How to rework Launch DiagunR71 chip PCB

Topic: Damaged main board R71chip of Launch Diagun. (Professional advice needed.)


I bought used Launch Diagun and one of them has damaged the main board. On/off switch needs soldering and below that switch there is a tiny chip called R71, which broke off for previous user.

Does it contain any specific information/data for diagun or is it generic and interchangeable chip which i could take from a different kind of chipboards? I mean, as long as the name of the chip is the same R71, can I take that R71 chip from not diagun board and use it in diagun?

If not, can it be programmed and then used in diagun?

Sorry, I have no clue about chips and looking for professional advice. Thank you in advance.

R71 is a 100 kOhm SMD resistor, can desolder it from any electronics, it is usually marked “104”.

If Launch Diagun freezes, common problem with firmware, flash needs to be reprogrammed.

Here is chip code and I was told by ‘Gazownik’ on this site that R71 is 100kOhm resistor.

Hope that this helps. Thanks.

Uninstall windows update based on given date

Windows update removal during the test phase became hectic for Administrator. each update needs to be removed manually and it is time consuming.

This script will remove the update based on the specified date where windows update is installed.

$update = new-object -ComObject Microsoft.update.Session

$Collection = New-Object -ComObject Microsoft.Update.UpdateColl

$Searcher = $update.CreateUpdateSearcher()

$Installer = $Session.CreateUpdateInstaller()

$pending = $Searcher.Search("IsInstalled=1")

foreach($entry in $pending.Updates)

$installeddate= $entry.LastDeploymentChangeTime 

   $installeddate= $installeddate.ToShortDateString()

    if ($installeddate -eq "7/10/2017" ) {  

    $Kb="KB",""

  $B= $Kb -join $entry.KBArticleIDs

   #$a+=$entry.KBArticleIDs

    $TitlePattern=$B

    $Searcher.QueryHistory(0, $Searcher.GetTotalHistoryCount()) |

    Where-Object { $_.Title -match $TitlePattern } |

    ForEach-Object {

        Write-Verbose "Found update history entry $($_.Title)"

        $SearchResult = $Searcher.Search("UpdateID='$($_.UpdateIdentity.UpdateID)' and RevisionNumber=$($_.UpdateIdentity.RevisionNumber)")

        Write-Verbose "Found $($SearchResult.Updates.Count) update entries"

        if ($SearchResult.Updates.Count -gt 0) {

            $Installer.Updates = $SearchResult.Updates

            $Installer.Uninstall()

            $Installer | Select-Object -Property ResultCode, RebootRequired, Exception

                    }

    }   

    }

Trouble shooting the Application Catalog

Trouble shooting the Application Catalog

Issue Identification: http://<sccm servername>/CMApplicationCatalog is not displaying the Catalog Content

Site Roles involved: Application catalog web service point and application catalog website point

Site Status Critical: Application Catalog website point

Component Status Critical: SMS_PORTALWEB_CONTROL_MANAGER

Error Found: http://localhost/CMApplicationCatalog/default.aspx is displaying error in default website in SCCM Server

Log files: smsportalwebsetup.log

Solutions which didn’t work 

       Reference from internet:

Browse to the Windows\Microsoft.NET\Framework\v4.0.30319 folder DOS.

Run the following command:

aspnet_regiis.exe -i

After that restarted the sccm services but still component in critical state and log shows the same error

Note: Latest one dot net version should be used for the above command ( ex: 4.0 in my case)

So reference from internet didn’t helped here

       Removing the role application catalog website point(which is critical in site status)  and readding the role also didn’t help

 

Solution did worked 

So thought of doing the manual installation with all parameters to track the error in GUI Mode

Command line used is d:\Program Files\Microsoft Configuration Manager\bin\x64\portlweb.msi

PORTALNAME="CMApplicationCatalog" SMSSSLSTATE=0 PORTALLANGPACKFLAGS=0

PORTALLANGPACKFOLDER="d:\Program Files\Microsoft Configuration Manager\bin\x64\catalog\"

PORTALPATH="d:\Program Files\SMS_CCM" PORTALLOGMAXSIZE=8000000

After this checked the url http://localhost/CMApplicationCatalog/default.aspx in SCCM Server , I can see it loads the application catalog web page but no application were listed with permission error info.

One main thing is Patience. Log will display as installation was successful but if you look at the task manager still rolesetup.exe is still running. Once rolesetup.exe is exit from task manager we can check the url again

Bingo it starts working now

Check Machines in SCCM not in AD

Get all the computer in SCCM put them in a variable do a for each and ask AD if the computer is found and active. If not delete it form SCCM.

import-module ActiveDirectory

Import-Module $env:SMS_ADMIN_UI_PATH.Replace(“\bin\i386″,”\bin\configurationmanager.psd1”)
$computers = (get-cmdevice).name
foreach ($computer in $computers)
{
try
{
Get-ADComputer -Identity $computer -ErrorAction Stop >$null
}
catch
{
write-host “$computer is not in AD”
}

}
