There are (4) caps that needs to be replaced (3) 440uf 25v and (1) 330uf 25v. in the lamp driver circuitry. They should be obvious which ones because the tops will be popped up.

From what I have heard the isn't a great monitor and most say stay away. Sorry for the advice. There is one thing I would try, to increase the Hertz from 60 to at least 70...here is how: right click in an open area on your desktop...a box opens...->PROPERTIES->SETTINGS TAB->ADVANCE->MONITOR TAB-MONITOR SETTINGS there you'll see a drop down arrow->click on it a select 70HERTz ->APPLY-> OK...just for good measure, reboot...that may help..if not try the link below for more help Good luck...

My monitor is flickering


Flickering on the screen can be caused by defective hardware in the computer or by improperly installed software monitor may flicker and goes into rolling state due to dust, overheating after a long continuous usage,loose circuitry or due to some electromagnetic interference with other like tv , UPS, large speaker systems etc.


FIX :

1.Try Re-installing your Video driver

2 If it is possible, connect a different monitor to the computer. If the flickering disappears, it is a fair indication that the monitor is defective, otherwise go to the next step.

3. Set up the computer and the monitor on a different place in your house. If the flickering disappears now, it is most likely an interference caused by something in the original location. Check for devices which can cause interference.

4. If the flickering persists, check the setup of your system. If available in the setup, make sure that the option Monitor Type is configured as Colour Non-Interlaced.


If you don't think any above possible reasons for the rolling or flickering state of your monitor then we recommend you to get your monitor checked by the monitor company at their respective service cente

Monitor goes blank


Try restarting the computer in Safe Mode and then check. In case it flickers in Safe Mode too, then the LCD screen might be damaged and you might need to replace it.

No picture on monitor


The Q7 has a tendency to burn up transistors and a high voltage capacitor on the one half of the inverter board which is part of the power board.
I have repaired 1/2 dozen of these with that problem.
Only way to tell for sure would be to open it up and look at it.
If you can do that and send me a picture to bammbamm@ptd.net, I may be able to confirm this.
The other possible problem could be a bad bulb, but since it is fairly new ? that is probably not the issue.
