Changed battery on 2005 Toyota Sienna, dvd player doesn't work

Most probably there's a problem with the laser head.

Hello, I hope this helps. If no change then you probably have a hardware/ wiring issue and the dvd player may need to come out. Please advise
1. Confirm the DVD RSE system is inoperative. (blank screen) 2. For vehicles with Toyota navigation system: Perform the following procedure to turn OFF the RSE Lock function. A.

Under the "Rear Lock" option, press the "OFF" touch button and then press "OK" in the upper right part of the display. D. Press the DVD switch on the RSE system (if a DVD is NOT already in the player, insert one) and confirm screen is ON and the system will play DVDs. 3. For vehicles without Toyota navigation system: Perform the following procedure to turn OFF the RSE Lock function. A. Push the Audio Control knob multiple times to cycle through the various options (Bass, Mid, Treble, etc.) until "REAR LOCK" is shown on the screen. B. Turn the Audio Control knob so the display says "OFF" next to "REAR LOCK". C. Press the DVD switch on the RSE (if a DVD is NOT already in the player, insert one) and confirm screen is ON and the system will play DVDs. 4. If the above procedure resolves the concern, explain the system operation to the customer.This procedure is described in the Audio/Video" section of the vehicle Owner's Manual. 5. If the above procedure does NOT resolve the concern, perform RSE diagnosis using the Technical Information System (TIS), 2006 model year applicable vehicle Repair Manual.

Good day!

Old battery, (have it checked at local auto parts, the cold cranking amps will be low) or a bad starter, ( this can also be checked, but you will have to remove it)

you might of blown all your relays thay are under your hood driver side i belive

Is DVD player on? if it's not, check fuses under dashboard.

All of those are tied into the same fuses or they are tied in somewhere under the dash, You can get a fuse tester for a couple of dollars if you dont have a meter to see if th fuses are good you should be able to pull the fuses and see if they are bad. Dont forget when you check the fuses in the car, make sure and check the fuses and the relays in the fuse box under the hood.

Where exactly is located the fuse;
inside the radio?
behind the radio in specific place?

please, clarify

we have the same problem

threr is an updated rear drum for sienna's rear brake noise.you need to check to see if yours has them already. they are a much thicker and stonger drum. cannot tell you about the player. did not have any dealings with that issues.
