No power from inverter

If you are only tring to run a TV off this inverter, it appears you may have a defective unit. If you have had this inverter for only a short time, contact the dealer/store where you bought it and seek their advice. If you have had it for 90 days or more you can still contact the dealer, but maybe it would be best to contact the coleman company. You can go to their website nad find out how to contact the division that deals with this particular type of product.

try jumping out the presureswitch this may fool the heater in too working ,

What does it invert?Higher voltage to lower or what?Either way,with 1200 watts being inverted,it is not a good idea to charge a battery with that kind of power.Batteries need to be charged low and slow.We are talking milliamps for hours.Fast charging a battery results in a very good chance of explosion,which is never good.Acid from the battery will go everywhere.

Inverter run on batteries sir, and if these batteries are not charged, the run time {the number of hours it will work} reduces.
S0, you will need to connect the inverter to a power source.Theses will allow your batteries to be charged and enable it to run for a long period of time.
Make sure your batteries are still OK.i.e working properly

It blinks because your computer is drawing too much current. Most of these give an exaggerated wattage range, and never give details about the true amperage available. the average laptop uses 3.0 to 4.X amps and is too much for these mini inverters. But they work fine on cell phone chargers.

Power supply board is dead,if green light on keep blinkings,notthing come on.Power green light is solid,nothing come on.Than ur Tuner signal board is dead.

Jump R and W terminals on the circuit board. Tape down door switch. Heater should start. Jump out R and G and blower should start. If neither works, bad board.

Probably has an internal fuse that is blown. You will have to disconnect it from dc power and take the cover off and look for a fuse that is blown, should be near the AC outlet or on the circuit board. Could be a glass tube or newer style automotive plug in type. Good luck.

Common problem with this set are the two 1000uF@25v capacitors and the 150uF@400v cap on the power supply board.

My Mitsubishi WS-73713 had the same blinking green timer light problem and would not turn on. I tried the reset button and unplugging power to no avail. I found that by simultaneously holding down the remote control "power" button and "volume" button for about 30 seconds the blinking light would go out and a solid green light would come on. Even though the solid green light came on the unit would still not power up. After doing this several times however the unit did finally power up in a normal mode and appears to be working again. It's worth trying before calling in for an expensive repair. PS - From here on out I'm sticking with SONY or Toshiba sets which have given be great service.
