I have had my Kaboom for a long time. One day it just would not turn on. I tried a differant power cord, and batteries, nothing worked. I have taken it apart, and nothing is burned, or loose. Could the power supply gone bad? What should I do, so that I know what to do to fix it?
Could be a blown fuse... it's located behind the right end woofer when looking at the unit face. Remove the round plastic molding and then remove the actual woofer. You will then have sight of the fuse... it's really hard to reach, will need something like long tweezers to reach in, grab and remove. Replacing is also challenging but you will figure it out (1x 250v 1.25A glass tube fuse)

Re: no power on my JVC Kaboom
I would rule out the power supply simply because the batteries won't run it either. The internal plug that takes the cord should be checked for cracked solder joints, because the plug goes to battery mode when cord is removed and AC fuction when cord is plugged in. It is possible it may be an audio output problem given the age of the item.

No solution, mine does the same exact thing but blinks orange five times. I got an error message that said click to fix it. I did it and the computer tried to reset itself but simply died. With brick cord out...nothing happens. Same with battery same with power cord in. The battery was fine.
It may have died during a forced windows update.
I hope someone comes along otherwise it's "buy a mobo" and buy a battery and so on....
I know this sounds silly, but check the switch on the back of the projector. There is normally a hardware switch, somewhere around where the power goes into the projector. Make sure this is on. Second, try taking out the bulb, WITHOUT TOUCHING ANY GLASS, and replace it. There is often a safety switch that prevents it from powering up without a bulb. Also, try using a different power cord, or try using a different outlet. If it works with a different power cord, your cord was bad. If it works with a different outlet, your outlet will need to be inspected by a qualified electrician, to make sure there are no shorts or other hazards. If none of this works, contact Sony about getting the projector in for repairs. Please do not try to open the projector your self, there are a lot of capacitors that store energy for long periods of time.
If you press the power button and nothing comes on at all then something isn't providing power to the laptop as it should and you may likely need to replace the battery or the power cord.
Find a replacement battery. Change your battery with a new one then plug it up and turn on to see if this works.
If replacing the battery doesn't work then replace the power cord and trying turning it on again. If this doesn't work either, you have a more serious issue going on.
Not too long ago, I was on vacation, my laptop had been working fine until suddenly it wouldn't come on at all. I went into the office to grab a new battery and power cord. (I work on computers so I had spare parts in my office/Tech Room.)
I got home and replaced the battery then tried to turn it on using the old power cord...didn't work. This was a brand new battery so now I knew that I could rule out the battery as the issue...the only two things left to troubleshoot were the power cord and the laptop itself.
I put my old battery back in the laptop then tried to turn it on using a different power cord and it worked. I didn't need to replace my battery or laptop. The power cord had failed.
I hope that your issue is as simple as this solution. Try confirming whether your battery and power cord are still working...you may just need to replace one or the other.
Are you leaving the DS charge until the light comes off? Remember that there are two likes too, one for charging and one for power. If you're just charging for some random period of time (lets say... One hour) then your Battery isn't going to be fully charged. The best way to ensure that your DS Lite is charged is to leave it charge until the charge light turns off. You can play your DS Lite while you are charging (I do it all the time), but it just means that you're just running off of the outlet.
A good test is to charge it fully (until the charge light comes off), unplug the charger cord (Make sure it's secured tightly to your DS while charging), then play for a little bit, your light should be a normal color (green).
If you cannot even play by using the outlet, then you need to find a charger cord that actually works (You may need to send in the charger for replacement). If the same thing happens with 2 different batteries (assuming that you have two official Nintendo batteries).
TIP: Also run your fingers across the Charger cord. You're going to get a slight friction burn from the rubber, but you're going to get all of the kinks out of the wire in the cord. My charger cord had a similar problem (did not charge all the way, only charged until I moved the DS) but when I ran my fingers across it (pinching) it worked again.
Also check the pins in both charger cords, charging will not work if one pin is missing, nor if any are bent.
