Hitachi 42hds52 plasma no audio,but LOUD buzzing comming from rear.any suggestions?please help

Try a different speaker.

It weighs [110 lbs] Gopakumar Gopalan Google

A hard reset rarely helps this sort of issue---look to see if speakers are switched on or off and does the unit work with only a DVD connected to one of the sets of AV jacks on the rear of the set.

Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

I also can not connect my Turtle Beach x11 headphones to the Audio output on this TV - I have tried entering the code above but to no evail - sounds like there is a hidden problem here

This may be too broad to answer because of insufficient explanantion.

Does it BUZZ when not on a channel... an untuned channel or the DVD channel without a DVD playing.

Is it some patrt of the chassis or plastic surround that is vibrating with the volume level.
There are electrical components that will buzz.. (relays ) when they are failing or being overloaded.

So despite being a seemingly simple question, it is more involved than at first glance.

Test some of the things mentioned.. off channel to see if it still buzzes.. put pressure on varios parts of the case to detect loose fitting cover etc.

If you want to risk it open cover and see if you can at least locate the region of the sound on its internal boards. Be carful with this though as it is HIGH Tension Power and is dangerous. Check the simple ones first and then call a service person or someone with electrical knowledge to check the inside.

Thanks for using FIXYA kindly rate my help

sounds like bad audio pcb if buzz comes thru
the speakers,

I would first go into your audio menu and make sure the correct settings haven't been changed, also the variable or fixed output is on fixed.
Does your set have the external surround sound speakers for the rear or are you using an external surround sound audio system?

Hi, the ysus board on the left side looking from the rear of the plasma has blownup, this is a very common problem with 42PD380TA, if the unit is under warranty you are lucky otherwise hitachi charge alot of mooney for service kit.

I have seen 7 hitachi plasmas in 3 months all with the same fault.
HITACHI dont accept there is a production Fault

I have a42hds52a and someone threw something at the screen and broke it. so I am looking for someone who is willing to get rid of thier tv or looking to buy one for parts.
