Strange shrunken capacitor(?)
I have an old Gateway EV700 monitor which shuts down after a few minutes of
use. It sometimes sort of flashes the screen as if maybe it's trying to start back up, but is never able to on its own. It will come back on for a few seconds if power cycled, but will then shut down again. After it's been off for awhile it will come back on and last a few more minutes, but then exhibits the above problems again. When it shuts down, it has a sort of rainbow swirl pattern in the center of the screen. I opened it up to see if there was anything obviously wrong, and saw what looks like a capacitor which has been twisted and shrunken, but I'll admit that my knowledge is limited enough that it could be something else entirely. Here are some pictures. The white goo on the side is just glue, it didn't come from inside the object. I didn't see any obvious signs of leakage or damage, but this thing certainly looks unnatural. http://tinyurl.com/2ysl3r http://tinyurl.com/ytxby8 http://tinyurl.com/2gbe8v Any idea what this is, if it's bad, and if replacing it might solve the shutdown problem? Thanks for any info anyone can provide. |
