hello there. name is ryan lets see if this helps.
typically in a combination unit there is no rca audio ouputs on the tv. reason being is it is a combo unit not meant to be a item within a home theater system. it has the whole home theater built in it. ;) however if there is any audio output jacks on the tv you should be able to wire the surround sound unit up via rca cable output from tv to input on reciever for surround sound

sounds like you gotta power supply problem in the main unit. to repair this your gonna need a service manual most likely or you have to take it in to a repair shop to estimate for you .. if you post a schematic we will assist you in trouble shooting if you have any previous experience. Good luck.

I've seen this problem before with devices that have audio amplification circuitry.

In the cases I've seen, the connections to the speakers were the culprits.

First of all, you should only use the GPX speakers that came with the device. I don't know what their impedance is, but if it was 8ohms, you should only use 8ohm speakers. The same for 4 ohm, 6 ohm, etc. The safe bet is to use the speakers that came with the system.

If you are using the intended GPX speakers, and they're hooked up correctly, (only one speaker per output) then I would suspect a short in at least one of the speaker wires.

Amplification circuits apply fluctuating power to the speakers which correlate the sound wave. The power reaches the speaker, has an electromagnetic effect on the speaker cone, which pushes it out or pulls it in. This produces sound. The speakers job is to be affected by the amplifier, and convert the electric power into a mechanical movement. Speakers of different impedances respond to different levels of power. Ideally, your amplifier will supply power to speakers that will use it all up and return none.

An amplifier designed to drive 8 ohm speakers will get too much kickback from little 4 ohm speakers. When I've seen this sympton before, the amplifier had another circuit designed to monitor dangerous conditions such as this and shut down to prevent permanenet damage. Another dangerous condition might be a short in one or more of the speaker wires. Inspect each and make sure none got stuck under the table, or slammed in a drawer or pinch by a staple or whatever.

sounds like a bad solder joint that is cracked...as GPX heats up, the crack starts to get bigger and cutting off electric circuit, then cool down closes the gap and current resumes. First try breaking and then making all possible connections outside then inside unit. Then, if no success, remove the circuit board and clean it with alcohol and brush then carefully look at each solder joint with a magnifying glass. If one found, simply re-solder it.

Sorry I don't have a solution. We have this model and ours is loud also, at the very lowest setting. I disconnected some of the speakers, and sometimes have to put the working speakers into a drawer to lower the sound.

This is a website for the soundbar.

There is a pdf of the manual on the page

Most of those types of screws only require a 1/2 turn to unlock.
