View Full Version : Why does my TV remote beep?

I have a new TV with a new remote that's fully backlit. When I press any button on the remote, while the backlight is on (about 5 seconds), the remote emits a high-pitched beep. Does something from the light cause the beep? It's highly annoying. Do all backlit remotes do this? Is there any way I can make it stop, short of throwing it against a wall and breaking it entirely?

What kind of TV is it? I've had plenty of backlit remotes - none of them ever beeped.

It's a Toshiba 34HFX84.

It squeals when the backlight is on? If so, I'm afraid there's no cure other than replacement.

A bit of circuitry called a DC-DC converter is likely the culprit - it takes the 3 or 6 volts from the remote's batteries and boosts it to whatever's needed to power the light. These things do have a way of squealing, sometimes.

FWIW - My Palm makes an annoying squeal in the same manner and it's described as a characteristic of the technology and not covered by warranty.
