CRT Television Hum

[Snuffy "Hub Cap" McKinney]

I have a analog TV that is still working fine and no plans to replace it. Over time, it has developed an audio hum - I'm guessing it's 60 Hz. When the picture is dark, the hum is nearly gone. The brighter the picture, the louder it is. I'm guessing some kind of filter on the speaker connections would do it, maybe something as simple as connecting a capacitor circuit.... But, as I ain't the sharpest feller with audio electronics, I thought I better ask the genius pool here!

First I thought was a power cord was near the antenna cable, but that doesn't seem to be the problem.

The key word in all this is "cheap". Anything over $10 is way out of line.

You probably have some bad filter caps,"electrolytic capacitors" that have dried out in the power supply section. You didn't mention if it has a solid state or tube type chassis. 8-)

yep. NO "ripple" down the side of the picture?

If you want the cheapest alternative - just get used to the hum.

THE CHEAPEST REPAIR IS GO PICK UP A USED crt TV....

just last week i had to get rid of a sony projection tv that failed.

ince its illegal to put the tv in the trash, i took it to a local tv dispos al center.

they are taking in 5 bucks per tv, and report most they get are working fin e.

so check craiglist, or ask friends since everyone is buying a new flat scre en lED or LCD tv. they use just a fraction of the electricity the old tube tvs use. saves big $$ on your electric bill:)

much better picture quality, and if you have AC the new tv might be 40 watt s or less, rather than your existing sets 400 watts

Until now.

Thanks taxed & bh. FYI....

because the screen blanks for a while during vertical retrace.

Just get another one. People are giving them away. I sa a perfectly good 19" and 27" go into the trash because no one would take them for free. Check Freecycle or similar.

Personally, I'd never go back to a crt. Love the flatscreen and sharper image. I gave away two 19" sets a couple of years ago.

One of the tuning coils for the sound detector circuit may have drifted out of tune. Get a diagram and an an align,ent tool.

THey use lot more power.

[Tony Hwang]

It's picture brightness related. I'd suspect HV power supply. Maybe cap. is going.

The flat screens use more power???? Could have fooled me. Even my 42 inch plasma draws less current than my old 26 inch CRT. ANd LED TVs draw even less than a plasma

[Tony Hwang]

OP said analog TV. And 60Hz hum.... What flat panel?

I have a flatscreen CRT TV (Sanyo brand). It works too well to replace.

More likely 50 Hz from the mains 50 Hz.

Have you tried praying?

If you knew the answer why post?
