It should have a red light on if it is in protection mode. If it does not have the red light then buy a new amp and check all you wiring

SOURCE: power to amp none to sub

If you disconnect the speaker wires from the speaker output terminals of the amp, does the light still blink with the music?

SOURCE: my amp indicator is blinking blue

yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

Should the interex surge protector have both red and green light?


the red may indicate a surge controlled but will no longer protect the equipment
most surge protection is only good for one hit and that fails the protection for more surges
read the user manual on it or go to a retailer and read the instructions on a new unit

      Disconnect the coaxial cable at the back of the satellite receiver or cable box by unscrewing the coupler on the cable end.

    • 2
      Attach the cable to the RF IN jack on a surge protector and tighten the coupler clockwise.

      Connect a second coaxial cable from the RF OUT jack on the surge protector to the input on the cable box or satellite receiver. If this stops the hum, congratulations: You're done.

      Unplug the subwoofer's electrical cord from the power strip or wall outlet if it is connected to the same circuit as the AV receiver. The amp in the AV receiver and the amp in the subwoofer are in conflict over the grounding of the electrical circuit.

    • 5
      Plug the subwoofer into its own surge protector and connect the surge protector to a different wall outlet than the AV receiver uses.

    • 6
      Disconnect the subwoofer cable from the back of the sub and the AV receiver if all other measures fail to stop the humming. Reverse the plug connections so the plug that had been connected to the receiver is now connected to the subwoofer. Turning the cable around may solve a problem known as ground-loop hum by reversing the shielding wire inside the cable.

Had power surge. Tv was on surge protector. Now no power will come on and just makes a buzzing sound.


Have you tried plugging it in without the surge protector? I would wager that either a) the surge protector needs to be reset/turned on and off depending on the model or b) either your TV and/or surge protector have been damaged by the power surge.

Try plugging the TV straight into the outlet and see if that helps.

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.

Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.

If the issue continues to occur, service may be required.


Thanks for using Fixya.

Most likely the sub and/or the control unit got spiked from the surge. Now I would double check the fuses on the unit because some times they will blow and you just need to replace them.

Also if you have worked on electronics before you may just need to replace capacitor on the unit as well. Anything past that and you will need to replace the unit.

Note if the satellite speakers use standard connection you will be able to use them with another receiver as well.

Let me know if you have any more problems or questions

My subwoofer keeps poping and then stops working


larryagross,
Sounds like you blew the speaker! The amp is sensing the voice coil is connecting to the speakers magnet or iron core and is going into a safe mode. It is possible to blow the coil even when the sub has a built in amp.

First make sure that you have the gains properly set ans not all set to their maximums. Second, disconnect signal to the sub then unplug the power for a few minutes. Third, plug the sub into a source of power on a different circuit using a surge protector.

Does the speaker make any popping at the time it powers up? If so you have a amp problem. If there is no sound produced, connect it back the the system using a different signal cable. Does the speaker now pop again when sound is produced. If so the speaker has failed. Contact a Velodyne repair facility.

Reset Surge Protector


Hi,

You can fix it by doing this. but first you need to make sure you leave your house for at least 4 hours so you don't have to be hearing that frigging noise, IT CAN BE DONE! i fixed it.
my unit would start beeping as soon as I plug it in wall, and red light come on, the software is telling me the battery is unplugged
this is what i did in order.
1. unplug all cords, connected to the unit, and power cord to the wall.
2. hold the power button
3. still holding the power button, Connect it to wall. (red light would be on but no beep)
4. I watched TV for 6 hours, red light still flashing
5. disconnect from wall
6 connect back to wall

I heard the unit click one time and green light came on, is charging now....

Tv won't turn on


I suggest you unplug the set for about 15 minutes and then plug it in and try again. Sounds like you may have had a power surge/bump in the middle of the night. Althoguh you are using a surge protector, doesn'r mean the devise hooked to it can't lock up during a power surge.( Surge Protectors are an insurance policy only, not a garrentee ). If unplugging the set and waiting doesn't fix it, it will need to have the power supply section of the board repaired. Good Luck
