Just replaced power supply, double checked the watt/v, plugged it into wall panel and a pulsing heart beat-like sound comes through the speakers--the red light power indicator light pulses on and off as well on both the wall panel(inside of it only visible since I removed it from wall) and the wall control IR panel.
Please advise.......The shop guys say it's the panel, but that costs $174.00!!!!

A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.
Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here.

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.
Things You'll Need:
Home theater receiver Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores. 2 RCA subwoofer cables 2 subwoofers
Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.
Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..
Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.
Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.
Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.
Tips & Warnings
Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.
Disconnect the subwoofers from the power supply while making the audio connections.
Hiya, Sorry to say it does sound a little like there is power supply damage. They are generally not to difficult to sort out but will require someone with electronics experience IE friend, shop in the area etc. Shouldn't be to much provided it is only power supply
you may want to re check all your connections.
are you plgged into a power bar or directly into a wall socket.
also you may have a defective power supply on the system . you can also check this website out it is free to join and you can download manuals and get help http://audio.manualsonline.com/manuals/mfg/jvc/jvc_th_thm505.html
