Will this work on my TV?

It should, making sure you have the right polarity wired into the DC plug for the TV.
But have you thought about an inverter for general use in the motorhome?
That way it wouldn't matter what device you had (within capabilities of the inverter) you could just use the power bricks that came with the device.

I did this in my 4x4, got sick of buying 12v adapters for every gadget I bought, ended up mounting a small inverter under the passenger seat. A bit of heavy duty cabling back to the battery and away I go with whatever I want.

Galaxy, thanks for the response. I do in fact have it hooked up to the motorhome inverter right now. The problem is that the inverter is 2500 watts and has about 2 - 3 amps dc overhead just to turn it on. Sometimes if I'm trying to make the batteries last longer, I would rather just use the more efficient DC power. The TV only draws about 35 watts which is about as much as the overhead on the inverter.

Yes. The 24V DC-DC converter should provide the voltage and current required. I can't imagine the TV will require special signals (like some laptop computers) so the only remaining challenge(s) is to get the correct plug and wire it up he right way around.

Show us a picture of it. It may be something common.

It looks like a 2.5mm DC plug, as a matter of fact the link to the power supply has the following in the part number.
PSAA-L010A, 24V 2.5A 5.5x2.5mm - 02697C
So I'd say a 2.5 mm diameter by 5.5mm long.

Should be easy to find.


Edit..yes down the bottom of the page it says the specs for it.

As to the 2500W inverter....yes, might be overkill to kick it into life just to run the TV !!

So, I ended up using this instead

http://www.amazon.com/gp/product/B008FLE7PA/ref=oh_details_o04_s00_i00

I noticed that after powering it up and then disconnecting it, there is still some residual voltage when I hook up the volt meter to the input or output. Maybe a half a volt or so, but I didn't leave it plugged in that long. I'm guessing this is from the capacitor storing the electricity. Do I have to worry that this could hurt my TV or Roku box? Is there any scenario where I could do some damage?

Thanks, Jim

No problems. I guess I should reiterate that the polarity of the plug must be correct.
