Changhong LCD TV LT42710FHD left flower screen vertical line repair share this TV boot appears left side of the screen vertical line phenomenon, will repair LCD friends at a glance to see that it is a screen problem.
I was met today and I decided to find a way to fix it.
First you have to find the point of failure. I opened the TV, removed the iron frame, and now the screen cable, padded with the book, turned over the LCD screen and turned on. Since the fault point is on the left side, use your finger to gently move the outermost cable to see the blue screen on the screen change, indicating that the fault point is on this line.
So I took out a pressure screen head that I bought from the Internet and heated it with ferrochrome. At first, the ferrochrome is heated, and the pressure screen is used to drag back and forth at the point of failure, and then the test machine is powered on, and the line of the fault point is lightly moved with the finger, or the vertical line of the flower screen may appear. It shows that this simple heating pressure screen can't be stuck.
Suddenly, I thought that there is a portable sheet on the VCD's optical head cable. The sheet is heated and glued, which is convenient for plugging and unplugging the cable.
I immediately found a waste bald head, and dragged it back and forth with my heated pressure head, and then pulled it down with my hand. I am happy, this thing is very sticky! Cut a centimeter wide with the scissors, stick it to the fault point, and then use the pressure head to heat it up and down. The feeling is integrated with the screen cable. Try again after turning the power on, and manually move the cable, there is no vertical line fault on the screen.
This TV has been repaired in this way. I don’t know if this method is inspiring for everyone to fix the loosening of the cable in the future.
