 hour before removing because the capacitors can still hold a charge and to be safe hold it by the edges of the board and put it on a non conductive surface like glass. If it's the Main board just switch it butsometimes after LG and Samsung main boards are replaced Solarization can happen. If it does just google it and you will find a easy fix. Good Luck

I have Lg 50pc3d-ud and it has very dark spots on the tv that moves around. The screen is also very dark no matter the settings. The dark spots aren't always there, they go away sometimes but if...


This problems ur tv are having only can be two causes 1) The Y-Sustance main tuner logic board or 2)The tv Plasma screen panel itself it is slowly leaking radiaton and dying,if it is the tv plasma screen panel itself it is dying than the tv not worth repairing because by replacing the plasma screen panel itself will cost the same as a new tv itself.The Y-Sustance board-that the tuner main logic board that take in the tv incomming broadcasting signal cable.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish Y-Sustance main tuner logic board for replacement.This tv problems are 50/50 between the Y-Sustance main tuner logic board or the very exspensive plasma screen panel itself.

I heard small pop then lost power while watching my lg 50pg20. No red or blue lights on the power switch. What could be wrong?


you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

My lg tv (had since Nov) says no signal for the tv or dvd player. How do I fix this?


Try unplugging all inputs and the power cord from the TV for 5 minutes. This will allow the main board to reset.
Next, just plug in the power plug to the TV, power up the TV, and even though there is not a source connected to the TV, check at least three inputs and see what the TV will report on the screen for each input.
Next, turn off the TV, plug in all known working devices (Cable/Antenna, DVD, Blu-Ray, Cable/Satellite box, Game, ….) with a known working cables to the TV, make sure all the devices connected to the TV are powered up and on, and now power on the TV.
Now check to see if the TV is seeing valid signal for all the inputs connected to the TV.
If your TV cannot see any signal at any of its inputs (HDMI1, HMDI2, HDMI3, AVI1, AVI2, Component1, ……), then the main board has failed and need to be replaced.
Good Luck.

LG plasma buzzing


Problem is probably with your cable box as you have confirmed that the set is working by using the dvd player, that is unless you have a bad cable for the cable box.
