Looking for ac power adapter

I bought an Advueu LCD tv a couple of years ago. Something tore up on it and I am thinking it might be the power adapter. I have searched several places but can't find one. It has "Chi" written on it and CH-1932. The input is:100-240VAC ~47-63Hz 1.5 MAX Output:+19VDC------/3.2A 61W MAX. Polaris Electronics(Dong guan)Co., Ltd. Do you have any idea where I could find this? Any help would be appreciated. Thank you

Re: Looking for ac power adapter

Have you tried ebay? craigslist? etc.. I have noticed that ebay seems to be incredible for that, but be careful and read each auction carefully.

AC adapter 4750z

The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

My sons Dell Vostro 1500 has a problem with the AC adaptor. It will run the laptop but wont charge the battery. Any help will be appreciated. Thanks,David

If it will run off the AC Adapter but won't charge the battery then odds are it is the battery that won't take the charge and not the AC Adapter's inability to charge anything.

Google "dell vostro1500 battery" and change to shopping. You will see many available knock off battery's starting at 20 dollars.

Although AC Adapters go out too. They last a lot longer than batteries do. Today's batteries just don't last. I would say average life span is a year to a year and a half.

I have a alesis dm5 drum module. I have lost the power supply so I bought a universal power supply buti dont want to harm the system. How do i set the power supply up?

NEVER use a universal wall wart supply... it is too easy for the settings to be changed and blow the unit.

It appears that the correct power adapter supplies 9 volts AC at 1 amp (1000 ma)

Most universal adapters supply DC rather than AC.

There are sellers on eBay selling the correct adapters.

Toshiba Laptop not Taking Charge

ya the solder connection connecting the ac power input onto the transformer is probably weak. aside from taking the case apart and resoldering the connection, not much else you can do.

Hum from dell laptop power adaptor when using a sound system

as i understand you are facing this hum on all the three AC adapters,
there could be any of the following reasons for that
1) If the laptops were bought within the same period and all the AC adapters came from the same faulty lot

2) Or the AC adapters are made in this way so they produce this hum always

Try calling their Tech support helpline for Dell and see if a replacement can help you or if the AC adapters have a design fault of producing hum is their a solution that they have for it

If you Think my solution was of any help please do rate me

Latitude D505

Just repaired a laptop with the same symptoms:
Won't charge the battery, won't power from AC.
Also if you power the AC adapter when not connected to laptop you get green power LED on the adapter. When you plug it in the laptop the green power LED immediately goes out.

Opened it up and found SO-8 P-ch mosfet by the DC input socket. Source (pins1,2,3) is connected to the inner barrel (+19.5V), Gate 4 gets driven low, applying the input to the Drain. (pins 5,6,7,8) On my board the drain was short to GND. Applying power directly to the Drain via a current limited bench PSU (set 1A limit) showed a couple of volts.

Placing a finger on the opposite side of the board revealed a SMT ceramic cap getting hot.
CP13 I think. Opposite side to the power connector, almost under it. I would guess at 1206 or slightly larger and there is an 0402 cap just next to its bottom pad at 90 degrees to it. Cap was glued before soldering so had to flow both sides at the same time with a soldering iron and force off. Would likely have been 1uF or bigger 25V. Removal restored operation. Runs OK without but would suggest putting something in there 0.1uF 1206 50V, perhaps a couple stacked ?

BTW you have to strip down everything and remove the main board to get to the cap :-(

Hope this info is of use....

Ac power adapter

Both at Walmart and Radio Shack you can find universal adapters that allow you to change the connector and voltage to fit the device. Try one of these, you can usually pick one up for under $10.
