Question about Hanns.G Corporation JW-199DPB 19" LCD Monitor

1 Answer

Monitor problem I have a Hanns-G HN199D 19" LCD monitor, have had it for about three years now, and never had a single problem yet. I've always turned my monitor off when I sleep at night, or go out somewhere. But just recently, one morning I got up and turned my monitor on. And the green power light would flash but the monitor would never come on. It took it about 10 minutes to finally come back on. It's done it three times, and I've kept the monitor turned on now to prevent it from not coming back on. It's not in sleep mode, because sleep mode is a steady amber light. Green is power on, and my computer runs normally. I even hooked the monitor up to another computer and it did the same thing. Took it a while to come back on. I searched and can't find any fixes for this model monitor. Does anyone know why it's doing this and how to fix it short of getting a new monitor?

    My problem is similar, except sometimes it takes hours to turn on. If you look closely, you can see glimpses of light on the screen, like it is attempting to turn on with each flash of the green button. I'm not an electronics expert but this problem seems like a bad relay, when it finally clicks in aholds, everything is fine.

Hi, I used to repair a monitor from Dell. You might have to check what wrong with your monitor when it went back by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem like broken lamps and it is very easy to replace. But the most important part is you need to know how to teardown the screen. . If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.


Hope this help you to examine your monitor. If there is anything I can help you with, feel free to let me know.
Thank you,

Honestly it sounds like something is going bad in the monitor (my guess would be either the main power supply or the backlight power supply) and you would either need to know electronics or know someone who knows about repairing electronics to fix the problem without replacing the monitor.
