eMac Monitor Problem

Hi,

It sounds heat related, have you blown the dust out of it lately?

As a test, Safe Boot from the HD, (holding Shift key down at bootup), Does the Video last longer that way?

What all can be transfered? The whole logic board, RAM, HD, Superdrive? Any Combination?

Depending on the 2nd version, I doubt the logic Board which contains the Video card, (and likely your problem), will fit from the USB2 models to the earlier ones without a lot of work.

If the CPUs are in ZIF sockets they can be swapped, Hard Drive & CD/DVD should be fine, RAM depends on models.

Sadly, I've lately seen the top of the line eMacs, the 1.42GHz/USB2 model going for $50 or less on eBay.

Shipping probably doubles that!

Indeed, but if you can find one close enough, you might be able to pick it up yourself.

OK... Good Luck! 🙂

Blowing the dust out generally requires a good Air Compressor, or $200 worth of canned air.

The eMac's monitor stayed on for weeks with the target disk screen in that setup.

Yes, that mode like Safe Mode doesn't use Quartz or all of the VRAM if I recall rightly, & a simple video driver.

No temp think to reset, sorry.

The best gadget for stubborn dust deposits is a pastry brush. Make sure you get one with a wodden handle and natural bristles to avoid static isses. I have close to a dozen in various sizes and shapes in my computer kit.

Be sure you know the exact version of the eMac you have before looking up take-down instructions. There are two variants: those with USB 1.1 logic boards and 700Mhz, 800Mhz, and 1Ghz processors; and those with a USB 2.0 logic board. The latter are mostl y1.25 and 1.42G processors but there are some uncataloged "edu-only" eMacs with the USB2 board but only a 1Ghz processor. That;s the version that leads be to this caution.

The case take-apart is slightly different between the original 4,4 eMacs and the later 6,4 versions. Some people have broken the power switch while trying to use the older instructions to take about a newer eMac.

The 4,4 and 6,4 codes come from System Profiler (Apple menu > About this Mac and then click the "More Info..." button). It the second line of the opening Profiler screen. A code of 4,4 on your computer means it's USB 1.1 and a code of 6,4 means it;s the later USB 2.0 version.
