My laptop turns on, but I see no video?

My laptop turns on, but I see no video?

This issue can be pinpointed to two separate items very quickly.

If your laptop will display a video on an external monitor, then you have a hardware issue with either your inverter or your backlight.

You can change the CCFL, which is referred to as the backlight, by disassembling your LCD screen and clipping the AC contact wires that are white and pink. New CCFL bulbs have to be soldered in after clipping. I get asked if inline butt splices will be crimped in and applied instead of soldering. With each system having different clearances, I see that as highly unlikely.

To change an inverter bar, you simply match model numbers and unplug a molex connector.

If it will not display externally, then your issue is geared more towards a BGA onboard issue. HP DV2000, DV6000, DV9000, TX1000, Dell D620, D630, D630, D820, D830 systems with Nvidia chipsets have the known BGA issues that I can fix.

Most systems need a double or triple chipset reflow.

If you are experiencing this issue and need an answer to why it happens or more detailed information on the issue:

Do you add copper shims or pennies?

What if my need is not listed?

As an electronics technician, laptops and desktops are not the only items I work on. If you have a specific need that is not listed above, please feel free to email me at

Copper shim question – Do you add copper shims or pennies?

This section will try to answer the most often asked questions I get.

Copper shim question – Do you add copper shims or pennies?

Your issue with the onboard BGA chipset is heat related. HP DV2000, DV6000, DV9000, TX1000, Dell D620, D630, D630, D820, D830 systems with Nvidia chipsets have the known BGA issues that I can fix by reflowing them.

Now, the question above is asked to me constantly. I personally do not use copper shims.

Copper shims and pennies before 1981 do not fix your issue, but do more to hamper it.

You will have three things that can happen. These are an electrical arc, an overload, or a soldering issue.

Your chipsets on your laptop 9 out of 10 times are fine if that have not been worked with in anyway and can be reflowed properly. The chipsets have capacitors located on the top and these capacitors are actually made of ferrite. When you apply Artic Silver and the copper shim in direct contact with your chipset you have stress fractures or arcing. Heat will cause the chipset to move up and down, by design, and will cause the copper to flex causing the capacitor to complete a circuit arcing between the chipset, the shim, and the heatsink which has copper in it. Placing a plastic spacer does not help any since the heat will melt, deform, or damage the chipset in its own right.

Now your chipset may get an overload and burn it out internally with no outer signs. Usually on a DV6000 system you will see a three capacitor cluster on the motherboard overload, and burn the planing of the motherboard. Overloading will cause the chipset to pull more power in the board causing stress on other chipsets such as the MAX8774, Max8724E, and MAX8734A.

The simplest issue is that your chipset will heat and the shim causes the solder to glob or puddle on the underside of the chipset. There is a reason the CPU is 5mm and the GPU is 3mm with no need to place a copper shim in to damage that design no matter how poor it may be now or before.

Ryan,

This email will serve as an update on the status and repair of your systems sent in.

Currently I have listed the following machines sent in for repair by you:

HP DV4-1220US with the serialization of CND9042Z86

As agreed your system is billed at $125.00 per system.

Now, with the HP DV4-1220US with the serialization of CND9042Z86 has been reflowed. The system board was labeled HP SPS 511858-001. The system reflowed on both the AMD Radeon IGP 0840 chipset.

After the reflow of the chipset, we noticed your system was not working correctly. We ran our diagnostics software on the system and found it came back with the following error. Your processor was found to be failed and damaged. The processor was exchanged, and found the new processor caused the system to display a repaired system.

Please keep in mind you need to reapply thermal compound such as Artic Silver 5. You also need to update the video drivers from Nvidia.com and the BIOS from HP if one is to be applied. Please advise your end user to purchase a cooling pad to help insure the removal of heat from the system.

If you need more help in explaining these areas to your end user, please visit http://www.doubleclickittofixit.com/tips.html

Pictures of the repair can be viewed at http://www.doubleclickittofixit.com/img

The system repair can be found here along with the explanation of how we repair systems in our shop and what we do to process the repair. The HP DV4-1220US video displays our system, repair processes, and what settings we use with our IR system to reflow your system.

Reflow and reball of PS3, Xbox 360, and laptop system boards after being fluxed and heat gun/hot air gun attempted.

Here is a new video that I produced displaying a few systems, mainly PS3 and Xbox 360, that were worked on previously by a few home users. The system boards were fluxed, hot air heated, heatsink damaged, and more issues. This video displays greatly why hot air videos on Youtube and tutorials are damaging to a system board. Now, I receive a number of emails saying “But what if I use aluminum foil wrapped around my board then ….” My answer to them is always check out this video because I was told some of these boards were wrapped in foil and heated with a shrink wrap hot air gun from Lowes.

Updates for my clients as of May the 3rd

Currently our facility has been deemed structurally unsound.  This means we are not able to retrieve any property from that facility without the building inspector granting us permission to enter.  FEMA has currently declared our offices  damaged beyond repair and we are working with them to help expedite claims for our shop also.  Our lawyers are in negotiations with our local township to fulfill request to obtain personal property and get our insurance claims processed in a uniform fashion.

For us to file insurance claims, we need our clients whom have systems in the shop to resubmit paperwork electronically to james@doubleclickittofixit.com so we can process all claims.  We currently have cellphone access, but internet access has not been restored.  We currently are checking our emails off site and out of the North Georgia area once a day.

For our future and other clients, we are in negotiations to get a new office located in our city.  This negotiation has not been complete but should be complete in the next week or two.

 

Our plan is to rebuild and we are in the process of just that.

An update for all my clients whom have asked for updates since April the 27th

As an update for all my clients:

A series of tornados touched down and leveled our city of Ringgold last night. Due to this storm, we at Doubleclickittofixit.com have became a casuality of this storm also. We are being told at this time that efforts are underway to restore our city of Ringgold back to a functioning state, but this may take three to five weeks. No one is being let into the city, and those that are currently are within the city limits are asked once they leave not to return until the timetable is ended.

How does this affect you as a client?

If you have sent in a system, we are not able to give any status updates. Due to the pictures we are going to post, we can naturally assume your systems are not doing well. They are not water damaged, but probably missing completely. Currently our cellphone service is also sporatic in nature along with email and online support so please keep this in mind when calling and leaving messages or writing emails.

Below are a few of the pictures from our shop as of this morning:

UPDATE: ANOTHER eBAY SELLER WITH A COPPER SHIM REPAIR FAILURE!!!!!

I have stated time and time again to my users why I do not use copper shims. This is a prime, grade A example of what can, will, and does happen with copper shims.

This laptop came in from an owner whom brought their laptop to me from Dalton, Georgia. A copper shim was placed on his system from a laptop repair center from the United States that he used off of eBay. I am not naming names of the offending company, but I will post the pictures.

DO NOT USE COPPER SHIMS! As the pictures display, this copper shim damaged the system. In previous examples the system displayed a damaged and cracked chipset. This system displayed a overloaded capacitor issue. This happens when the power coming in the system is modified due to the chipset not failing due to the copper shim. In short, the copper shim does not let the chipset overhead or fail then the power just amps up and causes a system failure.

This failure occured within the MosFET area labeled AO4407 and a three capacitor cluster. This failure is unrepairable due to the planing within the layers in the motherboard.
