Had a problem with jack so replaced and had a short that started fire. Replaced mother board from one on Ebay. Now when I plug it in the lights on front come on but that is the only thing that is coming one. My son who knows something about computers helped me break down the computer and put it back together. Since I replaced the mother board I just get the lights showing that there is power.

There is. It would appear that the DC jack was not the only thing that was fried. If all your solder connections are correct, the mother board may have been damaged be the shorting of some part on the board, and burned open. Look for fuses, and "resistors that are have a "0" on them. they should read a short. if you find nothing. the board is damaged beyond repair.
Your power supply board is dead, you know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
Hi I presume you checked the DC power supply. Don't use a generic power supply on this model, because that will cause alot of different symptoms. I use the exact same model on service calls. A further way to test the mother board is to remove the CPU and memory. Carefully provide power and look for lights. If none, my next step would be to refloat the video chip. This requires special equipment. A replacement mother board without processor on eBay is $49.00 so it might be time to consider that. Good luck
most likely I would say sounds like your ac jack is shorting out this is common with acer computers there is one place that can fix this promblem it is in the internet type in jack repairs
there is a place in virgina that can fix this prombelm for $115.00+ 20.00 dollars sending fee
or you will prombally have to replace the mother board ..........
I've repaired alot of laptops... One thing that I found works the best is get 3 bowls or dishes.... Label them; 'Top', 'Bottom', and 'Logic'. Almost all laptops require you start disassembly at the base of the unit. Unscrew every single screw you see, make sure there are none left before you start on the top. The way alot of laptops are set up is that you unscrew the bottom, pop off the top casings/covers then unscrew the top screws. Once you've removed all the screws from the top and the bottom, there will be very little attaching the casings, so be careful. Remember to Unplug everything you see attached to the logic(mother) board, or you risk ripping a fixture off the board. Once you have freed the logic(mother) board from the attachments and casings you should very careful.
Now as you start work on the power jack, I Highly recommend you use a solder wick and flux to remove any solder left on the board from the previous repair. It is never a good idea to leave old solder on the board. You should be careful with the solder you don't want to short anything out by using to much solder. Once you have finished your repairs to the DC jack you should test it out plug it in to the AC Adapter and look for any visual indicators of life(i.e. charge batt light).... So now you know it works.
If you get it back together and it suddenly doesn't work its possible you have a case short. If thats the case look on the metal casing for any discolorations or blackness and if you find any place some electrical tape over it... it should be fine.
Good Luck. Don't be nervous its not as hard as it seems.
Hope this helps lemme know if you have any questions.
the motherboard and the power box should be replaced. you hade a short and the power box went out and the mother board shorted out as well. If you replace the mother board you will see. This happens alot to people. Check out the numbers on the board at type it in the web and find out what kind you have. you can find motherboards cheap on ebay.
