Check the adapter itself bow out, when it is plugged to Wall AC socket. Do not load it to TV, and check this. If it blows up, the fault is with the adapter itself. If it don't, the fault must be within the TV circuit.
radio shack multi adapter.way cheaper.Make sure you match the output ratings of your factory adapter.Batteries plus (or the inter-web) is another place to find them.Also check your electrical output at the wall socket,it could be the real problem.

http://www.lcdpayless.com I placed my
order on Thursday and went out of town for the 4th and I checked my
mail today (Monday) and it was there. I plugged it in, the power came
on and the tv works perfectly....plus the new cord doesn't have an
The cord is pricey at $117, but it beats buying a new tv. The company
accepts returns minus a 20% restocking fee and shipping, so I figured
worse case scenario I would only be out of $40+bucks if it didn't work
and I had to send it back. Hope this
If I understand your description correctly, you have two TVs that use the same model adapter, and both adapters have failed. In that case, I would suspect a weak design, or you may have put them in some place where they were overheated or zapped by power line surges. If it appears to be a design problem, you may want to consider using a substitute.
The adapter should have the output voltage and current marked on it, for example, 12VDC 2300mA would be a 12 Volt, 2.3 Amp output. The polarity is usually marked with a diagram showing whether the center in or hole in the plug is positive or negative.
You can use an adapter with the same voltage and plug style (including polarity) and the same or greater current output. If you find one with the right voltage and current, but the wrong plug, you may be able to change the plug. Just be absolutely certain you have the wires going to the correct terminals; reversing the polarity could damage or destroy your TV. Do a proper solder job on it; simply stripping the wires and twisting them on will not be reliable.

I found a power supply for this TV on Ebay but it is about $150.00 and is not guaranteed for more than a month.I found it after I sent for one that did not work with the TV.If I do try the right spec unit...12V 3Amp with light and fan and it works, I will try to get back to inform you all....CDM
It could be the AC adapter. That is easy enough to check with a DMM. Turn on the meter, set to volts dc, push red probe into the hole in the output power jack and touch the black probe to the outside of the same jack. Have someone plug the AC cord into a good outlet(one you know has power). If the adapter is working you should see 12 vdc displayed on the meter. There still could be a problem as I recently found an adapter which displayed the correct voltage with no load but little or no voltage with a load. Testing with a load is a problem if you are not familiar with the procedure. Odds are if you have 12 vdc the adapter is fine and you have a short somewhere in the monitor. If you are handy with tools and feel confident, remove the back of the unit and check the fuses in the power supply. If they check OK you probably can't do much more. Unless you are an electronic tech you will need to take the unit to a shop for repair by a qualified tech. Good luck.
