a venue I used to work in has a outdoor p10 led screen.
Some of the modules are acting up so got some spare ones from China, now the problem is that the new ones are only half working as in only half the module is lighting up.
Any ideas are very welcome

Is it exactly the same fault on all the new modules?

Can you describe the fault in more detail, is the fault on one side / top/ bottom etc. and all the same position across the new modules? Are they not showing any image at all, or are there speckles / noise etc?

Is the software side ok? when you say modules, are you talking about sections of the LED array or receiving cards / processors PSUs etc.

Have all new components been given the same files as the originals?

Keep pushing on, things are gonna get better.

I know precious little of led screens but thought this should be easy to swop over the modules.
I have tried three of the new ones and it's the same on all,the right hand side is working and nothing on the left.
Modules are 160mm x 160mm rgb p10 and use a 16 pin idc connector.

From that website 

You’d better buy all modules at a time for a led screen, in this way, we can make sure that all of them are of the same batch.
For different batch of LED modules have a few differences in RGB rank, color, frame, brightness etc.
So our modules can’t work together with your previous or later modules.
If you have some other special requirements, please contact our online sales.

If you only plug in the new modules do they work properly? As mentioned before, have you resent the map to them?

blah blah blah blah blah......

And have you tried the new modules in different locations in the screen, or always the same location with different modules?

When the new module is in, is the half that is working showing the correct part of the image?

Keep pushing on, things are gonna get better.

Yeah I have tried the modules in different areas of the screen.
It does look like the image I'm getting on the working half is correct but difficult to tell on a p10LOL
The boss man said he would take a chance on these as sending modules away for repair would cost a ton of money.
The plan was to take the working good ones from the bottom of the screen to replace the bad one scattered around the screen so at least if the new one are different brightness or colour it mightn't look too bad if they are all together.

Swap the PSU out and give that a try. 

One of my panels was being a pain, tried loads of things. Then tried swapping the PSU for one out of a donor panel and this solved it.

I guess you know that you cant really swap old LED modules for new ones as they will be a different batch and stand out like a saw thumb when playing content.

If you ever want to chat video give me a buzz. I seem to be falling in to supplying LED video walls for all sorts of events at an alarming rate.

Video is usually something I stay well away from, but I been lumbered with this.

Yeah I know it's bad to mix modules but the plan were to put the new modules in a line on the bottom of the screen and use the good ones from there to replace the bad ones in different areas of the screen.

Changing power supply's has done f all for it

The next thing I might try is to do a new file configuration for the screen as I discovered that if I swapped out a bad module for a good one,it hasn't fixed it,and that included swapping power supplies and ribbon connectors.

The guy that sold the screen said originally that only 2 or 3 modules were bad,but when it was powered up ,there is at least 9
But this screen was sitting in storage but about a year.

The new modules were only €20 a piece so the boss thought it was worth the risk to buy 10 of them.
Have a lad with experience of the screen coming tomorrow,so here's hoping

It seems like you're facing an issue with the outdoor P10 LED screen at the venue you used to work in. It can be frustrating when some of the modules start acting up. Getting spare modules from China was a good solution, but it's unfortunate that the new ones are only partially functioning, with only half of the module lighting up. This situation requires troubleshooting to identify the cause and find a suitable solution. It might be helpful to consult with professionals or experienced technicians who specialize in LED screens to diagnose and resolve the issue effectively. you can also get help from
