    please, from what shop can i buy the backlight inverter. please

  • skank_bait Oct 11, 2008

    I have same problem as the above. Only with a del E153FP. In any case I know it's the backlight, I've taken it a ppart and I checked the 1000uf cap. it doesn't seem to have any blistering or swelling, looks like a regular new cap. I suppose i could replace it anyway and see if anything changes but thought I should see if there is somewhere else I should look first before going at it with the soldering gun.

Hi...there,

It's seems you need a new backlight inverter. The one you had have a burnt out capicators. You can either replaced yourself or order a new one. Good lucks!

MAG innovision LT-926W 900W problem! After I turn on my computer, the screen immediately begins to flash and then goes black. The power is still on thought and so is my computer. If I take a flash light...


this means your power inverter inside the monitor is dead. This little gizmo lights up the monitor backlight. They dont fail all at once, but slowly die and give problems like you describe, you can order these online for your monitor , or find one on ebay for under 30 dollars, but unfortunately there is no fix, other than replacing the inverter. sorry. Please use the thumbs up rating if you find my answer helpful, albeit bad news. Take care. .

Black screen


It is most likely that the filter capacitors on the power inverter board have failed. I took mine apart and found seven swollen capacitors on the this board, they fail prematurely and seem to be the only thing wrong with the unit. I replaced them and now it is working just fine.

six 470uf 25v electrolytic capacitors and one 220uf 25v Capacitor.

you should not attempt to repair this yourself unless you have some electronics training since there is a shock hazzard involved and also these capacitors will blow apart if they are installed incorrectly (very messy experience).

Sounds like the inverter is dying/died. Take a flashlight and shine it directly or at a large angle at the screen - is the picture still there? If so then the backlight inverter has failed (very common). You can either send it off to get fixed (expensive) OR buy a new inverter and change it yourself (sometimes cheap, sometimes expensive) OR you can repurpose another inverter in your monitor (requires electronic skills and experience but very cheap - http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=ccfl+light+kit )

Your choice

MAG Innovision LT916S monitor problem


Hi this is the way how to examine what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not 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. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. 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!! If anything I can help you with, feel free to let me know.
Thank you,
Tan

MAG Innovision LT1919WDb flat screen goes black


I had the same problem. I contact the manufactuer and they refused to fix it. They said it would cost an additional $100 to have it fixed. I have not even had it a year. I thought products sold in America were suppose to last longer than a year? What has happened to companies standing behind there products. Beware of this monitor!!! DO NOT BUY IT!!! LT1919WDB

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Hi, Try this link http://www.pchub.com/uph/category/43/LCD-Inverter.html In some instances inverters for other brand/model will also work for your Mag. You just have to match the part number. Good luck and kind regards.

My MAG Innovision Monitor went blank, only works if I stay connected to internet


usually this problem is caused by a faulty inverter circuit. transistors might been running too hot or a leaky capacitors also.not an easy task but try looking down for any defects on high voltage sections.
