LG TV struck by lightning - Dennis on June 13th, 2018

A LG 42" TV was struck by lightning and was unresponsive. I first tried replacing the power board but that did not work. Then I bought another main board, put it in and like magic the TV is working fine!

Wicked easy - Katie on May 2nd, 2018

Flashlight test confirmed a backlight issue on my TV. Watched the fix video through a couple of times, then spent an evening doing TV surgery installing the new LED strips. TV fully functional again and for way less than the price of a new one!

Replacing LEDs - Shannon on April 12th, 2018

Google and Youtube led me to ShopJimmy! I've had my LG tv for a little over 2 years when the picture went out. It took the better part of a day but I followed the repair videos and my tv is back and running. Advice: reset picture settings!

Like New - Sam on February 22nd, 2018

Tv would turn on but could only see the display with a flashlight shinning on the screen. Looked up the problem for the model, and found that the LED backlights could be the issue. Found a tutorial by this company to fix it and the parts. Works perfectly.

No previous experience? No problem! - Tom on December 14th, 2017

I simply google the symptoms, and eventually found a YouTube of replacing this part from Shop Jimmy. It looked doable enough, so I invested in the parts and a screwdriver set ($7 more). It took me just over an hour, and the results were the exact same.

LG 42LN5400-UA - Mike on December 5th, 2017

A friend gave me a 42" LG tv with the classic symptoms of no backlights. Turning on the set and selecting menu and then shining a flashlight at the screen showed a faint image of the menu. Replacing all the led strips resolved the problem.

LG TV power supply - Robert on March 23rd, 2015

Set would not come on without first unplugging for at least 30 minutes. Website said there was a 85% chance it was a capacitor on the power supply board. Replaced power supply board. (Very easy). TV working perfectly.

Power Loss - Marc on January 14th, 2015
