Question about Computers & Internet
I have a VG2245WM Monitor it recieves power and the indicator light goes from orange to blue which indicates that there is a signal from the PC, but its weird the screen has funky colors and everything isn't clear, and everything seems very red and dark, I tried playing around with monitor settings but you can't even read what is in the menu, there is a blue box which is usually the menu, but it doesn't show what is what....I took it apart to check out the power board and see if it had the same problem as my other viewsonic vg2021m which had bad caps which were blugging out, but apparently the caps on this one looks fine...Can anyone help? Is it the back light our the video board? oh ya I turned on the monitor with the back cover off and it seems like the backlights are on and its bright...odd very odd????
The caps can be bad with high ESR with no sign of bulging/leaking: http://s807.photobucket.com/albums/yy352/budm/Bad%20capacitors/
If you get pinkish glow and dimmed screen, it can be bad lamps: http://s807.photobucket.com/albums/yy352/budm/Bad%20backlight%20lamp/
I will still suspect the caps first. Check to see if you do have about 12~18vdc feeding the inverter circuits.
