I have a LG 47ln5700 smart tv. The screen goes black but the sound still works. I replaced the LED strips and the tv worked for about 4 hours and then the same thing happened. Any suggestions?


Bad power supply board can burn out those led strips. Recommend replacing both board and strips at same time. Lg 47LN5700 UH TV Parts

LG model 47LN5700-UH LED TV. There is a single thin vertical line on the screen. I have changed the LED/Power Supply board and LED strips. What might be causing the vertical line?


You have wasted your time and money. The LED power supply and LED strips are only the backlighting. The only thing that might fix is a situation where you have a blank screen with the sound working.

If you don't know what you're doing, DON'T OPEN THE TV UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE TV IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.

TV TURNS ON,LINES ACROSS SCREEN THEN TURNS OFF BY ITSELF


sounds like a vertical problem, usually you'll see one white line across the screen, but one I worked on would come on and the bottom half of the picture was gone and there were lines across the top of the screen.

If you know how to solder & can find the vertical output chip then you could try resoldering the pins. If this doesn't fix it then it needs new parts.

Thin black line


Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.
