Hola amigo tengo un problema con un panel, le cambie el ic quedo funcionando bien, lo guarde y cuando fui de nuevo a encenderlo no prende no da el tes. Me di cuenta que tiene algunos ic reventados volvi hacer la sustitucion pero igual no enciende

Hello Sam, great video, I see that you bottom half of the hole panel is a different color, I have the same situation were a panel looks pale compared to the other, I tried adjusting with LCT, sending the same RCG but it doesn't help, what can I do?

[@samzhou8510]

My cabinet in the video has different colors because they are originally two different products. By using smaller lamp beads and a wider range of black masks, the up if module on the cabinet has a higher contrast; I don't know what your problem is. It may be that the batch is inconsistent, or different products can be improved through manual correction of software, but it can't be solved generally, because the wavelength and visual angle that determine the color of the lamp bead can't be changed, and even if the equipment is used for correction, the brightness and color they agree on can't be guaranteed;

[@chucaswatjfan]

Generally, this is caused by the individual modules being manufactured with a different batch of LEDs. As far as I'm aware, it is not possible to adjust the individual modules apart from each other. The only solution is to ensure that all of the modules within the cabinet are from the same batch. From there, it is possible to adjust a whole cabinet to match the rest of the cabinets within the screen.

Hi Sam, great video, I have question, do you repair all brands led modules or only your company products. I have couple of p3 indoor modules for repair. If you do I wish to send you the modules and you can repair and send it back. Whatever charges is there will pay you.

Hello, good evening, greetings from Caracas, Venezuela, I am interested in knowing if you sell spare parts for LED screens and integrated RGB

[@samzhou8510]

Our company sells LED screen and plans to set up a display accessories sales department, but it is still planning at present. For led screen accessories, in many cases, the express fee is greater than the actual price of the accessories, so we are still considering how to reduce the express fee

Sir you are grate Q : how short is despair after put 5 v power you need a high -Am- to inject so when that done some or one component will be damaged but every thing work good how it could be !!!

[@samzhou8510]

Yes, so when there is a short circuit in some parts of the PCB, it is not easy to find them, because it may be in the middle layer of the PCB. At this time, the best solution is to provide a large current by short circuit, so that the small short circuit connection in the middle is burned, so that the PCB works normally. Of course, this operation is risky, because many times it will be burned together with other components, and it needs to be replaced, Therefore, it is not recommended to do this under normal circumstances. Before recording this video, I did not know the real cause of the module problem. Therefore, after some tests, I judged that the PCB was short circuited, so I did this. In order to complete this video, I recorded and released the process, and told spectator that was not recommended;

@@samzhou8510 Thanks I got it but you are don’t As you say short maybe happens in the line in middle layer so when you inject voltage the shorted line will cut then how every thing working good at your video after inject (cut )?? Because when inject done it well harm something Tanks for your time you are great keep going

[@samzhou8510]

@@mohamad-qh5px In fact, my operation resulted in the damage of a 74HC245 (control ic connected to R3), but it was OK after I replaced it with a new one. I cut this part in video

Also, where can I buy 3.9 masks?, the self adhesive ones

[@samzhou8510]

3.9 There is no self-adhesive mask, but there is a snap that blocks the lamp beads. Even so, there are screw holes on the mask. When you buy the mask, its color will be different from that of your previous product, which will lead to poor display effect

[@PROSLV]

@@samzhou8510 Thank you for your quick response, but can you please tell me where can I buy the 3.9 masks?

[@samzhou8510]

@@samzhou8510 and who is your mask supplier, or can I buy from you?

Yoww brother how are you I have trouble opening the back cover of module pl 2.9 outdoor absen i want to replace red ic i already remove screws but sadly i try to use your method it didnt work hope you help me

[@samzhou8510]

it's outdoor or indoor module? actually indoor easy to open the cover. and outdoor is hard. because it have screw foro mask. and also havery screw for PCB with cover. and that screw you can not see clear. because it's under the waterproof glue.

[@saoussene.screenstar]

How do you know where is ic driver and controller in the circuit ??

[@samzhou8510]

ofcourse . because it have types text on side. like MBI5264, this is driver. and also they have Special arrangement. and the control IC normal is 74HC245. and each module have few of that.

How to repair red colour shot in vertical line

[@samzhou8510]

There are many reasons for this phenomenon. Most of them are caused by the damage of a lamp bead. You just need to find the lamp bead and replace it. Sometimes you don't know which one is, so you need to remove one for testing until there is no red line in the test. That means there is a problem with the lamp bead you just removed, and you can replace it with a new one, There are also a few cases where the red driver chip controlling this area is damaged, or the red circuit is short circuited to the negative. This problem can be solved by replacing the driver chip or flying wire. The basis for judging the lamp bead or short circuit is based on the brightness level of the vertical red line. If it is the brightest state, it is short circuited. If it is bright, but not particularly bright, it is caused by the lamp bead damage;
