Dell Monitor Repair

Somebody gave me an old Dell Monitor 2007FPb which had a problem of switching off by itself. Not wanting to throw it away, I looked up the internet and found that somebody had solved the same problem by replacing a resistor which had changed value.

Whether it was a manufacturing quality control fault of what, I do not know. But when I measured one of the identified resistors which was already installed at the monitor, the resistor was showing a different value from its marking.

Since I did not have a surface mounted resistor, I substituted it with a barrel type resistor. Naturally, I had to drill some holes to install the new resistor. This was a bit tricky because the space between the connections was rather small, and I had to modify some connections with some additional soldered wires.

Anyway, after a bit of work, the problem was solved and the monitor could be used as normal.

Pipe Clamp from a Broken C-Clamp

I had a C-clamp which had broken off. Perhaps it had a flaw or manufacturing defect all along. It only took an extra clamping force to break it at its weakest point. The C-clamp was made of cast iron, and the quality of the cheap clamp was a bit dubious.

Anyway, except for the broken part, all the rest of the c-clamp was in working condition. I was determined to use it rather than to throw it away. What I had in mind was to make a pipe clamp from it. By converting it to a pipe clamp, I could use it to clamp wider items than it could as a c-clamp.

Since the clamping mechanism was made of cast iron, I would not be welding it, because I was not in a position to do cast iron welding. Instead I would drill some holes through it and extend it using bolt and nuts. Some other parts was fabricated out of mild steel parts which I could weld more easily.

The video shows the fabrication of the pipe clamp.
