Hi all,
New here, still have to update my profile. Quick version - I'm Kyle, college student, have been soldering for years. Recently acquired a broken 19" LCD TV for $10, recapped it, and now it's perfect. This led me to go get about 12 more LCDs, from 17" displays up to a 32" LCD HDTV. Most are obvious bad caps, a couple have me stumped (of course, the newer/nicer units )
I have a Dell 19" widescreen LCD, from about 2007. No visibly bad caps. When plugged in, I hear a faint :tick: :tick: :tick:. Maybe its a faint "click". Anyway, it sounds like it is coming from the big cap in the mains voltage section of the board. It's a CapXon (i know) 120uf 450v(L) cap. The clicking remains for about 5 seconds after the plug is removed.
Should I just recap the power supply based on the fact that it is composed of CapXon, TAICON, and no-name caps? Or, does it sound like something else could be fried?
Thanks for any and all assistance. I should be able to post photos if needed, just don't have a camera with me right now.
