gateway2000 EV900 died and buzzes
specifically EV900-7000595
The last day it was working it was randomly clicking a lot and the screen would jump when it did it. Now it wont power up but clicks (buzzes) quickly making a racheting sound if I try. As you can tell, I haven't pulled it apart yet or know the correct CRT jargon but I'm good with a multimeter and soldering iron so I'm not afraid to dig in. People mention the fbt a lot with this model as a common failure spot. Somebody please tell me what to check. Thanks Henry |

gateway2000 EV900 died and buzzes
What is the chassis number? Or FCC ID nunber? On a Gateway EV700 with the LG
CA-65 Chassis it would turn on for 20 minutes then turn itself off, and then keep doing it after 5 to 10 minutes (I may be wrong with the times but it was awhile ago I did this monitor). I traced it to a 15 volt line in the SMPS that was going from 0 to 10 volts. I resoulded pin 16 off of the main transformer and that fixed the issue (check the transistors too, sometimes they go bad), I'd go for all the souder joints as well in the SMPS. Make sure to discharge the filter caps. Hope some of this helps you out. I'm not sure if this information would carrie into the EV900 LG Chassis, but it may be some helpful information.
