Question about Harman Kardon AVR 500 Receiver

Harman Kardon AVR 500: randomly accelerates volume levels.

Sirs: Is the broke part #J32612050102? A digital volume control chip? A bad DTS? How much to fix? Can I fix myself; if so, where can I buy parts? Thanks. Chuck.

The problem is with the actual eltromechanical element on the volume control, my avr 300 does this as well and I'll let you know the secret to avoiding it. There are small indents on the volume control as you turn it, if you leave it half way between indents, it will periodically start reading volume changes, if you're lucky it will go down, if you're unlucky by the time you've noticed it act up your speakers are blown. When you change the volume, make sure the control rests in an indent and the problem will never crop up again. A simple solution if you're the only one that uses the receiver.

You need to reset the microprocessor.

Push the main power button to "off" then push and hold down the dolby pro logic and am/fm button simultaneously while pushing the power button back "on" ...should solve the problem.
Keep in mind all settings will reset to factory settings- you will have to reset your delay and speaker surround levels-also your input selections.

Hi i have problems with SOny STR-DE958 and DTS. I use Win7 and optic cable. When i test for DTS my Sony didn`t make any noice. Only work Dolby. I test with normal cables in Multi in all work. And optic...

What's connected to what? And which way are you going? Is a PC part of this scenario (you mention Win7)? Maybe you should start there.

The Sony knows DTS. The PC, who can say?

DTS is a bitstream-audio function and many sources need to be told to send it to their digital outputs because without decoding it will only sound like high volume static noise. The DTS-compatible receiver decodes it to its analog multiple channels. It doesn't suk. Look it up on Wiki.

The reciever volume will not ajust .. It is fixed at one set volume

Volume controls today are not potentiometers anymore. Manufactures use devices called encoders. When you spin the encoder it sends a binary signal to a decoder chip that will in turn increment or decrement the volume. Either your decoder chip is bad or the encoder itself needs replaced.

Cannot get dts surround. I am using a PS3 and the

DTS (digital theater systems) is the name for a company that has it's own proprietary digital encoding for the audio, just as Dolby Digital does. In order for your media to have audio output in DTS, it actually has to be encoded with the DTS software format, AND manually selected by the user to play in that format. Incredible Hulk is NOT encoded in DTS. Select a movie that has the DTS encoding by checking the rear label of the case on the format table.

Hi i need to buy just the chip part of the external hard drive do you gguys have any to sell? i broke the usb cnnection area on the chip of the external

by the chip part, are you referring to the controller board. this is the printed circuit board the sends low level commands to the servo motor and the read write heads. as well, the issues will mean that the board has failed and you cannot get the drive to spin up at all, you will have to replace the controller with a donor drive., or you will have to actualy take the controller board off the drive and swap a good drive controller board for the bad one. to get the data off it again. possibly sacrificing the good drive to fix the bad one. make sure the same number of lba logical block addressing matches the chs # and the model number match as well. the drive should be identical and around same exact year. this will not always work, but you might get lucky. if not prepare for a 174 to 400 dollar recovery cost with a company like Rapid Data Recovery they are a great recovery unit and helped mea few times. good luck with it. Please remember always have a backup drive eaven a usb external one touch backup is better then nothing and saves you thousands of dollars and your busniess eaven good luck and thanks for using fixya
