Insignia as monitor

Won't not want.
Hi James,
If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Check the cables, connectors and connections.
If your TV, flatscreen, or monitor is more than 5 years old it is more like to have suffered a
component failure.
Take it to a repair shop.

go to your control panel of your computer (using a different monitor obviously) and change your screen resolution to 640x480, 800x600, 1024x768, or 1440x900. any of those resolutions should work. also go to advanced and make sure it is set at 60 herz.

Get a video card that matches your motherboard and your problems will be fixed

Lets see the cableing..

So you have a mac with a mini-dvi slot, you have a mini-dvi to dvi adapter, and then Dvi to vga adapter which connects to the tv?

The mini-dvi to dvi adapter doesn't have the analog VGA signal your tv needs. If I understood right.

Apple's mini-DVI to DVI-D cable does not carry the analog signal coming from the mini-DVI port on the Apple computer. This means that instead of buying a single mini-DVI cable from Apple and using a cheap DVI-to-VGA adaptor when you need VGA output, you must purchase another mini-DVI cable from Apple.

Heres the dealyo.
Click start button
Click control panel
Click display
Click settings
adjust screen resolution (probably have to go down) until the tv displays your computer
if this did not work, you will have to adjust bit rate from 32 to 16. Fiddle with the settings until the magic happens.
You will not get any sound unless you use an audio jack plugged into t.v.

Im here all week

It's either the VGA cable you are using has a bad pin or the RGB/Color Scheme is set wrong. So try another VGA cable or try the LCDTV on another PC.
