DOA KDS Radius RAD-5 - 15" LCD Display . . .

[Trash80toHP_Mini]

. . . came from a reputable, concerned seller, picture of it working in test mode in auction, shipped promptly in good faith, but arrived with a problem . . .

. . . it doesn't power up . . .

Symptoms:

Good, Solid Green LED indication on the AC Adapter . . .

DMM says 12.26VDC for 12VDC rated lump-on-a-rope in question . . .

Plug it into receptacle dongled from VGA Connector . . . nice design that . . . but!

LED indicator dims immediately, very noticeably and begins flashing at about 3times/sec . . .

No surprise . . . no powerup of, nor power indication on, this cherry (four mouse rating radius logo'd advert sticker intact, if not perfectly so) LCD for my radius collection!

Let me guess . . . CAPS? :?:

I bought one of these monitors new years ago (AUD $880!! My most expensive monitor of all time), very reliable apart from a "grey screen" fault that comes up from time to time and is fixed by switching the monitor on and off repeatedly. It could apparently be fixed/returned to Radius (and I did read of a repair somewhere online once), but I was happy enough with the monitor so didn't bother, although the faulty did get worse over time.

Due to the monitor's age, I'd suspect caps first.

these KDS monitors were bad for this very same thing.

I had this exact one that did weird stuff like this, and eventually sometimes would power on with lines only.

But sometimes it worked great. I recapped it and checked all the voltages of the DC-DC circuit inside the mainboard and it was fine. still had the same problem.

So i checked out the inverter, i replaced the inverter and never had a problem again.

Strange, but true. inverter failure.

Maybe Sunday I'll rip this thing apart, too busy in the AM and too tired tonight . . . besides, I've got newer toys to play with at this point.

This is the one I really dig on . . .

. . . it interpolates all the fixed freq/resolutions the IIsi and RCPII/IIsi put out to full screen, except Portrait.

Rad-5b Model, too bad it's just a little bit too dark to be PowerBook Gray, but it has the radius logo and it ROCKS!!!!!

Well as long as they stay working, they are GREAT monitors. I will say that.

Speaking of LCDs, I have an old white vintage LCD that came from the trash, i would say a late 90s 15" NEC LCD when they first started coming out.

Works fine. someone threw it away... crazy aint it? heavy sucker for a 15" LCD monitor.

it would fit perfectly with the late beige macs from the G3 era. Just need to hide the NEC logo and stick an apple logo there. ;-)

I actually sold my RAD-5 monitor, was kind of happy to see it go after years of pressing the on/off button repeatedly before a picture was displayed. Like you techknight, I got a white 15" NEC LCD from work, late 90's which matches all my beige 68K/PPC Macs quite nicely
