Why will my computer not boot and show video?

My mac mini simply will not boot.

When I hit the power button it comes on "fans spin slowly and solid white LED" but nothing comes on the display plus there is no chime.

First step, I tried another display. Fail - Same result.

I then tried pressing and holding the power button, I then get about 3 seconds of a fast blinking led then it stays solid but still no video or sound.

I then took it apart and removed everything but the CPU. "CD drive, HD, Memory" The LED blinks twice fast but then just on/off, on/off. After I insert the memory it goes back to solid white.

I tried different known working memory. First filling up both slots, then just each individually. Still the same result.

I reset the PMU/SMC. Also by hitting the small button on the logicboard only once. Still the same result.

I tired burning the Firmware Restore CD 1.3 and using it. However the instructions call for 1 fast blink 3 slow blinks then fast blinks when holding down the power button. However, as stated previously, it only blinks very fast for about 3 seconds. Needless to say the disc didnt boot.

When I had it apart, I check the logicboard for popped caps, but didn't see any. Could it be the GPU?

I really need to get the computer working as I cant afford a new logic board "I'm afraid this might be the issue" nor a new computer...

Why are the logic boards so dang expensive!

attached is a youtube video showing what its doing...

Ok I have a few questions so I can understand the POST process better.

When the computer is powered on and I hear a chime then that means the computer passed POST, right?

If the mac doesn't make post error sounds then the light should flicker +1 to accommodate the missing sound?

Is it normal when ...

I have everything removed "including cpu" I have a solid white light.

If I insert the CPU, but still have no RAM then I get a steady blinking light/

If I have both ram and cpu installed im back to a solid white light.

if everything is connected and I hold down the power button while booting up I get about 3 seconds of a fast blinking LED.

It never makes a "speaker" sound despite what I do.

Your best bet is that this is a RAM problem. Either a stick has gone bad or a slot. Try one stick at a time in each slot.

These are the beep and flash codes:

1 beep = No RAM installed/detected

2 beeps = Incompatible RAM type installed (for example, EDO)

3 beeps = No RAM banks passed memory testing

4 beeps = Bad checksum for the remainder of the boot ROM

5 beeps = Bad checksum for the ROM boot block

when the light flashes - you must add 1 flashing for the corresponding code (like 1 beep equals 2 flashes = no ram installed and so on)
