400 hz tone from 32" LCD

Olevia (yeah don't laugh) 400 hz tone through internal speakers no
matter what intput HDMI etc... but not when muted. Tone starts when
you dim the CFLs. Has three settings for ambient room light
compensation. Does not make the tone when the CFLs are at their
brightest setting. And the tone is barely noticable but annoying if
the room is quiet.

Just thought this was odd.

Just out of curiosity... How are you dimming the CFLs? X-10? Or is the
dimming part of the CFLs?

Interesting. Look further down in my thread from the 11th "More strange LCD
distortion ..." Go right to the bottom-but-one post from Meat Plow, and read
what he has to say on this very subject ...

Are you referring to the TV's menu settings?

The menu on my LCD TV shows "DLC on/off", but there is no explanation of
what the setting(s) are for, but now that you've mentioned the topic, I
believe the settings are to compenste for best picture brightness, depending
upon different room light levels.

Changing the selections of DLC on-off changes the display brightness.

On the TV's remote there is a "brightness" button of which you can dim
the TV's backlighting to dark or medium or back to bright. When you
dim the backlight the tone starts. It stops when you set it to bright.
There are no sub menus needed to change the output of the TV's cfls.

Most of them are CCFL's (CC=Cold Cathode). That's very different from

a CFL (C=Compact).

So the C means 'compact' ?

I drop the CC bullshit and just call them cold FL hence CFL.

The point is any seasoned tech would know the difference when I refer
to dimming the CFLs in the set as cold FLs and not compact unless
you're just trying to fuck with me. And there's nothing wrong with
that AFAIC because I do it myself.

I came in late on this, and didn't have the context. I wasn't try to mess
with you.

I've heard them called "cold-cathode fluorescents", but the CFL abbreviation
is commonly used for "compact fluorescent".

PS: There aren't many men who can do that. It's remarkable.
 
Loose core in one or more invertor transformers? Olevea uses some real
sad quality invertor transformers. Set backlight low and hold down
transformer cores one by one to identify who dunnit?

Yeah it's a little confusing but the subject wasn't and I apologize
for not explaining well enough.

The backlighting dimmer causes a 400hz tone when either set to dark or
medium room. When at the bright setting presuming the dimmer is not
functioning the tone is gone.

Might be a problem that could be solved by a firmware via USB upgrade
but the set's manu is Chapter 10 (Syntax-Brillian)

And it's really only a problem when viewing 4:3 content. I like a real
black border on each side and with the backlight cranked up full
that's not possible. What I do is change the aspect to zoom x1 and the
aspect ratio is kept the same although I get a little cropping which
isn't a problem. It isn't even an issue on HD channels as simply
adjusting the gamma and contrast and keeping a small light on in the
room pointing towards the ceiling works very well.
