I changed fuses as suggested in this forum and when I reconnect power the player pops the new fuse. Bothy constant and ignition switch power are hooked up right. Sounds internal and is it worth fixing?

Re: Power connected right, pops fuses in player
No one evidently wants to tell you that your Radio is shot. The circuits in the head units is not worth repairing. It is too minute and hard to do to the point it isnt worthy of attempt. I do not mean to be the harbinger of doom here. Just get a new head unit and this time dont get an Audiovox.

Most all aftermarket radios have their own fuse next to the wiring harness plug. Depending on the brand, it may only take a few minutes to pull the radio out of it's sleeve to check for the fuse. Usually, you can pop off the trim ring to see what you are working with.
You may check your fuses and relays you have a AC clutch relay in the battery box that has two fuses feeding it they are also in the fuse box under hood fuses 48 and 24 bothy 10amp fuses. fuse 24 is hot all the time and fuse 48 is only hot when car is running
it is possible that the power supply unit in the DVD has failed. You will need to open and ccheck, the fuse might be open and if a new fuse blows out then the SMPS unit is faulty.
Possible that the Sm driver IC /driver has failed. Possible also for allied components to have failed.
Or else you can change with a new unit.
try unplugging the battery and wait about ten minutes...to let the computer reset..then reconnect the battery..if that doesnt work..try popping the battery with jumper cables from another car...(while connect)
The end of the plug which gets inserted into the cigarette lighter/power port should unscrew. Inside is a fuse. You need to replace it with the identical size and rating of fuse. Check the unit with an ohm meter for any shorts between both conductors. If the unit is shorted toss it and get a new one. If it isn't shorted it should work with a new fuse. Let me know if you need any more help.
Pop the top of the DVD player and check the fuse. It's located right next to the AC power plug on the inside. If the fuse is OK, replace the DVD player. Repairs cost more than a new unit. Sony has DVD players from $ 40. Any repair on any device would cost more than that. If your lucky, the unit just took a surge and blew the fuse. Hope this helps
You know whats connected to the fuse, now start systematically disconnect each component and each time you try the fuse same fault, reconnect, till you ge t to the component which you disconnect and do not blow the fuse, now you know it is in that component start tracing the wires/bulb connections. , have 10 spare fuses ready'
since it worked before and you didnt change anything and now there is no power it looks like you blew a fuse when connecting wires. check the radio fuse on the door panel, and check the int. lighting fuse under the hood of the car. take both out and see if they are blown, if blown buy new fuses and replace.
