LED's are current operated devices. In your case you are depending on the internal resistance of the battery to limit the current. This resistance is not a reliable limit since it depends on temperature, condition of the battery and load. This would be considered a very poor design. Here is an idea. Measure the current and include a resistor to achieve the rated current

More than likely it is the power board circuit that is broken on the tv. You can email or call the manufacturer for a cost estimate, if you have no factory warranty left. More than likely it will not be cost effective in repair the tv than just buying a new one. This is a common issue on bargain price tvs. Panasonic makes the most reliable tv in the market today. Hope this will help you out

10. why are my speakers not working?

Check the monitor's OSD (on screen display, the menu for monitor settings). The computer does not need to be on for this. The monitor does need to be on. There are buttons precariously placed on the monitor. Push them to find the OSD. Push them to navigate through the OSD. Once in the OSD look for a place to enable the speakers. Look for a place to turn up the volume to the speakers. Look for a place to reset the OSD values back to there factory defaults. Some monitor buttons use LED lights on the monitor itself as a way to configure the monitor's settings. Its possible the audio cable from the computer to the monitor is broken. Its possible the computer is not configured to use it's sound card. OR The sound card could be broken. Test with a pair of headphones to see if the sound card outputs sound.

I see that on Harley's more and more though,it seems that is allowed or they are granted a bit more lee-way(sp) than the sport bike community.it could be just the area i live in. blues and reds and frowned upon.
