With my G5 I use a Viewsonic monitor. But often the screen is shaking a lot, and I see a double or triple image of the desk, and I shall switch off the Mac some hours. I dont know if is a screen problem or if is the Mac video card failing? Thanks for your help! Guillermo, designer from Chile

go through the settings

Get a working monitor and turn on the computer. Then swap the monitor with VP201b.

Get a flash light closer to the screen to see whether you can see the desktop screen image. Yes? Then it is your backlight inverter.

Find a Youtube video to show you how to open the cover. Then look for any sign of broken capacitor(s). Replace them and then test your monitor. If all capacitors are okay, it is one of your FUSES. There are 2 tiny surface mount fuses ("FN" type). You can short the two ends to test it before removing them. Often only one of them is broken. Replace it and the monitor shall be okay now.

I would look at the power supply first, this may be the same chassis as VA719B (19"), look for bad caps, see example here: http://s807.photobucket.com/albums/yy352/budm/Viewsonic%20VA912B/

The native resolution for that LCD is 1440x900. If you do not see that resolution in your display properties you can try to update the video driver. If it is still not displayed as an option you may need a newer graphics card. Many newer low end card support this widescreen resolution, so if you need to replace the card you will not need to spend a lot of money.

I have Viewsonic 15" CRT Monitor (model E53)

When power ON, ther is only a colour patch appears on the middle of the screen . I observed some resistors and three transistors in horizontal sections were burnt.
I cannot read the real values of them because they are burnt.
Please kindly can you tell me those real values in that section.

I read through other solutions to this problem because I had the same problem. I checked to make sure electrical cords were properly attached, and vola! problem solved! I had no idea this problem could be fixed just by checking the cord connections. Thanks a million for posting this solution. I had been putting up with the shadowing, streaking for months! You really made my day.

I suspect the screan isnot compatable to the other cpu.change the rete and re boot uour compueter.remember to never fix something that is not broke.

Use the menu button on the monitor itself to adjust for the screen size in DVI mode.

 

On your SVGA adapter, go to your display properties (right click on desktop) click ADVANCED and change the refresh rate to fix the first problem mentioned.

 

 

the capacitors in the monitor give out have to see a technician
