TV that only has headphone out to receiver/amp

[JayPoorJay]

Hello All... Grateful for this site!

I just repaired a 70inch Sharp flat screen I found on the curb in NYC (there are 1000s) thanks to the good folks on this site

I have a question about an audio signal from a TV that only has a headphone jack as a audio output source. I have it hooked up now with a headphone style adapter that converts the headphone plug to an RCA. I plug this into my PHONO input on the receiver. To play it this way I need to turn volume waaaay down on TV and volume up higher than I think I should on the receiver. I get undertone hissy sound, blunt sounds from speakers when I turn the thing off and on,,, it's not good - I'm afraid of damage to the receiver due to too much power from the headphone output to an input that is supposed to be minimally amped, all that.

QUESTION: Is there a simple device I can purchase that can be put between the headphone jack and the receiver that will reduce the signal strength going into the receiver?

what model of tv is it? Why are you using a phono input and not a regular "aux type" input. Depending on the receiver, the phono input has certain impedance requirements and resulting preamp gains before heading towards the main amp section.

Hey Man. Thanks.

When I use the AUX ports on the back of the Sony receiver I get NO sound. It's strange. I thought that would be my inlet... It's a "INSIGNA" TV. Cheap, but it's working for me...

do not plug into phono as that's low level input for playing records . plug into aux or whatever other input it has .

you likely turned down the tv volume too low for the "aux" rca inputs to provide proper signal. try turning the tv volume back up to near max. It should work albeit would be not the greatest sound because there will still be a mismatch of expected impedance but should be usable. As posted, the phono input for most amps will usually not be a good input for any other signal type than a record player due to design intent (impedance, equalization and gain).

without the actual model number of the set, it hard to give any other possible solution.

Thank you! You nailed it, and I feel dumb...

I swapped around the wires, turned the tv volume up to near max,,, low and behold - there was sound! A much much better (no more hiss - or clunk when I turn the TV off with eceiver on) than what it was, tho it still ain't right...as you say, for the reasons you say. Thanks much.
