My X2gen MW19R monitor goes to black while I am

It is most likley the cfl tubes - and - or - the inverter is bad. This will happen sooner or later with all lcd monitors that do not have the L.E.D. back lights. It is very frustrating and timely to replace the items yourself unles you absolutly know what you are doing. You should replace the inverter board with the tubes - it is recomended. I see this problem all the time. Samsung has the L.E.D. backlight and not cfl. The total cost of the DIY [ do it yourself ] will bee about $9.00 per tube [ most use 2 - some have 4 ] and about $15.00 for the inverter board - again - the inverter board could be higher if it uses 4 tubes and prices do not include a hefty shipping fee. Here is a sample link to read and a DIY document with tube sorce.http://store.lcdparts.net/ . Now the prices at this site are expensive - they also cover LCD cfl BACKLIGHT TV's - you can search the web for the proper tube but again - the tubes are like a shop light floresent tube in a really small package and very - very fragile and eay to break. Here is the site and it will explain more for you and guide you along for a reference.http://store.lcdparts.net/ . Once you have figured out a few things - try buying the items elswere . A standard 14" lcd monitor wit 2 tubes and an inverter will cost you a min. of about $50.00 + or - if you shop around. Hope this helped you a little and here is the LCD Backlight Link. http://store.lcdparts.net/ Kevin
