Samsung HD103SJ repair

Yesterday, 30.04.2013, before my program ends i ran into a problem one Samsung HD103SJ (1 TB HDD) was not working...

So i took that HDD and connected to my computer but nothing happend i couldn't see it in device manager... i've checked the cables to be connected properly and they ware connected ok.
I've rebooted the computer and entered in bios to see if the motherboard is seeing that HDD - no luck there also.

The laptop started to be slow like an old computer... so i've started to test what can be the problem with different tools.
So after running a lot of tests i decided that i'll have to change the hdd from this laptop because the one from the laptop is failing and it will crash soon.

How to fix an lcd monitor

The story:

One lcd monitor that is not showing anything but the power led is on. By removing the cable from the source (video card) normally on the screen there must be a warning that there is no video source connected.

Note:
If you are disconnecting  the cable from the video card and you have an adaptor on the cable you should remove that adaptor. From experience i know that if you have an vga-dvi adaptor on the cable that warning regarding the video source is not showed.

The cause:

When the power led is on but on the screen you don't have anything usually the problem is bad capacitor or a fuse.

Bad capacitors

The story:

One of the guys from the security company that is protecting the company that i work for asked me if he can bring me his computer because is not working and it is making some weird sounds.
After a few days he brought his computer in one bag and left it in my office...he did like this because he was in the night shift.

Powering the computer

After connecting mouse, keyboard, monitor i have pressed power button and waited for something to happen, for some sounds because the guy from the security said that after powering up the computer it's  starting to make sounds -  and i heard the speaker beeping.

After removing the side panel of the case i could see the components and notice that on the motherboard there are 4 capacitor damaged:
6,3V - 1800uF - 2 pcs
6,3V - 2200uF - 2 pcs
