Question about Samsung HCJ552W 55" Rear Projection Television

2 Answers

Audio issue Can you help me figure out how to fix the humming that is coming from my speakers. The problem just started. My basic instincts told me to look for a loose audio connection to my stereo. However, all connections look good and the TV speakers humm when the stereo is turned off. I can still listen to the TV but it has to be at a higher volume to drown out the humming. Thanks for your time.

Re: audio issue


Based on your post description:
1. The humming sound is heard with or without external amplifier/speaker;
2. then the source is your TV's audio out. It is also present in your internal speakers which just confirms that it is an internal fault;
3. normally, humming sound in the audio is caused by loose grounding which should not happen since it is internal.  The next likely possible source is a defective power supply (to the audio amp). Often it is a capacitor that dries up, have blisters or have lost its capacitance.
4. In some instances, it could be stray AC component from your signal source such as your cable TV.

You would need to open your TV. It is also important that you be familiar with electronic components and circuitry, soldering and the use of a VOM.  Should this be not comfortable for you, perhaps your best bet is to seek the services of a qualified technician.

Hope this be of some help/idea. Good luck and kind regards.

This may be an issue with the color wheel. My thoughts is that the motor that runs the color wheel is going out. May be time to get it in to a Good TV Repair Service Shop.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv

Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

Do not know if I can solve the issue, but I have a Manual and in reading your issue, it says to press the menu button repeatedly to get to the audi menu. Press + or - to select the audio menu. You can probably see the whole audio menu now and look at the bottom of the menu to make sure the speakers are not off. if they are then press menu until it scrolls to the Speakers on off option and press + or - to turn on. It also says to check the rear of the unit to make sure that the speaker switch is in the internal position. Are you using an S video cable? If so it says you also need to run the red and white audi cables from the tv audio in to the component audio out.
Sorry cant do more, hope it helps..

Humming sound

oVERSEA'S ...thats just wrong... rca parts are availble all over the place. does the sound eminate from the speakers? DOES it go away when you turn it down.. if so two possible outcomes. speakers or something called ssb board which is the main signal or main board in this set. but the audio amp and all audio cuircits are on this board. this board is however technician replaceable only.. authorized technicians have a special computer interface used to transfer settings from old to new board. there are cases where if the humming is coming from the back which might mean flyback or a coil vibrating. is it a lound hum or whine? o buy the way i get most of my rca parts at the shop from union electronics.

Sharp LC-37D6U Aquos audio problem

Your Aquos does not have a separate Audio board, audio circuits are mainly on main pcb. If the guy was able to fix the problem by hooking a surround to the audio out, that means that is a problem with speakers contacts or with one of the outputs.
Borrow a surround or use an amplified speakers set and check if you can fix it with this trick.
To do a real fix, a technician must open the tv, and test all audio connection, and onboard connection to audio outputs to see what is wrong.
If TV is going to work with a surround you will probably get a far better audio quality than the one you get now from TV speakers.

Convergence problems?

While the OP may no longer have this issue, I'll comment on anyone else that may come across this.
In addition to the suggestion of replacing the ICs above by Leadtech, the resistors also should be changed at the same time.  Quite often, even if a single IC or both are replaced and the resistors are not, the issue will re-appear.  There are a few locations selling a kit in the $50 range, so the difference for the additional resistors is minimal.
As for the sound issues, several owners of this and other Hitachi RPTVs in this line have had issues with their sound boards, which seem to be largely a defective product.  Even replacement of these have resulted in the problem re-occurring at a later time.  I would suggest using an external receiver and speakers as it may not be worth the time and money to repair this problem.  -TD
