Re: Hanns-G HG281D, LCD Monitor no power
Here are some pictures of the boards. Also, would this suffice to repair the logic board: [url]http://www.ebay.com/itm/Hanns-G-HG281D-Rev2-TV-LCD-Monitor-CAPACITOR-Repair-Kit-w-Solder-Iron-/151295736229?pt=LH_DefaultDomain_0&hash=item2339edb9a5[/url] (the new soldering iron would be nice, my current iron is a Weller SP23L). Suggestions for an iron/caps/solder etc would be greatly appreciated!
The scratches are from my iron slipping while I was attempting to remove the old caps.Re: Hanns-G HG281D, LCD Monitor no power

Re: Hanns-G HG281D, LCD Monitor no power
I believe one of the two caps replaced may have been in backwards, that is correct.
Thanks for the helpful video, I learned a few things from it. I know the tip I have now is not ideal for this application, I will be purchasing some new tips and an additional cap kit for both boards next week. What kind of solder would be best for this? Lead-free w/ flux core?...Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Thanks for the thorough reply. I have a multimeter but not a ESR meter. My soldering iron has a more Flathead like tip on it, I cannot locate my other tips. I will take some pictures of my tools/solder/PSU/Logic Board and get them posted ASAP.
I had a hell of a time trying to get the old caps off, It took 10-15 minutes before my iron was hot enough to get the solder to melt. I believe I may have messed up a pad on the c80 cap, I will take detailed pictures of these as well....Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Re-capped it with NEW caps, correct polarity this time, still no power. My soldering iron isn't the best, I may have heated the board to much during the soldering/de-soldering process, I noticed the solder was having a hard time sticking to the cap's and the board.
Maybe I should purchase a new board?
I know with a new board comes the same crummy caps, but it may be better to re-cap a new board then attempt to re-cap this one again?...Last edited by davisgarth09; 07-31-2014, 08:50 PM.Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
All cables have been re-connected about 4 times now. Maybe the polarity is incorrect? After the re-cap, the first power on attempt showed a blue then orange light (no picture). The second attempt and any following attempts show no lights....Leave a comment:

Re: Hanns-G HG281D, LCD Monitor no power
Hello All! Just got my hands a used Hanns G HG281D. The screen will sometimes stayed powered on for ~1+ hours, or only a few minutes. The main issue is the screen "flickers" and has these horizontal squiggly lines. When the screen goes black, the power light would stay blue. I replaced the c83 and c80 caps, but now the screen will not power on at all, no lights - nothing! I've even tried re-soldering the caps. Did I fry something?Leave a comment:
