What would cause the power to the monitor to be unstable?
I got this HX2000 used a few years ago, so I do not know the history of the unit prior to me getting it. That being said it has been working very well so I do not think the monitor is in bad shape internally. However, I set it aside because 900p has largely fallen out of favor and can be difficult to live with. I have pulled it out of storage because I have plans to use it for a few projects I am working on. Anyway, this monitor has 2 different issues:
- Image ghosting
- Inversion problems
For reference, this is how I tested the monitor. What is throwing me off is I don't see typical signs of failing capacitors. While the capacitors look okay visually, it isn't out of the question. It still has the original capacitors as well. From what I see, it looks like a panel or input board problem.
While I am willing to attempt a repair, my budget is limited because of some panel chipping that doesn't affect the monitor to the point of being unusable (with many being surface level) but one of them extends to the entire LCD itself (but is isolated). I'm flexible on this, but I'd really like to stay under what a typical used LCD monitor (in working condition) will probably cost locally (~$20-30, most likely). I'm going to say $10 is my hard limit. The local Radio Shack closed some time back, so I can't buy the capacitors for $1-2 each locally to recap both the power supply and input board anymore.
Here is some photos of the capacitors on the video board and power supply, along with the panel damage
1 year update… Yeah, I didn’t get to this one for some time. Posting for closure.
I tested a small group of capacitors on the monitor (C819/823/820/837/840) and I cannot get a reading. As such, I think this one needs a full recap - if it’s worth trying. Since I sat on it so long (mainly because I paid $1 for it), it isn’t a display I desperately care about. I think I’ll run it until it dies and then move on unless I can think of a case a 1600x900 monitor is worth doing a full recap I don’t know if it’ll fix it or not.
It’s in need of 10 capacitors if I go for a full recap, so in a way it’s not one of those $5 experimental ones. I need to have some assurance. In lieu of a repair, I have provided a capacitor list based on what I found in mine to help others. I have another monitor that’s in perfect shape and have no trouble with getting good used ones (or finding ones with the right fault), so I didn’t really want to address this one. Not to mention getting it for $1 and probably 3-4 years is more then enough for me.
