Samsung LA-46C550 LCD TV Service manual: https://www.manualslib.com/manual/893977...-La32c550j1f.html Analogue amplifier...

Probably motherboard issue so reflash the BIOS. They occasionally can become slightly corrupted. https://www.asus.com/supportonly/P8Z77-V%20pro/HelpDesk_BIOS/ Let us know how it goes.

From: https://forums.tomsguide.com/threads/fix-a-keyboard-on-maximus-lll.204610/ Thank you to Titan NOTE: If you need to type in a password to even get into Windows to do the following, make sure you attached an external keyboard first, to get past the password. Then disconnect the external keyboard and try the following... 1. Uninstall the keyboard driver. 2. Reboot the computer (without reinstalling the driver). 3. When it restarts, it should reinstall the driver on its own. If this doesn't work, you may wish to try connecting/reconnecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue. Also, if your device uses one, you may want to try updating the Synaptics Driver if the above doesn't help.

I think probably the hinge itself is good but it is rather what it is attached to that is the problem. You may need to disassemble the laptop depending if the problem is on the top or lower case. This one is a possible solution if the problem is on the screen assembly. It also explains removing the bezel around the screen: https://www.youtube.com/watch?v=kj7IbsAs... If the problem is on the main body of the computer watch below. Here is how to open the bottom cover: https://www.youtube.com/watch?v=8XU3BIJH... Note: This video shows the hinges but not how to fix or replace. This shows how to seperate the hinges from top body of case at about 14 minutes into the video: https://www.youtube.com/watch?v=neNLB_F7...

@Lucy Alexander Hi Lucy, Just to add another possible solution on the software/settings/driver side. Systems with both discrete and Integrated video cards will need both uninstalled. I have had very some tricky video problems with slightly corrupted drivers or settings. Just reinstalling the drivers did not correct the corruption or settings. The only way I was able to fix it was by using DDU (Display Driver Unistaller) to completely remove all traces: https://www.wagnardsoft.com/ After doing that I also run programs like Ccleaner anhd Adavanced System Care to mop up any other bits and pieces. A full anti-malware scan wouldn’t be a bad idea either. When you reboot you will or should get the default, generic Windows driver install. Update with the latest Nvidia one Hope this helps.

First it would help if you state the motherboard model and other specifications like RAM, etc. In this kind of situation “Post Code” reader cards are very handy as they will tell you where the system hangs. (1) O.K so probably not video card. (2) Does it have onboard video (this is where specs mentioned above help us to help you)? If so remove video card. Try one RAM module at a time in different slots. Any luck? (3) Disconnect hard drive, DVD drive, wi-fi cards, etc. (4) Reset CMOS by removing battery. (5) Let us know how it goes

You don't state exactly which model of the CQ62 you have but you may be able to replace the heat paste between CPU and heat sink. Compaq Presario CQ62-215dx CPU Replacement

Hi Glen, Here's the service manual: https://dl.dell.com/topicspdf/inspiron-13-7370-laptop_service-manual_en-us.pdf I'm assuming you are talking about the white connector on the motherboard as shown: Dell Inspiron 13-7352 DC POWER JACK HARNESS Replacement if so you must have used a lot of force. They are standard parts so perhaps browse through electronic supply web site for one the same size. Or you could try asking these people: https://www.parts-people.com/blog/category/dell-inspiron-repair-manuals/inspiron-13-7370/ Failing that, I would advise trying to find a local tech who would be happy to help a senior. Glen you just posted as an answer when it is a comment or question. Any how, just ask around. There must be people near you. Cars need circuit repairs all the time. It is a very simple job. Just align the male connector with the solder pads. TAKE A PHOTO - several. Do the other dud boards not have similar connector to scavange from?

There are 6 versions of Mountain Lion from 10.8 to 10.8.5. You don’t mention which one you have. Try downloading and installing OS X Mountain Lion Update v10.8.5 (Combo) https://support.apple.com/kb/dl1676?loca... After that Apples suggests installing upgrade to El Capitan 10.11 first. : https://support.apple.com/en-ca/HT211683 Look down the page for El Capitan 10.11 link to dmg file. Click on it and save. A note from Apple: “If you’re running Mountain Lion 10.8, you will need to upgrade to El Capitan 10.11 first.”

Enter the BIOS <F2>, I believe for DELL, and reset your clock. That should fix your problem. If not we will try something else.

Hi Vaughn, IFIXIT doesn't service anything. There are no fees, etc. Volunteers will help you fix your own equipment if you give us details such as make, model number, when the problem started, how it manifests, what you have done so far, etc.

These name branded external drives are the worst possible choice. Always, always purchase a SEPERATE case/controller and hard drive. Again, why? Often the branded ones have the drive’s circuit board and the USB port imbedded in the same circuit board. If that circuit screws up you are often lost. The component solution (like a good hi-fi sound systems) allows you to easily take the drive out, if the USB part goes bad, and recover your software in another system or case. If the drive dies replace it or upgrade to SSD or larger capacity. A no brainer!
