Re: Help me fix my LCD monitor
Unfortunately, I didn't have any knowledge to judge whether the two solder balls were meant to be joined or not. I just supposed that it should be so since I remembered that it had been so.
Yesterady I separated the two points by removing some solder in the middle. But the result was the same, the coil of line filter sparked again and the fuse blew. I wasn't sure if it was caused by broken line filter but I thought maybe the jointed solder wasn't the cause....

Re: Help me fix my LCD monitor
Thank you for your comment, momaka. Yeah I should have stopped when there was a problem. I was imprudent.
So I borrowed two books from library yesterday. They are about basic electronics. I'm going to read them and grasp the principles of this SMPS.Leave a comment:

Re: Help me fix my LCD monitor
Oh my got. I burned the 'line filter.' Still I can smell the chemical smoke in my room.
Here is what went. I noticed that one solder ball(of a capacitor that I was going to change) extended to another(of a resistor) making it look like a solder strait. But I didn't care since it had been as it was, and I resoldered as it was. I was testing the monitor everytime I changed one cap, and I don't know if it was right after I resoldered the one linked to resistor, the fuse cut off. I laid a solder string instead of the broken fuse recklessly....Leave a comment:

Re: Help me fix my LCD monitor
I thought I could remove the sinks first and then touch the caps. I don't think working under the sinks will do.
[QUOTE=Radio Fox] Anyway, as already recommended by others, replacing all the electrolytic capacitors will, hopefuly, cure the problem.

Sure, I see. Thanks for your kind explanation.
Yeah, maybe I should practice with another material before I succeed on the real trial.Re: Help me fix my LCD monitor

Re: Help me fix my LCD monitor
Thank you, Radio Fox. Right you are that I'm using it on a resistance range. Do you mean that by doing so I can't know if the cap is shorted or broken since caps with low capacity doesn't react to that kind of testing?Leave a comment:

Thank you Plain Bill, momaka and Agent24. I'll do so and let you know the result soon again.

Re: Help me fix my LCD monitor
I really appreciate, PlainBill. Thanks to your advice, I could learn more.
To answer your questions, the caps' brand is Sam Young. And there are total 5 caps under two heat sink, 3 in one and 2 in another.
So, then the ceramic cap doesn't have to be replaced even though it doesn't react to my tester? Is there other ways I can tell whether a certain cap(ceramic or electrolytic) is alive or not with an alalogue tester?
And there are chip caps on another board. I was thinking of replacing them also. Is it...Leave a comment:

My LCD broke down and I decided to do something on it myself. The problem is that I have no idea how to fix it. So I searched on the internet and luckily found this helpful forum. I believe there is somebody who knows well about this matter.
Symptom : 1. At the first stage, the monitor's power light LED kept changing from orange to green and then green to orange while my computer was in 'sleep mode'. It showed me a color adjustment screen(stripes of Red, Cyan and Green) when the LED turned green. Normally... -
