My last video card went out and .....

[Amolao]

my video card went out and took my monitor, very strange...I know of video
card failures but never seen one taking the monitor also...I walk to my
computer and the monitor is dead,after troubleshooting, find out that the
video card is dead and monitor....how can something like this happen???

I know I need to replace them but would like to see what to do so it doesnt
happen again...

video card: Nvidia 128M Video out 3 years old

monitor: Princeton 17 inch 5 years old

Ive known monitors take out video cards. be careful if you replace the card
and try the same monitor

Some older CRTs can be damaged if they receive bad horizontal or
vertical sync signals. They doggedly try to follow the signals and
burn themselves out. Newer monitors are smart and won't pay attention
to signals that are outside the physical limits of the monitor. If
the video card failed and set the sync signals to zero or some super
high value, it might have killed the monitor.

Get a flat-panel monitor to replace it. They don't have circuits that
can be burned out by bad sync, as far as I know (certainly no flyback
transformers or deflection coils or stuff like that).

thanks, but is there any repairs or suggestions? will it be worth it to
repair money wise????

A video card can damage a monitor by driving it at scan rates too high
or too low for the monitor or by switching from one resolution to
another frequently over a prolonged period. But a monitor only 5 years
old won't allow out of range scanning, and you'd notice frequent
changes in resolution well before the monitor would burn out. So my
guess is the monitor finally blew out something in the flyback circuit,
such as an electrolytic capacitor, horizontal output transistor, or the
flyback transformer itself, and only the last one is an expensive fix.
See www.repairfaq.org for more information. Do not take this computer
equipment to an unqualified repair center, such as the typical computer
shop. A monitor specialist or TV tech is far better qualified for
these repairs, but unfortunately he'll charge roughly $90, or not much
less than a new CRT monitor. If you know how to solder and are careful
with high voltage and broken glass and want to attempt this simple
repair yourself, use only high quality capacitors (order from Mouser,
B&D Enterprises, or Digi-key) of the right type (105 Celcius, switching
mode application), and try to avoid NTE substitute transistors (MCM
Electronics and B&D sell exact replacements) because some simply don't
match. The transistor may have to be properly insulated electrically
from its heatsink with a mica washer coated with silicone grease (do
not use Arctic Silver, which is inappropriate for high voltage).

Its the case now in the UK that a 17" Second User CRT can be had for $25 off
the shelve or $18 (£10) if your in the trade.

I curently have about 50 of the things in a lockup which I was paid to take
away.
