3/30 Has anyone else had a monitor that makes a really high pitched noise?
I changed the refresh from 75 Hz to 85 Hz and it stopped, though.
\_ It most likely means one of your caps is bad. Take it back to
manufacturer for a replacement. If out of warranty open it up
and find out which cap is singing. Get a replacement cap from
Radio Shack or Digikey if it's a rare one. You'll need to be
semi-decent at soldering if the singing cap is on a multilayer
PCB to prevent burning the pad ring off.
BTW, it WILL get worse over time.

\_ Are you giving out advice on how to kill the original poster?
Do not fix it yourself, please.
\_ That's okay, I wasn't planning on fixing it anyway. The monitor
is like 6 or 7 years old now, but I was just wondering. Thanks.
\_ Maybe the noise doesn't stop when you changed from 75Mz to 85Hz,
and it just goes beyond the auditable range which is about 20Hz
- 20kHz.
\_ Is the monitor a trinitron (apeture grill) tube? It could be
"trinitron whine", as the horizontal wires holding the grill
grow loose and the wires resonate with the electron beam.
Noisy but not a physical problem: Give the monitor to
your parents who don't have high frequency hearing anymore. |
