1. Make sure the AC power source is ok.
2. Make sure the AC power cord is good with no damage.
3. Look to see if there is a reset button on the rear of the set. If not, then look for a blown AC fuse inside the set.

Since the set works fine on +12VDC, the majority of the TV set is ok. You have a problem in the AC power supply. It could be a blown fuse, bad rectifier / regulator, bad step-down transformer.

The TV typically runs from +12VDC. The AC supply steps-down the 120VAC and rectifies it into +12VDC to power the TV. At some point in the TV, there is junction point where the +12VDC from the sets internal AC supply meets the external +12VDC power source. Usually they are electrically isolated from each other with a switch or with diodes.

Please let me know if I can be of further assistance to you.

Good luck!

Alba tv blowing the 12v dc adaptor


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.

How can I operate my LG 26LE5300 LED LCD TV in my motorhome the most direct way possible (i.e....without an inverter)? This low power (40-50 watts) TV has an external brick to convert 120 AC to it's...


1) You need to look at the output current rating (AMP) of this AC to 24dc adapter, this 24vdc adapter is a regulated switching power supply that will maintain 24vdc output up the maximum current rating and also has shutdown circuits if the over current draw is detect and also if the output voltage goes up beyond 24vdc to protect the load (TV).

2) To use 12vdc to 24vdc DC-DC booster, it should have the following spec:

A) The output current rating should be at least 20% higher than the load requires to give its head room.
B) It must have regulated output that will maintain the 24vdc when the input (12vdc) will vary from 10vdc ~16vdc or higher since your batteries will not maintain exact 12vdc all the time.
C) It must have good protection circuits that will protect it self from reverse polarity connections, shorted output protection, over voltage output protection.
D) It should provide AC ripple spec on the 24vdc output, it should be in the milli-volt range (you will always get AC ripple riding on top of DC when you rectify the AC into DC).

These are the minimum requirement for your DC to DC booster, which you need to protect your TV and your motor home from burning down.
I hope I explain it OK to you.

Ac adaptor on my 32 Protron inch LCD TV no longer work


What is the current output of the adaptor? If it is AC and you use only the 12v to 3v it is ok. But if the current output of the adaptor is DC and you use both 24v to 6v and 12v to 3v there is some danger if use the new one. Remember that DC current have polarity.

This system uses in conjunction with the transformers a rectifier which converts the High AC current voltage (220V-AC) to a Low AC current voltage (12V-AC) and then the rectifier converts that energy into the D/C current (12V DC). The two diffrent 12V power sources are controlled, operated by a "electric" relay, via a roadside or electric selector switch. DS_TK TECH

12v &240v connections on an ENGEL COOLER


AUTOMATIC AC/DC CHANGEOVER: All Engel Fridge Freezers can be plugged into both AC and DC at the same time. The Engel is smart enough to use the AC while available and then automatically switch to DC when the AC is no longer working. It will also sense the resumption of AC power and automatically switch back to AC making it ideal for high hurricane areas and places where power disruption is common.

Are you certain the polarity of the connections to the TV are correct? If you connected them in reverse you may have damaged the TV. If there's a fuse in line check that too. BMW
