My dx4 was working 2 weeks ago. took it to work, and it worked. now i just plugged them into my computer back at home, no sound. blue led light is on, no hissing or buzzing. played with volume, changed wires, still no sound. i tapped the speaker without the power controls, and the opposite speaker made a tapping noise...same if i do vice versa. any ideas or suggestions...thanks in advance.

change mechanics --or bring back and have them fix correctly when they did the engine work doesnt sound like was done correctly and now you may have a bigger problem

the best thing to do is to have the car scaned with the diagnostic computer to see what fault codes are stored.
acording to the fault code you'll be able to work out what's wrong with it.
I'm sorry i ca't be anymore helpfull.

Sounds like it might be the slip rings that carry power onto the moving part are worn or making intermittent contact.

This could be a few things. It could be a bad power cord not charging the battery or the machine. But it could also be various other things. The cheapest and easiest thing to try is a new power adapter.

The same thing happend to me. I, unplugged the cam. reinstalled the drivers from the toshiba cd. rebooted. plugged my cam back in. and It was working normally again. Then I reinstalled livemessenger rebooted again and everything is worked fine. Good luck with it mate.

Here's what happened (The fix is at the end):

8 months after buying my Toshiba A135 the battery began charging only intermittently. It also would not run without the battery. I put up with it for a month then took it back to Best Buy to get it repaired under warranty. They kept it over 2 weeks then gave it back saying it was the battery, which they replaced. One week later I had the same problem again. Back to Best Buy. The guy at the counter said it was probably the battery, they had encountered a lot of that. I said no, explained it, and gave it over to be fixed. 2 weeks later I got it back. They had reset the BIOS, no hardware replacement. I got it home and it was not fixed. I took it back the next day. They kept it 2 more weeks. They replaced the motherboard. I took it home and...you guessed it the same problem on the day I got it home!!! I took it back with one week left on my warranty. I don't remember what they replaced the last time but I think it was the motherboard again. I got it home (2 weeks later) and THE SAME PROBLEM on the day I got it home. So, the lesson there is that Best Buy computer maintenance SUCKS!!

I called Toshiba to try to get them to fix it for free, and out of warranty. After several frustrating minutes of conversation with an accented person who just kept telling me that my warranty was up, I hung up and called back and got an English speaking person. SHE was very helpful, listened to my problem, agreed to give me a one-time fix ticket. They paid for the postage. When I got my computer back it was mostly fixed.

The problem was the module at the back of the computer where the power cord plugs in. It was defective. Some wire or solder had gotten loose. They replaced it and it worked fine after that, except that when it goes into sleep mode it will not wake up. I fixed that by turning off all the sleep mode options. BTW, a friend of mine with the same computer is now having the same problem.

ether the power supply is bad or your outlet is not grounded

check power ac adapter and batery if the batery is ok or charge do a test to the hard drive and memory ram loock on BIOS
