Hey everyone, just had to post what I just finished working on. As you all know I tinker while trying to learn (I have alot to learn) and try to do my best to repair what I can with what I know.
First Project HP f1503: I had previously been given a HP f1503 15" lcd monitor (along with a MAG 15" that I previously fixed). The monitor came with no power supply or vga cable. I was able to pick up a cable from a friend, and the powersupply from the mag is interchangeable with the f1503 so I was able to power it up. Upon turning the monitor on I noted that the picture looked great, however the on screen display would turn on and randomly adjust settings and weird/crazy things. Well after a whole bunch of mis-diagnosing (first thought it was a stuck button on the control panel, then I saw a bad spot in the ribbon cable that goes to the vga unit from the control panel (repaired that), etc.) I finally found the culprit. It was the power button. It's a simple momentary push button power switch that is common on many electronics. Well I didn't want to place an order for just that button if I could help it. It just so happens that my good friend had a Sony CD-Player that had recently died (7 years of wood working use). I keep all electronics so I can salvage what I need, then dispose of. Well I found that the radio had many of the buttons that I needed (I only needed one). Well I de-soldered one from the radio and soldered it in the HP monitor. It's working beautifully. Now I just need to order a secondary power supply so I can use both monitors.

Second Project - Epox 8rda+ - Search for a couple 1500uF 6.3V caps: A couple of months ago I purchased a dead Epox 8rda+ from a member here at ocforums.com. I had a couple of boards to repair at the time so I ordered all the capacitors I needed for the 8rda+ too. Somehow I mis-calculated and was (2) 1500uF 6.3V caps short. Well it's been sitting up in my closet for some time now and while I was tearing apart the pieces from the sony radio, I saw a few 330uF 10V caps. Well I had a spare parts board with a few 1200uF 10V caps. I soldered one of each (1200uf + 330uF = 1530uF 10V) in parallel to each other and connected them to the board. I then powered on the board and noted the voltages in the Bios. It booted without issue. Now I simply need to load up an OS and test it out for stability. I do plan on ordering two normal 1500uF 6.3V caps in the future, but I didn't want to just order 2 caps when shipping is like $6.00 minimum.

Eitherway, just thought I'd share my little projects with you. I've got more in the works, but those haven't started/nor finished yet.
Take care, stay warm, have a Merry Christmas,
