Usually the mask is easier to find, but the problem is that if you only replace a small part of the mask, there will be a difference in the color of the mask, which will cause a square to be displayed in the case of a black screen. It is recommended to replace the entire display.

280-320

​@@samzhou8510sir i tried the 280 to 320 temperature but it burns the led.. any suggestion?

Screen factory can be supplied

ask for the factory of the sceen. pad paper the pixel pitch and lamps size should be same with the module.

We can supply to you. Need to know the pixel pitch. Lamps size.

smd 2121It's I'm trying to fix it at home Can I have a small amount of soda

The product size is p2.5 smd21211 We're going to repair it as an individual, not commercial. We're going to buy a small amount of pcb pad and lead. If you let me know the product page, I'll buy it

“ledtechhub.com/zh/collections/tools/products/p3-91-copper-foil-for-pcb-repairing” you can check this website. but the price is not correct.if you really want to buy. we can change the price and you can order onside. we will shipping it to you.@@myungchongpark3189

ask for sales . after sales engineer have padpaper. also you can buy it from "taobao"

Of course you can, but if all 4 pins are disconnected, you need a 2*2 pad paper, because usually the power pins of the lamp beads are horizontal and the signal pins are vertical, so when you use 2*2 The pad paper can conduct the signal and power to the damaged position, allowing the lamp bead to display normally;

@@samzhou8510 thanks

multimeter

We have VN-480 product. 1/13 scan and 1/8, brightness 4500nit. ICN2153 IC are default deive IC .Which country are you from?

if possible . try to used Taobao . it's like amzon in USA in China.

We have . But actually just for used. Not for sales. The shipping cost too higher

china market

The power supply out power too small. Try to adjust brightness to 30% when connect signal cable. Then testing in white color.

@@samzhou8510 sir still its burning ic . Again colour missing problem

@@ranvirsingh6450 show me video pls zhousumin@163.com

The R G B signal with power are vertically crossed. Just test it on a multimeter

ask for which sell the screen to you the supplier

you should have spare part when you order led screen

@@samzhou8510 what is your wechat mobile

I need led bulbs how to buy sir

How many you need. “Pixel pitch. Lamps size. “We can quotes.

​@@samzhou8510I need to buy the paper

Have you tried the normal method to repair surface mount? To attach LED that fell off first clean/reflow the solder pads: apply flux, then solder with soldering iron. When pads look good and have enough solder add more flux, then place LED on top and use heat gun until solder melts. It may help to shield nearby parts from heat using pieces of cardboard so you only heat one LED at a time. Also turn down the heat gun fan speed. The weak mechanical strength sounds like a manufacturing problem, possibly not enough heat. You could try heating all the LEDs with heat gun or reflow oven (make sure all plastic parts are removed).

Yes, when repairing a P1.2 pitch led module, you need to be very careful because the beads are too small (1010) and the distance between the beads is also very small. At this time, you can only use a hot air gun to disassemble and weld new beads, usually using the minimum air volume and a temperature of 280-300 degrees. Some air guns may not accurately indicate the temperature, so you need to try raising or lowering them. They can basically melt the remaining tin on the solder pad in 3-5 seconds. When replacing the beads, you also need to pay attention to the direction of the beads because they are too small and it is not easy to distinguish their direction, and sometimes you need to use a magnifying glass; When welding, first use a hot air gun to heat the empty solder pad for 3-5 seconds, then place the lamp beads on the solder pad with tweezers, and use a hot air gun to rotate around the lamp beads for 3-5 seconds. Then gently push the lamp beads with tweezers. If the lamp beads can rebound naturally, it indicates that the welding is correct. If they cannot rebound, it indicates that there is too little tin on the solder pad or the welding is not successful; This is my experience sharing; Thank you for watching my video;
