In our Tech Blog, we document some of the more interesting or challenging
repairs that we come across as well as providing helpful information.
February 20, 2011 • Updates
A general note to all of our customers (and potential customers):
Make sure that you have Windows updates turned on, and let the computer perform the updates! This is critical for closing security holes and keeping your computer as reliable as possible. The same goes for Java updates, Flash Player updates, Adobe Acrobat updates, and so on. KEEP IT UPDATED!
July 13, 2009 • LCD Monitor Repair
LCD Monitor would blink on and off after power up and would occasionally blank out. After opening the unit and inspecting the power supply board, four swollen capacitors were observed. This is a very common problem in modern electronics. Electrolytic capacitors are used in many devices. Please Note: This is not meant to be a complete guide to repairing an electronic device. If you are unfamilair with electronic concepts, you should seek assistance from a professional.
June 25, 2009 • Virus Removal
Customer complained of pop-ups and dire warnings on-screen of infections and data loss.
The computer had become infected with a virus in the Virut family. This particular machine had a rootkit (apparently in the MBR) that would survive the usual efforts to disinfect the machine. After some research, I decide that backing up user data and formatting the machine (including a wipe of the MBR) would be the most expeditious approach.
May 11, 2009 • Corrupt Security Descriptors
Customer could not log in and use his profile. Since Windows supports multiple users, it assigns ownership to files and folders for each user on the system. The customer could not log into his Windows XP profile. His documents and other data was intact; he simply could not log in using his account. There are several ways to correct this. Sometimes the CHKDSK process will correct security descriptor issues. In this case, CHKDSK did not correct the issue. I created a new profile and moved his documents and other data to the new profile.
May 5, 2009 • HDTV Repair
Customer contacted me and asked if I could replace some parts in an LCD HDTV. His HDTV was intermittently failing to power on when commanded to do so. He had found a number of people online who were experiencing the same problem, and one person had posted the fix, which involved replacing faulty electrolytic capacitors. He had the parts and the instructions but had no experience with electronics or soldering. We disassembled the unit to get to the power supply board. After noting the polarity of the existing part, I desoldered the faulty components and installed and soldered the replacement parts. We powered up the TV and success!
November 2, 2008 • Faulty Network Card
One of my business customers contacted me after noticing a complete loss of network connectivity. Upon investigation, one network switch port was showing a massive amount of traffic that was being passed to all of the other ports and switches. I first isolated the switch with the traffic. The other switches returned to normal. I then began tracing the cable that was connected to the port in question. I found a PC that had crashed and apparently suffered a network interface card (NIC) failure. The NIC was blasting random data into the network and had been causing a total saturation of the available bandwidth. After isolating and later replacing the faulty card, the network returned to normal.
