i fixed an old lcd monitor. i was rather annoyed that it took several minutes to an hour to "heat up" where you could use it. assuming bulging caps i opened it up and sure enough two 1000uf caps were bulging. i rummaged through all my junk and couldn't find any to replace them with. so i rummaged through my less than junk box and found an old laptop power supply for which i didnt have a use. i gutted it and found some 820uf caps. they were just filtering the power so close enough. put it back together and now it works like a monitor and not something i found at my sister's place and stole.
