Dell 1702FP is a really neat LCD monitor. Here are some specs:
Contrast Ratio: 350:1
Aspect Ratio: 5:4 (Regular)
Max. Resolution: 1280 x 1024
The bad thing: it has a very common problem: it fails to power on after a certain period. The marketplace is full of faulty Dell LCDs.
The good thing: the fix is very easy. All you need is to replace a capacitor, and voila! it works again. The cost of capacitors won't exceed a dollar. Considering that you have the tools handy, then your only cost is acquiring a faulty monitor...
TOOLS NEEDED: Philips screwdriver (no. 0 and 1), pliers, soldering iron, solder, utility knife...
PARTS NEEDED: Electrolytic capacitors - 2 pieces 10uF 16V (critical ones), 6 pieces 22uF 16V, 4 pieces 100uF 25V
Step 1: Go and find a faulty Dell 1702FP!
Well, not a very easy and quick job, but still easier than you think! If you are not willing to pay for it (like me) go and check out IT services at your school, look at recycling centers, curbside garbage bins, etc. I am sure you'll come across one. I found two only at my department! If I check the whole university I am sure I'll find dozens more...
If you are willing to pay some for it, go check ebay! You can get something ranging from $10 to $40 including shipping. Make sure you are getting the power brick, too. Otherwise you'll shell out another $15-$30 for it.
The fault description you are looking for is "blinking LEDs" and "no picture". Sharp ears can hear a soft clicking sound coming from inside the monitor, too. Make sure that LCD has no cracks, visually it looks fine, etc.
If you are overwhelmed with search results, you can narrow it with tags like "AS-IS", "BROKEN", "FOR REPAIR", "FOR PARTS" or "FAULTY"... Also, check the ones with very low bidding price/history. There are not many people looking for faulty LCDs, yet. :-)
