I have a Rainbow 100A monitor problem (I think). Input from anyone would be greatly appreciated. When the system is powered on everything seems to check out, except the monitor will not work (no display). All of my error lights on the system board are off and it seems to respond correctly to keyboard sequences (e.g. dir, chkdsk, etc...) as far as I can tell without a screen. Does this seem like a monitor replacement situation? Are there any workable alternatives besides the $195 swap-out with DEC? Again, any info at all would be greatly appreciated. Thanks, Frank Gossett Bnet: uahfxg01@uahvax1 Inet: uahfxg01@asnuah.asn.net P.S. I've disconnected and re-connected the monitor cables just to see if it may be corrosion related...no luck.

You have of course tried turning up the brightness and contrast controls
on the rear of the unit, no? There are also some pots inside, one
of which (don't know which it is) can be tweaked to turn up the brightness.
If that fails, your best course is to buy a new one from DEC. They
are currently on sale @ $75 for white phosphor and $100 for green or
amber.

>I have a Rainbow 100A monitor problem (I think). Input from anyone >would be greatly appreciated. In the past, I've seen a lot of problems with DEC monitors, particularly with VT1XX's, but also with my Rainbows. I havn't had the time to track down the Rainbow problem, but more often than not the problem with the VT1XX's were the high-voltage power supply and/or the flyback coil. (The latter is part of the power supply). You might be able to take it to a TV or computer repair place and have the work done at a much lower cost that taking it to DEC. -HWM ---------- Henry W.

>>I have a Rainbow 100A monitor problem (I think). Input from anyone >>would be greatly appreciated. A few months ago I had a problem with my monitor - the display became unstable and distorted. A technician in my lab tracked it down - it was fixed by adjusting an internal pot. Last week the monitor finally died. I don't think it's anything too serious, so I'll take it to a repair shop to get it checked out. ...Rick
