Learn how to fix the Realme 3 no display issue by identifying and repairing a faulty resistor causing IC overheating and display failure.

Key Takeaways

A faulty resistor near the coil can cause the Realme 3 display to fail by overheating the IC.
Testing with a different display helps isolate the problem between screen and motherboard.
Checking capacitors and resistors with a multimeter is crucial before replacing expensive components.
Replacing the damaged resistor with a jumper wire can restore display functionality.
Proper diagnosis avoids unnecessary IC replacement and saves repair costs.

What the video covers

The video addresses a Realme 3 phone with no display graphics despite powering on and vibrating.
The presenter tests the phone with another display to rule out screen damage.
A multimeter is used to check capacitors and resistors for shorts, finding none initially.
Rosin is applied to the board to observe heating issues, identifying a specific resistor heating excessively.
The faulty resistor near the coil causes the IC to overheat, preventing the display from working.
The damaged resistor is removed and replaced with a jumper wire to restore circuit continuity.
After repair, the display works correctly, confirming the resistor was the root cause.

Chapters

What causes the Realme 3 phone to have no display despite powering on?

The no display issue is caused by a faulty resistor near the coil that overheats and causes the IC to heat up, preventing the graphics from appearing.

How can I check if the display or motherboard is causing the problem?

You can test the phone by attaching another known working display to see if the graphics appear, helping isolate whether the issue is with the screen or the motherboard.

What is the recommended repair for the faulty resistor found in this Realme 3 model?

The damaged resistor should be removed and replaced with a direct jumper wire to restore the supply path, which resolves the heating and display issues.

Speaker A

So, hello friends, how are you all? Welcome to your YouTube channel, One Mobile Solution, and today we have a Realme 3 phone that has no display.

Speaker A

There are no graphics, and it has been returned from a shop. So today, in this video, we will look at it. This phone is turning on. You can also see the voltage on the digital charger. And this phone is vibrating. It is turning

Speaker A

on completely. But there is no display on it. I have also tried checking it by installing another display. Now I have checked it. I will also tell you what the fault is and how it will be repaired. So keep watching the full

Speaker A

video, and if you are watching our channel's video for the first time, please subscribe to the channel. You can see I have opened the board, and work has already been done here. In its graphics section, I will show it to you

Speaker A

a bit more clearly. And I have checked here with a multimeter. There is no shorting on any of the capacitors here.

Speaker A

There is no shorting on the resistor either. But when I connect the display to it and turn it on, it heats up quite a bit. I will show you that check.

Speaker A

Using rosin. How it is heating up. So keep watching the full video, and if you like the video, please like it and subscribe to the channel as well. So I will just apply rosin to it normally. I just want to tell you what the fault is

Speaker A

. Instead of working directly on the IC, because the IC is also heating up.

Speaker A

But I will check what it is being caused by. You can see this, I have applied rosin to it. I will fit it into the board, fit the board, and attach the display. You can see this, watch this. I will also take a picture of it

Speaker A

and send it, I will add it to the video. You can see this, you watch it too. I will make it a bit clearer. For now, you can see, now I am putting it on charging or turning it on, let me just

Speaker A

put it on charging. You can see this, as soon as I put it on charging, it is heating up from there, and this capacitor which was a resistor was heating up a lot and had turned red as if it were shorted. So it is causing

Speaker A

the problem because of this. You can see, and I will tell you more clearly which capacitor is burnt in it. It is burning. It is giving off smoke. And this is the reason why the IC is heating up. And all these other

Speaker A

capacitors are okay. And this black resistor is the one that is damaged. So, we will remove it. And this resistor allows the supply to pass through it.

Speaker A

But this resistor has gone completely dead. So, we will remove it and place a direct jumper. I will remove it and speed up the video so it doesn't get too long. And you will get complete information about it as well. Instead

Speaker A

of working directly on the IC, let's check the capacitors and resistors first. I had also checked the coil properly because this returned from another shop. And first of all, you should check it by attaching another display. I had checked it. You can see

Speaker A

this resistor here. Which was heating up a lot, and because of this, the IC was heating up. I have removed it. I will jumper it and show you. One moment. See where the jumper needs to be placed. Let me make it a bit clearer.

Speaker A

You can see I have cleared it; it was placed near the coil where this black resistor was. We will connect the points, short both with a jumper, and then check. You can see I have jumpered it. Let me show you. You can see it

Speaker A

more clearly now. I have done this jumper. You should be able to see it.

Speaker A

You can see it here. So, I have jumpered it. If you encounter a similar fault, you can fix it this way. I will place it back into the board. And the other display I checked with it. I have

Speaker A

a broken display. I don't check with that one. I have doubts about that display as well. So, I will check it. I have connected the display, and I will turn it on to see if the graphics have appeared or not. Otherwise, that

Speaker A

resistor belongs to the light section. That was the reason it was causing issues. And perhaps the board is not fixed properly in the body. So, let's put it on charging. Then we check. I have put it on charging. And you can

Speaker A

see. The display has come up. The graphics and everything in it are okay. And you can see this. It is working for us. Now, let me know in the comment section how you liked the graphics and the video; if you liked it, please like

Speaker A

it and subscribe to the channel. And let me show you clearly once again. You can see that this was the fault. The resistor right next to the black coil was heating up too much, which was causing the IC to heat up as well. The

Speaker A

graphics were not appearing. Thank you for watching this video.
