Is This The Hitachi GX01B? You probaly have a capacitor or transistor not within tolerance in your audio circuit. If you would like a service manual and unlimited support for your set to help diagnose it. You can go to the following link they have the46GX01B which is the same chassis as the 43, for 10.99 and they offer free unlimited support with purchase of manual. then if you go back to the site and click on the contact us link and provide your email address they will email your manual to you instead of mailing it. They will also email instructions on how to enter into the free chat sessions. Heres the link. I am one of their support techs.

hello sir,

often this is sound IC fault, if one IC there change it and it will fix the other audio output, as the sound IC have two outputs and one of it doesn't output the audio,

if two sound IC's, it's a must one of it is faulty, you better change both for long run of the audio amplifier

good luck

Kenwood kr 5050 volume stuck on high cant change


These days the circuit of the volume control is controlled by an IC in modern amps. These can go faulty preventing adjustment of the sound by the volume control. The only cure is to find the IC and replace it. You can start in the area where the volume control is located. If it's not mounted direct on the PC board, follow the connections to the board. Hopefully the board might have writing on it to indicate the area where the faulty IC is.

I have a 27" Toshiba television, I'm having problem with the sound. I've changed the sound output but nothing happen. Please help.


Hi
Jennifer Castillo


Here are some possible locations where to look to :
( Since I have no model for your TV or additional details which you have
replaced)

a) switching IC ( these IC switches the TV to Audio Video In)

b) muting circuits ( there could be one )

c) Check the audio out coming from the Jungle IC (also unknown)

d) check the supply lines of the audio IC (could be +12V, typical)

e) Check the headphones out (if available)


If there is an audio Out, connect an external amp to test.

If audio is present , check again for solder joints to main amp.


Use these as a guide in troubleshooting :

Computer Speakers

Your input is the Jungle IC, search on line for datasheet about it.

same with your Switching IC and Audio IC.


On some audio IC, volume control is included on it.

Let us know what you find or needs further assistance.

Whats wrong when my lenovo ideapad speakers start distorting every now and then when sounds are playing? How do i fix this problem or get it to stop?


Try turning down the volume, small speakers in general can't handle a lot, if you still have trouble, the speakers may need to be replaced or the audio output chip. Hook external speakers to see if that will cure it, if no change! replace the ic chip.

Hi,
f61 is a protection code. it means theres is a fault with audio output ic, usually there is dc on one of the speaker output rails, replacing the audio output ic will usually cure this but check speakers and leads for shorts before reconnecting to the unit.

F61 error message


F61 IS THE ERROR CODE FOR A FAULT IN THE AMPLIFIER STAGE OF THE UNIT, if the power fan or supply is okay then THE MOST LIKELY CULPRIT IS THE AUDIO OUTPUT IC, WHICH IS A MULTI LEGGED DEVICE SCREWED TO A PIECE OF METAL USED TO COOL IT, IN PANASONICS ITS PREFIX WILL PROBABLY BE "RSN" BUT IT COULD BE "STK", MAKE A NOTE OF THE NUMBER AND SEARCH ON LINE, DONT FORGET TO CLEAN OFF THE OLD HEATSINK COMPOUND ON THE HEATSINK AND REPLACE WITH FRESH.f61 means theres is a fault with audio output ic, usually there is dc on one of the speaker output rails, replacing the audio output ic will usually cure this but check speakers and leads for shorts before reconnecting to the unit

Hi - and thanks in advance - first time here - have Panasonic model CT-2769SW - audio is either happening (coming thru or mute) or not - inconsistent - any ideas ? Mike :)


Could possibly be a defective audio output IC. I would try re-soldering it first though as that often will cure an intermittant audio problem.
