7100 AV board dead ?

HI
I have a 7100/80 AV with 16 mb ram running system 7.5. I t had been acting very slow for some time - read slower than a mac plus...especially for screen refreshes (a very slow mo version). Running Norton reported reasonable speeds for all things except for video which clocked in at 0.25% of a Quadra 610. Zapped Pram, ran a virus check etc to no avail
Finally, yesterday the video went out altogether. The monitor green light comes on and then goes out. The rest of teh computer appears to boot up and go through its motions. Is it likely that the AV board has died. There seems to be another monitor port on the computer, but the connector is not the kind that the monitor cable goes to. ANy ideas on how to access that port or connect to it. My books are lost. Also, any point in reformatting my hard disk and putting a new system on ?
Thanks

Your video card may be dead, your battery may be dead, or both. It is unlikely that the motherborad is dead. You would hear nothing at startup or the startup chime would be a series of discordant notes.


First step...unplug the video cable at both ends and re-seat the cable. You may have a bad connection.

If that does not work, try pushing the power nipple to turn on the machine and hold down the shift key to turn extensions off. After a minute or so (completed boot cycle), push the Control, Command (open Apple) and Power keys simultaneously. This will force restart the machine. If the monitor gets sync, check the date on your machine. If the year is 1956, your battery is dead.

The other video port (HDI-45...45 pins) requires an adapter cable before you can use it with your current monitor. Special monitors (AppleVision, ColorSync, etc.) were designed for use with the HDI-45 configuration. The keyboard and mouse (ADB) plug directly into these Apple Monitors. The adapter has ADB and sound plugs dangling off of it. Once you have the adapter, you can plug your current monitor into it. Plugging in the Sound and ADB off of the connector sends the ADB and Sound info to the monitor. If your monitor does not support these features, obviously you won't plug them in.

It would be a good idea to have the HDI-45 cable (or cable adapter - pronounced aach dee eye) even though they are a bit pricey. Maybe your local retailer has one in stock.
