The N72 phone was broken, and there was only a bright light and no information when it was turned on

If you can hear the boot sound when you boot up, it means that there is no problem with the motherboard of the mobile phone, and the white screen is displayed without the image when you boot this phenomenon has seen a lot, generally the screen is not broken, but the screen circuit board above the screen is broken, this situation can not be repaired, generally only the screen is changed, if there is no sound when booted, it is best to get the customer service test, the customer service test fee is 20 yuan.

The screen is broken. Go to customer service.

You can try to format it, my phone also has this problem, format it and it can be used normally.

Formatting is divided into soft and hard compartments.

The soft grid is entered in standby*

The default password is 12345

The hard grid is when the machine is turned on.

Press the same three keys and dial keys).

The word formatting will appear on the screen (I have never seen this word in the hard grid) Note: 1. Make sure that the battery is sufficient when the grid machine, once the power is off when the grid machine is turned off, the consequences will make you very troublesome.

2. Please back up your business card holder on your mobile phone before the grid.

It is recommended that you still repair the maintenance cost should be said If it is less than one-fifth of the machine, it is worth repairing because the N72 is still very popular and does not belong to the obsolete model Besides, the cost of buying the machine is too great It is more cost-effective to repair it.

Your screen is broken, it's OK to change it!

Contact the problem, if you are still under warranty, go to customer service to see.

After the warranty period, it is called to repair the disassembly of the mobile phone to wash the electric shock.

But if you want money, it depends on the landlord's ability to bargain.

72 often like this...

I'm used to it... Smartphones are just that.

You are the circuit in the motherboard contact broken, so the power consumption will be large, repair about 200, it is best not to use it before repairing, the battery consumption is a safety hazard.

Doesn't it mean that as long as it is a Nokia mobile phone, it can be guaranteed in the whole country? As long as the warranty period has not expired, it should be fine!

You flash the phone and see, if the problem is solved, it will be fine! If it doesn't work, there's a hardware problem! There's no way to fix it!

It mainly depends on what the phone is. Domestic machines will be relatively cheaper, brand will be more expensive, if it is an iPhone, it is difficult to say......

Dear, it's broken! The most serious thing is that the motherboard is broken, and that costs a little more, so it's better to buy one directly! But it shouldn't be a big problem to fall!

It may also be that a certain line has fallen, and they may have a price of 30 yuan to repair the mobile phone, and I have repaired it before, which is a fixed price, and it is recommended that you go to a few more to ask, and I wish you good luck.

Look at what kind of mobile phone it is, if it's a feature phone, it's not worth repairing.

It should be able to be repaired, so take it to the repair shop and take a look.

Normally, it's a data problem.,It's a serious point that may break the motherboard.,You try to format the machine.,If it doesn't work again.,I have to take it out and fix it.

Tray? I really don't know what to say.

Either the monitor is broken, the wire of the screen is broken, and the soldering is off. Just take it and fix it.

I guess I can't fix it, don't fix it, let's change it! It is recommended to change to a 5360XM or N79, which is very cost-effective.

It's broken.,Take it to repair.,It's not good to ask.,Software,Power,CPU,Font library, etc. may not turn on if it's broken.。

In fact, you can completely fix it yourself. (No money).

If it really doesn't work, you can go to a small repair shop, about 7 to 30 (including good phones), but don't go to a specialty store. Overhaul between 20 and 100 (including good phones) and do you have a warranty card??? You shouldn't want money, and even if you do, it's about 0 10!!

My phone was broken for a month and didn't cost me anything to fix it.

It depends on the person who repairs it.,If you don't change the keyboard, 10 or so should be enough.,But he said that if you don't repair it, you need to change the keyboard for dozens of dollars.,That's no way.。

Domestic machine 30-50 yuan.

80-150 yuan for foreign aircraft.

Note: A broken power on and off button may also be a circuit problem.

You have to see who repairs it, as well as your phone model!

Be clear about your phone model.

What mobile phone please?

Different phones** are also different.

Say less about a dozen or twenty.

It's also possible to meet hundreds of profiteers if it's expensive...

Big brother, what kind of mobile phone are you?

Hehe. If it's repaired, you'll give it to me. To summarize, what you said is not that the hardware is broken.

It can be solved by flashing. If the warranty period is not over, you don't need to spend money to repair it to customer service. The second is that you have to go to the mobile phone repair shop to brush it.

If the shop is small, it is best to go from Friday to Sunday. Because they want to get a big mobile phone store to swipe. That way you don't have to wait that long.

Generally 20 to 50 yuan. See if you'll be able to haggle the price. Finally, I wish you well.

KF is very expensive, not to mention Shanghai, the question is in the line, how much do you estimate how much a line can be worth? It is estimated that the money charged to you will be 10-20 times the price of the cable itself.

Most of them are loose display cables! It's good to reinsert it cleanly, if it doesn't work, you have to take it for repair, and talk to him about the price, that's the only way!

Change the line, the original is almost 200, and the defective product is about 50 (in the roadside shop), which is still the original and easy to use.

It depends on the situation is a problem with the mobile phone cable, and it will be about the same for 50 yuan!

Wire problem: If the cable is loose, take it to repair it and give a hard fee. If it's broken, change it to about 30. I'm right, trust me.
