Repairing a dead Dell 3008WFP

Preamble

I purchased off eBay a Dell 3008WFP monitor, a spare screen, control module and power supply unit, along which some spare cables and switches, for around £600 in 2012. It was working fine, although it had obviously been repaired, as the vendor was a Dell repairs department. I noticed that a hot of heat was generated from the rear top vent of the monitor when it was on. Then after a few months, one day, the monitor refused to turn on.

So reluctantly, I started to look for a new fridge on google, and then thought, well let’s test it first. After all, I have a new digital multimeter, as well as the oscilloscope that I had very recently purchased. Plus, if I can reverse engineer a Z80 UART using ASICs, then surely I can repair a god damn ‘fridge..!
