Hello, everyone. Welcome to the video. These boards were removed from second-hand electricians who recovered them at low cost, and the better ones kept them, and the worse ones threw them away. Like this, the main boards are colored, and most of them are good, and most of the recycled televisions are broken. There are often ironic comments on the internet, and the maintenance is done by master changers. Personally, the era of scrap metal prices for accessories does not require time to repair and waste time。
Today we look at this 42-inch tv tcl in front, and there's a backscreen, a flower screen after changing the main panel. And that's why i picked an identical master plate。
• this can open the television menu, find the settings bar, then enter the factory model from the contrast and adjust the screen reference data. Find a contrast, enter 1950, then enter the factory。
• then find the fourth one and get in. When you click in, you find the one with the id on the back of the letter, because it's full of english letters and you can't read it。
• start adjusting the screen as soon as i find it. When i close the camera, should everyone see it? Now look at the yellow one, the yellow one is the screen, the second column is the type of the screen crystal tv, and the third column is the type of screen used by lcd tv. That's how it's going to be. It's fine。
• the television now replaced with the main plate is 4215200b1, and the number matching the television model is always found in the screen. Now show the 47 inches. Keep looking, keep looking, keep looking. The data it displays and the type of television that replaces the main panel are the same when it reaches the 28-bit serial number, and it can be determined at this time。
• then turn off the tv, turn it off and re-open it to see if it is preserved. Second turn on, so that even if the adjustment is complete, the screen data modification is successful。
Open the menu and look at it. It's normal. There's no blue screen。
Thank you for watching。
