Question about Televison & Video
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 someone who is able to repair the adapter. I came real close to just chunking the thing, but someone from this board, I think, told me about him. I emailed it to him and within the week he'd fixed it. Below is his name and email address:
