Question about Gateway HD2200 LCD Monitor
Turns on for 2 seconds then is black no respond was fine last nite
was also flashing on off
The problem with the monitor is the power inverter board. I took my monitor apart and tested all the power outputs. The ones going to the main board where ok but the ones going to the backlight where different. I changed the three capacitors on the power board that where located between the two heat sinks I think it was the 1000uf and the two 470uf. They looked ok but when i tested them they where off. Next on the opposite side of the board with all the little componites there are a few dry joins that you have to resolder. If you cant find then you can just resolder the whole back board it should only take 30min. If you have no idea what i am talking about i would not sugest taking the monitor apart.

I have the same monitor and have dealt with this for some time now. I think it may be a problem with the monitor not letting your tower know to look for the correct video source. The problem became much worse when I started using an HDMI cable. I think it may actually be my p.c., because when I shut down my tower and pull the power plug from the back of the p.c. for 10 seconds or so, it fixes it every time.

Timezone88, hope you get this since it is an old posting. I just replaced all the caps on my power inverter board. I have 10v comming off the board but do NOT have any 5v. Any idea what component creates the 5v? Do you have a schematic for this board? thanks

When you say it was flashing on and off do you mean the power or the picture? If the picture it could be a fault with one or both of the rectifiers otherwise maybe something wrong on the power supply. Sorry my guess could not be a bit more accurate, if you can please write a little bit more information. Good luck.
