D900i display fault

[cellshack]

I replaced the Charging block on the D900i, but now the LCD is not displaying.

Any assistance with this problem would be appreciated.

Also very URGENT!!!!!!!!

What is the point of posting a problem if nobody is going to help me!!!

Same problem. Any solution yet?
The lcd & Flexi are 100% but display is blank. Main board fault.

Cos everyone knows you used to much heat on the board and stuffed it up! U'll need the replace that mainboard....

I've been repairing phones for the last seven years, so I think that I know what I'm doing. If that is the problem, why has it taken so long for anyone to reply. I have this problem all the time, waiting and waiting for help, but in the end I have to dissapoint my customers, because nobody tells me what the problem is. I have access to plenty af spares and mainboards so I have already replaced the mainboard for the customer, but that is beside the point.

Really bro? Is that the case?

How about in my situation where the board was never worked on before?
There is no damage on my board that could possibly been caused by overheating.
The flexi & lcd are 100% working because I have already tested with another board. No physical or liquid damage on the phone at all. What do YOU think the problem is, & what wold be the solution?

P.S Before you say software, let me just point out that I have already flashed the phone with good working flash files & eeprom & have made sure that the imei is fine...

At least one person has offered a possible solution to try, here it is:-

First of all, learn how to replace a system connector properly. I've replaced hundreds of system conn and never broke a single phone. Tell you what make a video of when u replace the block then I'll make one then you can see how to do it properly. What tools do you have?

Why would I say this is software? You got the phone it was working, you did hardware repair and now phone is not working. definately not software...

Have u tried this??? this is doesnt make any sense! LCD is controlled by main CPU only! Why would u change the power IC if the LCD dont work? And whats liquid on the bluetooth module have to do with the display? Have read the schematics???? Does birkes know how to read schematics??

@cellshack
Send me that board if its not to much trouble.... pm me

No offense intended...

@ NAZTY
Where is your shop if I may ask...

[NAZTY]

@Speed_Demon
No offence intended or taken

FYI If you read my post it clearly states "in my situation where the board was never worked on before?"
How then would you explain the board been damaged by overheating?

I donot have a "shop" bro, I have a repair lab that is fully equipped you automatically assume that I am a beginner when in fact I have been in this game for around 12 years & have trained many excellent technicians & still offer advice & support on a daily basis. I am very confident with my ability as a technicain & can reliably & precisely replace a simple connector with ease
The 1st thing I teach my technicians is to identify the problem 100% before offering a solution

I asked for a solution, not a pi$$ing contest & as you read in my other post I have two d900i's with the same fault & there is no liquid, impact or any other vissible damage to the boards, it seems to be a common problem & thats the reason that I asked if anyone had a solution. I am also sure that the cpu is not the "only" component that would effect the display functioning 100% or controlling the lcd, Check your schematics carefully I'm sure you will find the same

Anyway thanks for the reply, When & If I do sort these two phones out I will post the solution, I have purchased both phones from the customers so that I can experiment a bit

Cheers for now...

Hm...what is the point of suggesting some solution if nobody take it for real...it is not always some software, eeprom or etc solution, and yes, a few more components are responsible for lcd(like video chip or CF).

Cheers,

Do me a favour, Take photos under microscope of baseband, power IC, flash, and the area of the system connector and post.... I'd like to have a look at it... (take photos around the above mentioned ICs)
