Sound on samsung plasma tv. model #hln617wx/xaa


Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

I have a 2010 cobalt lt. Today both my feont speakers quit working. And now my turn signals make no noise. Or the door chime or the seatbelt indicator does not work. What causes this and how do I fix it?...


The chimes an turn signal noise come out driver door speaker . Both front speakers not working could be a blown circuit fuse inside the radio or just blown front speaker channel . Your best bet , take it to a GM dealer or someother qualified repair shop . You have no idea of the complexity of this . The radio can set DTC'S - diagnostic trouble codes , believe it or not !
DTC B1025, B1035, B1045, or B1055
DTC B1025 01: Audio Output 1 Left Front Circuit Short to Battery
DTC B1025 02: Audio Output 1 Left Front Circuit Short to Ground
DTC B1035 01: Audio Output 2 Right Front Circuit Short to Battery
DTC B1035 02: Audio Output 2 Right Front Circuit Short to Ground
DTC B1045 01: Audio Output 3 Left Rear Circuit Short to Battery
DTC B1045 02: Audio Output 3 Left Rear Circuit Short to Ground
DTC B1055 01: Audio Output 4 Right Rear Circuit Short to Battery
DTC B1055 02: Audio Output 4 Right Rear Circuit Short to Ground

Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier have a DC bias voltage that is one half of the battery voltage. When using a DMM, each of the audio output channel circuits will measure approximately 6.5V DC. The audio being played on the system is produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3V AC and slightly higher.
DTC B1287 01: Amplifier Control Signal Circuit Short to Battery
DTC B1287 02: Amplifier Control Signal Circuit Short to Ground
DTC B1287 04: Amplifier Control Signal Circuit Open

The radio provides a remote amplifier mute output circuit to control overall muting of the remote amplifier. The amplifier receives pulse width modulated (PWM) signals on the control circuit at varying duty cycle percentages for controlling muted and unmuted functions of the amplifier. Circuitry internal to the radio monitors the remote amplifier mute circuit for faults and sets the appropriate DTC when faults are detected.

My Toshiba 36" CRT TV has no sound any ideas?


Check its speaker and audio output section circuits for the fault

Kdl-32v4000 sound


Check the speaker first. Check if there is any sound output comes from the audio out terminals at the back of the TV, by connecting them to any external audio out devices; such as an amplifier or so. If there is audio output comes from the external source such connected, and no audio output from the TV; since the speakers are good, the fault is with the audio output section circuit inside the TV. If there is no audio output from the external sources too, the fault is with the audio processing section circuit at the main board. If this is the case, main board is faulty, and should be replaced.

No sound


Test on the audio output amp for a tone, check on speakers, if there is a tone you have a front end fault which could be the audio processor. If ther is no sound connect from the audio output to an amplifier for an output.Then you are lucky.... Hope it works.

Toshiba 42H 94 speker sounds like its underwater


There may be a fault with the speaker driver, or the output stage circuits, or the audio decoding circuits.

Without proper troubleshooting, it is impossible to pin-point the exact fault.
