Well it would void the warrantee, but you can take the back panel off and the power supply will only have two leads (3 if grounded) in from the plug, and out to the crossover. It sounds as if you are correct that the power supply is bad.
so if you have the back panel off, and the unit plugged in, you will be able to read 115 or so volts right at the solder points. then those wires will go into the power supply. test them where they go in, and where they go out and give me a voltage. do not worry about positive and negative, the meter will just give a -115 if its backwards. Smell the unit, usually you can smell a burnt smell if its blown.

Check fuses on panel, then check all connectors, check for kinked or frayed wire, then lastly, the circuit board for your panel! Not an easy task as you are checking for continuity between connections. If its the circuit board on your arm rest I would suggest a junk yard for a known good operating board. Make sure they have some type of guarantee as these are expensive new! Hope this helps Interior Fuse Box Location 2003 2009 Lexus GX470 2007 Lexus GX470 4 7L V8
The video above shows how to replace blown fuses in the interior fuse box of your 2007 Lexus GX470 in addition to the fuse panel diagram location. Electrical components such as your map light, radio, heated seats, high beams, power windows all have fuses and if they suddenly stop working, chances are you have a fuse that has blown out. If your GX470 is experiencing electrical problems, you should always check the fuses first, because they are relatively easy to check and cheap to change. Some Lexuss have multiple interior fuse boxes including in the trunk - the video above will show you where the interior fuse box of your 2007 GX470 is located. If your GX470 has many options like a sunroof, navigation, heated seats, etc, the more fuses it has. Some components may have multiple fuses, so make sure you check all of the fuses that are linked to the component in question.
If you need to replace a blown fuse in your GX470, make sure you replace it with one that has the same amperage as the blown fuse. If checking and replacing the fuse for the component in question doesn't work, we recommend seeking assistance from a trusted professional mechanic. They should be able to figure out if the component needs to be replaced or if there is a short or some other problem with your GX470.
Bad DOG! Break out the checkbook, you may have blown the computer. Need to start there. Not sure if there is reverse polarity diode protection or not. Have it checked. Even at a scrap yard they won't be cheap.
check for 230v not 110 (on line to ground). SO checking L1 and L2 should show 230 v if not you have a fault in the timer or the breaker is toast. depending on the timer you can clean the points
hi,
i have a jamo 250 sub.the blue light is working.when i connect the jack to the left line IN according to the manual it makes a sound as well.but seems not working.is it related to the fuse????i know the fuse box.but i dont know how to remove the fuse to check.pls help me out.my receiver is onkyo tx-sr 608
If its out of warranty you might as well open it up , and if your lucky it might only be a fuse to replace , if it is fused inside it will probably have blown before it could do any damage to circiuts . hope this helps
Hi Thanks for the post. The box has no warranty as it's bought overseas. Checked with the dealer here and they confirmed it has no warranty.
Yes. It's definitely looks like a power supply issue. problem is I dont have a wiring diagram to check.
It has only 2 leads, no ground.
