[Touch Diamond, MDA Compact IV General] siddharthsai:
Note : Hi, due to work overload i cannot be active on xda. If you want personal assistance regarding this problem, you can get in touch with me via twitter

Before you proceed, please note that I cannot be accountable/liable for any damage caused to your phone. This is only a guide!*:rolleyes:

THIS TUTORIAL IS ONLY FOR HTC TOUCH DIAMOND - NOT FOR DIAMOND2 / TOUCH PRO / HD2

( This is simply because i don't have these devices with me and that i haven't tested! Those who have a spare handset are welcome to send it to me for diagnosis )

Let me get straight to the point. I’ve found out the solution to all the screen blackouts or the famous “microp error”.:D I’m sure no HTC so called Technical department could solve this.

I’ve been sitting 40Hrs straight with my HTC Diamond. :mad: ( The worst part is removing the screw’s and putting them back.)

THE PROBLEM –

1.It’s a hardware problem. Upgrading the microp.dll will not solve anything. ( Microchips gives really wired errors)

2.SYMPTOMS : A dialogue box showing “ Microp version 0 , Upgrade firmware “ (as far as I can remember) , dim or no backlight , no charging indicator , No backlight for physical keys , no touch sense (D button) , soft reset button non responsive..

3.EARLY WARNINGS: (a). If u have dropped your HTC diamond , then there is an 87% chance of this happening. (b.) Exposure to extreme cold/heat. ( if it’s a heat issue then u might need to replace the motherboard.)

THE SOLUTION

I don’t have a cam to record the entire event. But there is a YouTube video of an HTC dissembling. I’ve downloaded the video and put captions in it so that it would be clearer. Video will be uploaded soon.

PROCEDURE

When you remove the back cover , you’ll see

1.The battery

2.Sim card holder

3.Tons of screw’s

Remove all the visible screw’s.Remember , your warranty will get void if you have one!! This tutorial is for ones without warranty. Take a look at this picture :

Remove the screw's shown above..

Next Locate the below chip.

www.twitpic.com/1cynw4

This chip is the main cause for the screen problem. This chip wen taken out has 2 connectors beneath it . These connectors wen gone loose causes the screen problem. It will take a few hours to just get them in place. ( HTC need to improve in build design)

www.twitpic.com/1cymhp . ( 2 connectors ) take out all the stickers if you want. Less annoying ..

Press it with your thumb (HARD) to ensure that they are in place. You can hear the click sound if you switch off your “Room” fan. Once this is done , put the battery without replacing the rest of the parts . ( All connections connected ) .. Try to turn it ON. If it doesnt , try again . Again it doesn't turn on then try again. Keep on trying. I'm sure that you'll get it working. IF it does turn on , please post reply's.

NOTE : Make sure that you connected everything back ( Very IMP) . For those who cannot take the chip out , I recommend you to watch a youtube video on how to dissemble an HTC diamond.

ATB ;)
