Sony lbt model hcd-xb6k, distorted sound issue

Sony LBT Model HCD-XB6K 
after selecting phono pressing function button I got the sound output but it is a distorted sound, here note this distorted sound not like humming sound, humming sound is different.
So, can I get any solution to remove this distorted sound?

Hi!
The solution is extremely simple.
Do not use the PHONO input because it is for the turntable.
Its sensitivity is completely different and its characteristics are also different.
Read more: RIAA.
Only one external device can be connected, via the VIDEO input.

If I understand correctly, you need two inputs, but only one can be used.
The solution is a box with a switch that switches the two inputs to one output.
In this way, you have to select an input mechanically, you cannot use the remote control.

A cheap solution. Search for: VSWI2403BK

No,  let me clear all again.
Actually I have two input options at the back side of the sony sound system, one is phono and another is video.
What I have checked that if I select video than I got clear sound without any distortion but sound gets a bit low but it goes ok, but if I select phono than it produces high sound but the problem is the sound is not listenable it distorts    

Please note, here I connect my mobile phone with 3.5 mm jack at the back side of sony sound system. At the back side you will find video and audio input. Selecting phono you need to connect input audio & selecting video you need to connect input video. Video input sound ok but audio input sound really distorts.

I think I could have made you understood enough.What is the solution.

Make a 1:50 resistor  divider and treble enhancement. Reverse RIAA The sensitivity of the Video and Phono input is not the same, your phone simply overdrives it.Phone is not PHONO!

I understand your problem perfectly, and I also described the solution.
The sensitivity of the Video (AUX) input is 250 mV, your phone can output less than that, which is why it sounds normal, but quieter.
The Phono input, on the other hand, is designed for a TURNTABLE, with a sensitivity of 3 mV (not 250) and RIAA characteristics.
This is not suitable for connecting a mobile phone!!!
It should be understood that even though there are two inputs on the back of the device, consider one of them as if it were not there (PHONO).

I have another query, is there any technique to convert CD function of LBT HCD XB6K to USB pen drive function?
Because I have watched few YouTube videos on this issue where easily they convert a CD/DVD player into USB pen drive player so I want convert my LBT HCD XB6K CD function to USB function.
As there is no video of LBT HCD XB6K CD function converted to USB function so I need to know that is this possible to convert LBT HCD XB6K CD function to USB function?

Man!
I couldn't even explain what the PHONO input is for.
Now you want to make a spaceship an old device.
This would require not only hardware but also software knowledge.
Everything is very simple on YouTube, but in reality it is not.
Swimming is also easy, to those who can, but to those who can't swim, it's useless to explain that it's easy.

May I know the actual reason why it is being happened, please help me to explain this.

I have connected Right and Left surround speakers at the back side but no sound I heard.
From here, I have a question that from which function (CD/VIDEO/FM/MD) is the surround option works?

Hi ,
Press "surround" button.It works in all functions. A virtual surround signal goes to the rear speakers. Don't expect a miracle, not a real DTS 5+1 sound!
Otherwise, it is advisable to read the manual of the device! THX!
