Good idea and take pictures of the card with solder. Maybe its a component mount problem or a bad solder. Someone could see something you missed.

Can anyone please tell me if any soldering issue might have caused my screen not to display anything? (The light is on, on the screen but nothing is displayed)

I see no problem on this picture. Sorry, i hope something else will be able to help you.
Can you see any problems here. I bought two Makerbuinos and I tried to switch the screen and the light came back on
Thank you Jean Charles! I donât know why the screen isnât displaying anything⊠frustrating! I will see if anyone can help me with this! Thank you for your reply 
@August_Hilliger Youâre soldering doesnât look good around the screen connections, I would make sure youâre soldering iron is clean and clean off some of that solder on them joints⊠see the following imageâŠ

Youâre soldering doesnât look good my friend⊠see the following image, you can see the power switch is shorted and youâre screen solder joints look shorted too⊠try cleaning some of that solder from them joints.
Thank you very much. I will try that right now
It didnât work 
but thanks anyways
Iâm not sure but itâs seems on the picture that you could have cut 2 copper track by scratching the space between 2 solders. Itâs maybe a visual effect.
If the tracks are cuted, you will have to remove protective varnish by scratching delicately on each side of the crack and solder a jump
Else you can solder a wire between the start of the track and the end (itâs can be more easy maybe because tracks are easy to follow)

Okay, Thank you. I will try that later
Hey @bitfogav. I tried fixing the soldering. Here are two pictures but the screen is still not displaying things!
It turns on and now a black line appears for a second then nothing. Could you please help me figure out the problem? Iâve had this issue for a week and I need to fix it to be able to enjoy my makerbuino. Thank you!
@sak41 Can you check that the voltage regulator and the transistor are in the right spots? They both look identical except for the markings on the flat side(theyâre the black things with 3 wires that are bent over to the right of the screen), the one closest to the buttons should be the transistor and will say â2n2222â on its flat side. Also, do the ceramic capacitors(orange flat things that stick up on either side of the long silver thing right of the screen) say 22 or 104? They should say 22.
Also, check that the electrolytic capacitors(round tower things to the right and at the bottom) are facing the correct way, they are polarized which means they wonât work if theyâre put in backwards. The bottom one should have the thick white line pointing to the right and the top 2 should be pointing to the left.
Edit: Also, check that your resistors are in the correct locations, theyâre not polarized so they can face either way but they need to be in the correct spots.
Hereâs an image to help identify what Iâm talking about:
@August_Hilliger Check your transistor/ voltage regulator and ceramic capacitors as well, your electrolytic capacitors and resistors are correct.
@Dalemaunder hello! Thank you for your help!
I checked all components and they seem okay!
However, in your picture, R6 (down to the far right) seems to be a resistor of colors brown, red, black, black! However I put it as a brown black black golden resistor (as mentioned in the tutorial)
Which one is the correct one?
Any other help provided to solve this problem? :((((
Thank you
Full picture of front:
Thank you very much. They all looked fine, but I think I will try to resolder everything to find the problem
Whoops, Iâve put the wrong resistor there, it should have been brown/black/black/black/brown, good catch. Either way, that resistor is for the headphone jack and wonât affect the rest of the system.
Unfortunately, the only thing I can think of is either a faulty screen or an improperly flashed micro controller, do you have any breadboard equipment and another Arduino to test with? If not, youâll probably have to contact @albertgajsak and ask that he send another one your way, unless anyone else has any ideas.
In @August_Hilligerâs case, I think itâs just a dud screen, an improperly flashed micro controller wouldnât stop the screen from lighting up at all.

No I donât have any
I donât know how to fix this⊠itâs frustrating
I have used these Nokia Displays in other projects and found out that some of them are not working out of the box. The good thing is, that most of them can be fixed without any bigger problems.
First, make sure, that you followed all the suggestions above. (correct and clean soldering, choosing the right parts for assemblingâŠ)
If you still cant see anything on the display, you have to open the display to clean the rubbery bar which connects the small pcb inside the display with the display itself. Clean the contacts on the pcb (inside the display, on both sides of the rubber bar and on the lcd) with some rubbing alcohol. When done, carefully reassemble the display unit again and try if it works now. I had displays I had to do it twice⊠but most likely your display will be fine after the ceaning.
Hope this helps, Eskimo

@Jean-Charles_Lebeau, @bitfogav, @Dalemaunder, @eskimo, thank you for helping @sak41 and @August_Hilliger out.
@sak41, I think weâre still solving your issue and waiting for your reply in this thread here:
@August_Hilliger spoke with me via PM. Iâve told him to send me the photo of his MAKERbuinoâs front side but without the screen attached (I want to see the soldering joints on the microcontrollerâs socket).
@August_Hilliger, it might be better if you just post that photo here instead of PM-ing it to me.
Please donât worry, if this doesnât work, you will test your microcontroller and we will send you a new one if this one was mistakenly sent blank or was damaged in the soldering process.
In case the micro is working fine, Iâll send you a new screen.
