Why do I have crackling and hiss in one channel


If it is making noise as you describe with nothing plugged into the channel and without moving the controls, it needs to go to the shop. You should contact Peavey to discuss the problem. Here is a link to their support page-

I have an old late 70s Peavey PA-400 powered mixer. It's a workhorse that suddenly started doing the following: As soon as you turn it on - both speakers hum pretty loudly, and the back of the PA...


As these units get old, the solder joints can start to fail. Also, come of the components are getting tired. If you have no electronics experience, bring this to a servicer. I typically overhaul these units for about $100 plus parts. In most cases, the parts costis less than $20. These are solid units and you can probably get another 30 years out of it.

Part of the overhaul should be reseating all of the output transistors and replacing all of the heatsink compound as well as cleaning out all of the pots and switches.

Keep us posted.

Have a phiips tv had it in storage for over a year turned it on an the screen working perfectly but there a hising noise coming from the back of it do no what it is... Its a big bk tv not flat screen box...


hissing noise will be from high voltage regulator, i would suggest to do following:

1. switch tv off
2. remove plug from the wall
3. using air blower (compressor attachment - not leaf one!) blow the dust, especially from high voltage box section
4. connect the tv and switch on

if tv still issue hissing noise - follow 1 and 2 then:
3. remove back cover
4. use air blower again...
5. re-install back cover
6. reconnect tv and switch on

if hissing noise persist - check for blown capacitors on high voltage, replace if necessary, they have nasty tendency to pop if they are too long in storage, especially if tehy were overheated or frozen.

hope this will help you solve the problem, do not forget to vote...

I have a Peavey PV 115 Speaker...The horn works and the fuses are good ..The wiring looks and feel tight BUT the 15" speaker will not work...Any ideas ???


Check the resistance across the woofer connection points. Using an ohmmeter, you should se around 6 to 8 ohms. If there is no continuity, you have a blown speaker.

My speakers snap, crakle, pop like Rice Krispies.


make sure the power to the TV and the receiver are not on the same ground. Move the TV power cord to another outlet, or get a power conditioner instead of a power strip.

All mechanical switches such as sliders and pots will get noisy after time. They get mildew and tarnish on contacts. Get a can of WD-40 and spray all switches and pots inside. You can do this by inserting the straw nozzle into slider switch slot or pot space where wires and attach. Spray briefly (short burst), then work control to both extremes of travel.

PEAVEY djs4 speaker QUESTION


If a speaker is "blown", there is normally an open-circuit in the voice coil, therefore it emits no sound at all. Can't discount a loose wire, but blown HF drivers are very common.
