Repairing a Projector with Tinted and Washed-Out Display
My employer came to me with a little project. The office projector stopped working properly after someone touched the pins of the VGA video cable, and presumably released ESD energy into the projector. The picture’s colours were all tinted and washed out!
Note that the bottom monitor is displaying the same colour pattern
as the projector. Grey is completely missing!
He asked me if I’d like to take a look at it. My answer, as would be expected, was “of course!”
Quick Flip Fix
After a weekend at the Ottawa Pinball and Gameroom Show ’12, I came home to find that one of my Flip HD video cameras had stopped powering on. It functioned without problem when connected to the computer to copy the videos from it, but it would not turn on to record.
Today, I finally decided to open it up and figure out the cause. I suspected perhaps the power switch was bad, since it didn’t seem to be a major system failure. When I opened it up, the problem was as clear as day:
As you can see, something isn’t sitting quite right. One of the diodes became un-soldered, perhaps due to a shock, causing an already cracked solder joint to completely give up.
Simple enough to fix, a quick test with a multimeter, two points of solder, and everything was back to normal.
You never know if a task will be easy or difficult without first taking a look.
How To: Fix 1997 Honda Accord DRL Relay
A common problem with the Daytime Running Light (DRL) module in many 90’s Honda vehicles is cold solder joints at the relays in the control module. These develop over time, and cause sometimes intermittent issues with running lights. I encountered this problem, which would usually present itself on mornings with lots of dew, and would fix itself sometime during my commute to work. Rather than pay a mechanic to repair or replace the module, you can do it yourself with some basic tools.
A Google search will reveal many forums and sites with instructions to fix this problem: here are the two links which I consulted prior to performing these repairs.

LCD Monitors
Recently, my “biggest” home project has been acquiring and repairing broken LCD monitors. Most of the time, LCD monitors stop working simply due to some blown capacitors inside, and for me, this is very easy to fix. Because this is a common problem, it has been easy for me to acquire screens like this. In fact, I now have a total of 3 monitors I’ve repaired myself, along with another display that the panel was physically damaged on the top, and another monitor I couldn’t locate the capacitor causing the problem, but that I plan to convert to LED.
The display on the left is a Norcent that was destined for the trash,
the right is a Philips with a band of damage along the top.
