Has power, has sound, black screen... HELP PLEASE
PLEASE HELP ME!!!
OK I bought a LG 55LB5900UV-BUSWLJR 55” LED TV knowing the screen would flicker on for a second and stay black for 5 seconds then flick the screen on for 1 second and repeats as long as the TV is powered on.
Did my research and narrowed it down to bad LED lights and I would have to replace the strips. So I ordered brand new LED strips (made sure they fit my TV by checking the panel number and strip number) and installed them.
Now, when I plug up the TV and power it on the screen just stays black, but its powered on and has sound.
Two things I'm concerned with when I did the LED strip replacement :
1. When I removed the sheet that lays on top of the LED strips and the bulbs stick out of, the clips that hold it down were hard to remove and brittle so I broke the majority of them and didn't use them when I put the TV back together. Could that cause a problem?
2. After I installed the replacement LED strips, I had to reconnect the LED connections that power the LED lights. But when I removed the connections from the original strips, they were pretty snug and I had to squeeze the sides and pull up to remove them and it took some effort to do so. But when I tried to reconnect the connections, it wasn't locking into place and would easily pop out with any movement of the wires. All of the connectors did this so I taped them down with electrical tape and rebuilt the TV to see the black screen... Could it be that the taped down connections aren't getting a good enough connection to power the new LED lights, causing this black screen ?
LG 55LB5900UV - BUSWLJR... Have power, have sound, black screen.
Thanks in advance for any input towards finding a solution to the problem!!
Here are the boards.
This is a video of what's going on
Here is the P801 Connector
This is my current state with the tv. I don't have sound because my speakers aren't plugged up. Seems to get dimmer after a few flicks too. I can navigate the inputs, the channels, and the menu with the remote, it all just flicks.
Is it possible to get these LED strip connectors mixed up and still have enough power to flicker but not stay lit?
Is this a good question?
