I got a used Barco Data 600 for free some time ago, but the Tubes just won't light up, though
I soldered the "Remote"-Board, which didn't really do anything either.
Apart from the fan, some high-pitch noises and a few internal LED's, it doesn't seem to do anything.
I also tried playing around on / fully disconnecting the Convergence-board, but apart from the high-pitch noise changing to something a bit buzzing (when the hor amp poti goes into low position), no difference.
When pressing the switch near/on the testsignal generator, the high-pitch noise goes away for some time, but that's all.
(Also, one red LED and one green LED light up, as well as three orange ones near the RGB-knobs on the right side. All of the Tube's bases light up a little orange when turned on)
(checked all obvious fuses)
(haven't looked into the black box adjecent to the 35KV Transf.)
Barco data 600 + Barco Rgb-TTL-EGA-Conversion-box thinghy (connected via 4 coax + remote cable) + self-soldered "remote" (checked +17V)
(no VGA-Rs232 cable so far, as i won't build one if none of the tubes light up)
Multimeter, analog Oszi (if necessary), Barco Data 600 Manual, some EE-Student skills
Got the manual from curtpalme.com, will be looking through the service manual soon.
According to http://www.curtpalme.com/Troubleshoo...ps_Barco2.shtm
the red LED might indicate a bad V/H-Card?
Does anyone know wich components are especially damned to fail (apart from capacitors&fuses?)
Do i really need to disconnect all tubes individually according to http://www.curtpalme.com/Troubleshoo...s_Barco3.shtm?
(during power-off, reasonable safety-time for cap-discharge)
