So far I've attempted to replace the motherboard for power. Bought exact same on eBay but got robbed. That one wouldn't even allow me to get power... So any ideas on which direction I might go?

    It is a 42in plasma Sonya TV . Nicholas you have to be careful ordering parts on Ebay. Be aware of differences in AC power between countries. If you purchased as an example a 120v 60 Hz USA motherboard and then plug it into a 240V 50 HZ AC power supplier you blow up the motherboard. Also if the Hz is different it could cause problems also with syncing the scan rate for the screen photon gun.

    I did this with a hp printer did not even occur to be the difference in power voltage until smoke came out of the low voltage power board and a bright blue flash.

    does this device have a transformer in it . I think this would be a good starting point. Look for a low voltage power board and carefully measure the low voltages . Careful as colour TV's also have high Voltages that could be required . Will KILL ! if you get it Wrong or Blow up multimeter's Volt Meter. Check the incoming power to the transformer again be careful 240v AC KILLS

What sort of power . do you mean electicity or processing power. I would look at the AC to DC adapter power pack if it is a laptop and electricity. The battery could need replacing on the laptop but if you aint getting electricity like DC voltage out of the AC to DC adapter the battery goes flat. . A voltmeter could measure the DC voltage coming out of the AC to DC power pack adapter unit to confirm if power adapter is at broken.

    Sorry about mix up Brett. Its my TV that's having the issue. I could only type 200 words so this question was part 2. I have a 42in plasma Sonya TV. I thought I could repair it cheaper than paying someone or buying a new one.
    Any ideas for that?

Resets by itself

This might be an error / fault, somewhere at the motherboard. I myself have bought 2 identical new systems years ago. They are exact copies of each other, but one started (especially when wintertime was comming) started to reboot without any indication or warning. Sometimes it happened at booting (still black DOS-screen), sometimes when Windows XP was running a few seconds, or even later. However, after 1 reboot it seldom happened the computer would reboot again.
I've swapped all components piece by piece, and noted the problem was located at the motherboard.

So far I couldn't pinpoint the exact source of the problem, but I'm 100% confident it's an electronic component-failure problem. I think it might be a thermal problem at the PCB, something like a loose contact. Maybe something like this, together with bad caps or malfuntion of MOSFETS. But it's definitly something at components-level.

Hey there. Your motherboard is most likely faulty and is causing shorts inside the keyboards and mouses. You should get a replacement from your retailer for the motherboard.

I bought a inspiron 9400 off ebay and the bios is locked. Dell will not help me because I am not the original purchaser. please any help.

Only A Couple Things You Can Try Here.....

You Can Attempt To Clear the BIOS By Removing The CMOS Battery...
You will have to disassemble to get to it...Not sure offhand on your exact model whether your battery is plugged into the motherboard or directly soldered.. I am almost certain yours is a Snap in/out that gets inserted into a carriage on your motherboard... Either Way... You Will Need to remove it... Make sure your Power Battery is also removed... and your AC Adapter is not plugged in..
Then Press and Hold Your Power On Button To SHort Out The Connection... THen After 30 seconds or so.... Reinsert CMOS Battery...
Reinsert Power Battery...Plug In AC Adapter...
Attempt To Power On

Didn't Work... Option 2:

Try Using A Backdoor Password Or Default Pass...Go To THe Following Link For More Info On It:

Still Didn't Work... Option 3:

The BIOS Will Either Need To Be Flashed... Or You Will Need To Replace The Motherboard...

The BIOS ROM CHIP can be flashed (erased and written over) but it is costly... you Can Google Search That Information If You Choose To...
Use Search Term: Dell Inspiron Bios Flash

I recently bought a canon t70 on ebay. The seller mentioned that it was used, but failed to mention that the viewfinder was cracked. Can I possibly fix this or do I need to get my money back?

Hi there, and welcome to FixYa.

You should get your money back. Never buy something that you have to put money into to have it working properly. You should not attempt to repair this yourself. If you want to keep it, and pay even more money, take it to a shop.

Won't turn on at all

If he chewed far enough into the cord that it shorted out, then the power supply would have been killed instantly, but not before taking out the motherboard on the laptop with it.

The motherboards for laptops are rediculously expensive and a new laptop would be the way to go.

The next best option is to hunt around on eBay and look for one that has been dropped and had the screen smashed. You could salvage the motherboard from it, or transfer your screen the other way.
The good news is, people will pay good money for dead laptops on eBay for that very reason, so you could always sell yours there to help cover the costs of a new laptop.
Sorry for the bad news

Toshiba 490xcdt

Are you sure you used the charger with the exact specifications?

I once encountered a problem like this... try removing the battery and replacing it after some 5-10 minutes. It worked for me.
If it doesn't, try whether it would work only on main AC with no battery inside what-so-ever. Then - try with it.

Oh, and no, laptops - to my knowledge - do not have fuses... at least those 4-5 I opened didn't.

Hope this helps. I'll post up if anything else comes to mind...

Power on/boot-up problem

Have I got a story for you? Dell inadvertently used some defective capacitors in their Optiplex motherboards and some power supplies. From what I?ve experienced and read this affects the Optiplex 270 and early 280 lines. In my case my systems had video display problems and eventually ended up not booting. The giveaway is looking at the large 150 uf capacitors; they are the larger ones usually with an ?X? inscribed on the top. If the tops of the capacitors are flat you?re out of luck but if any of them are bulging (even slightly) at the top, leaking electrolyte or split Dell will replace the motherboard for free. This program is in effect till 2008. I wouldn?t recommend pulling the power supply apart but the flashing yellow power light for me has been a failed power supply. I would check out the motherboard for bad capacitors then call Dell. It?s likely they will replace the power supply if it?s in warranty, perhaps even if its out in light of the capacitor issue. If you?ve got some rounded caps on the motherboard I would also ask them to replace that as well. Let us know if you have any other questions and please don?t forget to rate this posting.
