Today I received a 58-inch long-distance LCD TV LED58C3000ID
Qime 58-inch LCD module
gray screen display, the sound is normal. Since I have accumulated a lot of LCD knowledge in normal times, I directly disassembled and measured the working voltage of logic board , VGH=0 VGL=0 VCC=12V, the chip does not cause heat and hotness, and the logic board has 2 cables and connected to 2 LCD edge boards.
will be removed, and then the computer is turned off and the left side is removed, dash! The screen has changed, half of it is displayed and half white, and then the cable on the other side is replaced, which is the original fault phenomenon. The analysis is that there is a problem with the Y axis or edge plate on the left side of the screen. Run the line on the side board, no short circuits. I had to disconnect the VGH power supply on the left, install the cable, and display the full screen.
just the left tail is dark. I heard that Qimei Screen has symmetrical ears (TABs) on both sides above 32 inches, and it is tearing. Carefully disassemble the large frame of the screen, do not take out the LCD glass, and insert the card into the gap between the left side of the screen. Then hold it with your fingers. I saw the 6 ears on the left, tear them one by one, tear them one by one, turn them on and take a look:
dark area shines a horizontal area, basically tear them which area is the best to have the jurisdiction. It will be normal to tear it all.
But there are 2 very thin bright lines in the middle. Look carefully at the left and you can't see the point on the right. It is probably because of the Y-axis design of the large screen. Instead of scrapping it, I have to do this. Unlike the front-line screen damaged by LCD, most users can still accept it, and install the screen. Haha, the screen effect is pretty good. Play a blockbuster movie and put a few pictures of repairing roast chicken for everyone:
Is the flight attendant beautiful? Attached warning: Tear ears can only be used for more than 32 inches, and only if there are symmetrical ears on both sides can be successful. If you tear up one side, if you tear up the wrong side, you will scrap the LCD if you tear it below 32 inches, and it will end up in failure. Yueyang Yi
