X2gen mw19u 19'' widescreen monitor going black

When I booted up my pc the monitor would come on for a few seconds then go black. I wouldhave to turn the monitor off then back on. Sometimes I would do this acouple times and it would stay on for good and other times I would gothrough this for a while before it would stay on. Now I can not get it to stay on at all. I just get a second of image then to black. My power light on themonitor stays green when it goes black. If it was the power supplywouldn't that light go out? I did notice yesterday while messing withit that I could see a dark faint image of what was on the screen likethe back light wouldn't stay on or something. I keep hearing about thecapacitors being replaced in these monitors. If this is a good fix Iwould like to know which ones and if they need to be larger or same. Icould use some good ideas with details.

    I have an old dell monitor connected and working with no problems. I checked the DVI cable connections and made sure they were tight and inspected the pins. I tried the x2gen at 800x600 at 59 and 60hz with no change and I booted in safe mode and connected it and same. I disconnected the DVI cable from the pc and turned it on and it did not give me a no cable message it just went black.

    I have the same problem on my 22". Just happened today. If I turn the monitor off and back on, I see the connection message and then everything goes black. Vista sees the monitor and I can set resolution but I can't see anything. It does seem like there might be an image hiding in the darkness. The key is that hitting the menu button on the monitor does not bring up a menu. That says that it isn't the cables or anything like that.



    My monitor was out all morning but just came back to life. I assume that won't be permanent however so would love to know what the fix is when it gets worse and worse.

  • agent_009_87 Nov 23, 2008

    yep, i can't see my menu either, and if you are having the same problem it will probably get worse like mine did.

    For awhile it did seem like temperature made a difference. Where as I was having the most problems when I would first turn it on, especially after a cold night. It seemed that on nights were it was not getting as cold in the house, i did not have as hard of a time getting it to stay on. I was not sure if that was the case or just coincidence.

    My monitor is doing the same thing, whether hooked up to the PC or my laptop.

    I finally fixed it. I took it apart and replaced the 2 - 220 uf 25V and the 1 - 47uF 35V Capacitors on the back light inverter board. I used 220uf 35V for the 220uf 25V Capacitors and 47uF 35V for the 47uF 35V capacitors. It works!

    I fixed my monitor! I took it apart and pulled out the inverter board. I then removed the three capacitors on the board. Two 220uF25V and I believe a 47uF35V. Went to Radio shack and bought two new 220uF35V (I don't believe changing the max voltage made a difference.) and a 47uF35V Capacitors for $5 all together. Soldered them in and turned it on. Victory! It works again. It seems that this monitor is just made with cheap capacitors and they quit working. One note when replacing capacitors. Make sure you have the polarity right. It is marked on the board by a shaded in half of the capacitor outline and on the capacitor but a line on one side with negative symbols(-). I have seen capacitors installed wrong and they blow up, lol.

    Have model MG19VT similar situation. Powers up and on and works for about 1 min. Then lines on screen then fades to black. If I leave unplugged for a day or so the symptoms will repeat. Good guess that the caps are also bad. Opened it up and there are 2 boards. One i consider the main and the other the Power inverter (?) I can only find 2 caps on this model. Does that make sense to anyone? There are other cap markings on the board Eg C11,C12 with bubble shaped components. but not like trad caps. Any thoughts?

X2GEN - MW19U, same problem as described in the other posts. A week ago after a reboot it did not turn on. Pressed the power button, it turned off. Pressed it again after about a minute, all was fine until this morning. Same as before except that this time it does not turn on at all. Checked the power supply with a meter, it is good. Disconnected the video cable, noticed that it would briefly turn on when reconnecting the cable. After 3 or 4 tries with the cable nothing, not even briefly. Checked the video card, it is good. Then connected it to 2nd a computer, it does not turn on. Retrieved the old CRT from garage, both computers work fine with it. I noticed that when it is connected with either computer there is a clicking sound from the right-center side of the back (looking at the back). Could be a relay switch. Unfortunately X2GEn is bankrupt( http://www.x2gen.com/ ), means no recourse, and maybe no parts. Unless it can be fixed for $50 to $75, a new one is the next best option. If any one has any success repairing please post cost and repair details if possible.

Seems like a cold solder problem but also could be a component. The office is colder now and I had this happen when the monitor had been off overnight.I bet if it happens again, I can take it into a toasty room and it will work. It will probably get worse and fail over time, then I will tear into it.

Try your monitor cable connections on both your pc and into your monitor.
Make sure they are TIGHT and level.

Also, it could be your video display card is faulty or your video display drivers are corrupt.

Try setting your desktop to a lower resolution, like 800x600 and see it that helps.

Fortunately or unfortunately I bought two of these monitors. One went completely dead except for the blue and red pilot lights. I took the monitor apart, stand and outside frame. Then it hit me to try the monitor with the power supply from the other X2gen. It works fine. Looks as if the bad power supply isn't putting out enough enough current to energize the relay or whatever is clicking.

Screen goes black but power light stays on


Hello. I had the same problem with my X2gen 19" (model MW19R)monitor. In my case, the monitor would turn off after 20 seconds or so but the blue power light would stay on as well. I had to replace a high voltage capacitor located in the backlight power supply board. There are 4 blue capacitors on the board which are identical and they are marked as 27J 3KV. Fortunately, I only had to replace one of these capacitors ( it was turning a yellowish brownish color ). Hope this helps.

X2GEN MW19U Does Not Power On


You will need a multimeter to check, there is a proteection component that may look like a transistor( but only 2 leads on it) or what might look like a small blue capacitor. also the diodes at the power circut need to be checked. also be sure that solder conections are secure in the power circut

The only way to adjust the tilt on these monitors is to loosen the screws that attach the stand to the monitor. We had to completely remove the stand from the monitor to get to these stand screws.
