Panasonic plasma tv led blinks 12


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.
http://electronicshelponline.blogspot.com/
If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

What benefit do 12 volt led light bulbs have?


Due to the solid state design of LED lighting, there are some important features that will be very useful especially when it comes to outdoor, landscape LED lighting. Safety of 12V LED lights. First distinguishing feature is safety. As compared to incandescent landscape lighting, low voltage LED lights are much more energy efficient and because of that, they are more fireproof. In other words, with lesser energy flow, the chances of fire getting started due to malfunction, overheating, or similar circumstance is relatively lower. Also, the electric short can not cause as much damage as with the 110V voltage lights. As opposed to halogen lights, there is hardly a fear of explosion of the LED light bulb upon overheating or other malfunction. Finally, LED lights are cold to the touch, adding to passers by safety.

I really don't have any idea as to what you're talking about here other than a battery and maybe a charger. Seems as if you're saying that you have a 12 volt 1.5 amp automatic battery charger connected to a 12 volt, 8.5amph battery but the red light on your charger is blinking. The blinking red light indicates that the charger is not seeing a proper connection such as crossed polarity connection or simply a poor connection. You say that the battery voltage has dropped from 12.5 volts to 9.1 volts with the charger connected. If this is the case, the battery is badly discharged and the charger is not charging the battery for some reason. The charger may be bad but check the connections to make certain they are correct and good. If they are, I'd replace the charger.

Good luck

Colorlogic Pool Light flashes like strobe


These swimming pool lights have a power-cycled feature. THis means that you can power down the light and then power back up in 10 seconds and the light pattern will change. It sounds like your light is not cycling properly. Power it down for a full 60 seconds. This will reset the power cycle. Then try turning it on and off in 10 second intervals. If it doesn't reset, you bulb may only be partially functioning and it may need to be replaces.

Please count the number of flashes of the Blue LED. It will flash Ex. 12 times and pause for 2 seconds and then flash 12 times again. The number of times it flashes will tell me more as to what the solution is. I am assuming the set works otherwise ?? What is the model number of the set ?

to test all y sub boards remove the main power connection to the y main and turn the tv on if it powers on one of those boards are bad.. remove both sub boards. and plug in the y main. if it powers on then that board is good either, put your multimeter on 2k omh and test the upper ysub boards black connector, the top 2 pins with negative to the 5th pin positive. you should read 500-1k ohm if its way under 100 there is a short.

the bottom ysub board place the multimeters black probe on the bottom 2 pins of the black power conection and the red on the 4th pin.. results are the same.

low resistance means theres a short in the board.
