Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Mostly it was the same as the first list you posted (thanks!) but I used the info from the following posts to correct a few.
One of them was a little fatter than the original, but still fit. All the others were identical. The tiny black one was 47uF but I could not read the voltage (the glue covered it).
Parts list, copied from your list and tweaked:
inverter board:
P10294-ND (4)
power board (under heatsink):
P12357-ND...

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
I was one of the first to fix a monitor by replacing capacitors earlier in this thread. I ignored the advice to replace all because I wasn't confident in my soldering skills. I instead replaced only the obviously bad one under the heat sink and two bad ones on the inverter board.
However, about a year later the monitor went dead again.
When I took it apart again, ALL caps under the heat sink were bulging, as well as the remaining two on the inverter board....Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
So, I'm a little bit embarrassed to even post these photos, so you'll just have to realize that I suck at soldering.
I got the caps in the mail today and began the repair job. The one that had the pad ripped off was much more difficult because the solder wouldn't stick down. While I was trying to get it, the soldering iron touched some of the metal channels next to it (in the pictures you can see what a mess it made). Can anyone tell me the purpose of those metal channels? I assumed that...Leave a comment:

Yeah they designed it like some kind of puzzle you'd find at the Sharper Image......Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
So just to be clear, the pad is actually gone but just soldering the new capacitor on there should (hopefully) work without doing anything special?...Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
I found this quote on desoldering:
Except, I'm not sure exactly how to identify pads and traces. I couldn't identify anything directly connected to the solder joint for the cap I removed.
I may not have had enough heat. My soldering iron is, I believe, the 15w [i]Radio Shack[/i] special (believe it or not actually recommended for xbox mod chips because of the lower heat).Re: Westinghouse L2410NM 24" LCD power goes on and off, blue...Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Well the story on the big cap is - I don't have a great soldering iron and I ended up with a mix of heating it, and having to wiggle it loose and then chip off the solder. I may have broken off whatever was there before... What can I do to fix it if it's "burnt off" or broken off as you say? I don't know much about circuit connections.
There are a total of 6 more caps under there, of what looks like 4 different types. I could replace them but I'm worried about the...Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
I don't have anyone better at soldering to help me with this so I took retiredcaps suggestion and bent the heat sink. I am worried I may have cracked something loose while doing so, but I can't see any damage. I got the cap out and took out the caps on the other board. I followed PlainBill's advice (thank you!) on the other thread for ordering from DigiKey and have the following in my basket.

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Sorry, I thought it was suggested in the image posting tutorial you linked to? (for referring to specific pictures)
At least they will be easier to replace. Can you tell me what "bad" might mean in this case, assuming this damage was not recent (and the monitor was working fine before)?
Thanks again for your quick responses....Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Alright, I have some new pictures and I'd like to know how screwed I am.
First of all, I took a closer look at the heat sink, and it looks like there is no way to completely detach it from the transistors before removing the transistors from the board, since one of the screws goes all the way through two of them and is butted up right next to a cap under the heat sink.
.
I'm pretty sure removing all of those transistors and correctly reinstalling them would be...Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Cool, thanks for the help. I will see if I can disassemble the heat sink tonight and try to remove the caps. Will I need to do anything special (like on a processor) for reinstalling the heat sink?
markm75 - Sorry for my ignorance, but what is the inverter board? I did a google search but couldn't figure out what in my specific monitor the inverter board is (but I'm guessing it is the tall boar on the right?) Where did you find this replacement part once you discovered it was bad?Leave a comment:

Re: Westinghouse L2410NM 24" LCD power goes on and off, blue light flickers
Hi,
I'm brand new to the forum but this post is describing exactly the problem I have, with the same model monitor. To the OP, I hope you don't mind me adding my problem to this thread!
Yesterday, I discovered a bad outlet in another room and today I flipped the circuit breaker off to get ready to replace it. It turns out the breaker was labeled wrong and flipped the power to my office off instead. When I turned it back on, the monitor would not come back on. When I plugged...Leave a comment:
