Testimonial: "Hi Claude, Thanks for your reply. However, I'm not clear as to what to do still. The capacitors on the power supply board dont show sign of bulging. Can you help clerify what the solution should be? Thanks"

    Could you jump the capacitor with an identical one?

    Would you recommend replacing the entire power supply rather than fiddling with individual capacitors? More important, is the power supply board the solution? Thanks

What can I do to stop by iMac G5 LCD screen from being pixelated and getting dark blue and pink horizontal lines across it?

This very likely a failure in the LCD screen. If you are seeing thin or wide bands, vertical or horizontal across the screen, then you will need to have the unit serviced to repair or replace the screen. If the unit has been dropped or struck (hard) it is possible the connector cable for the screen has come loose, but this is not usually the issue. If the unit is still under warranty, get it serviced. If it is not under warranty, there are several good web sites that provide Do-It-Your-Self instructional videos as well as parts, both new and refurbished and used. If you google your specific model and "screen replacement", you will see a number of results appear that would be of use.

How do I correct pink and green bands accross HP-R4252 Plasma TV

First of all try, changing the input device to some other and see whether you see the same problem. Then connect your present input to a different TV and see. If you feel the input is ok, and it is a problem in the display, this is a case to be handled by a qualified service technician.

Tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Red screen, horizontal lines, 2'' black vertical bars both sides

it looks to me that you are not a technician becouse you are measuring at the wrong places risking a hazard shock if you have a little experience get the service manual and check your power supply and the h v capacitors near the horizontal output if not please take it to your service center

Pink and green patches on screen

The thin red, green, or yellow/brown line you see running through your LCD is a line of dead pixels. To fix this problem, you will have to get your monitor serviced or, if the monitor is new, replaced.

Pink Screen on Vizio 37 inch with HDMI Connection

Hi,
I work as a contract technician for Vizio, and I can tell you from experience that replacing motherboard is one of the only solutions to this problem. The other solution if under warranty is to replace it. If you experience red, blue, or green pixels where dark shades (like nose, eyes, clothes, etc), call Vizio and accept nothing less than a full replacement! I have had situations where I replaced motherboard and within 2-3 hours the pixels return. Hope this helps.
