Question about GPX DV7500 System

Gpx dv7500 dvd player will not power on

It has been working fine for a couple of years, not used too often. Today we tried to turn it on. It powers up for a few seconds and then turns off permanently. It does this once each time it is newly plugged in . Never had an appliance that behaved this way. We just watched a dvd a few days ago. thanks for any advice

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.

No output from DVD/CD player to TV

Best bet/least effort is to get a newer, slightly more robust DVD player. This unit sells for less than $30. It costs more to ship it over from China than it does to manufacture the player. No kidding! For an ultra-cheap DVD player I'd go with a ~$35 player from wally world. Best of luck.

sounds like a bad solder joint that is 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.

Have you opened it first and looked for a blown fuse. I suggest you unplug the unit and first look for a blown fuse. If this does not help, go to the retailer or the store where you purchaced the unit and see who they send them to for repair. Good Luck
