There are 8 40A fuses inside this unit. In the following pics you will see a bank of 4 and another bank with 3 of the 4 removed. I'm currently working on mine as it will cost me more to ship and have Cobra repair than I paid for the unit ($133 to repair). Good luck with your problem

Hitachi model# 50ux23ka no power???


The green ones are each tied to a voltage source in the power supply of this set, try to see if one goes off or dim before the others, the red one should always be on.

If one can be seen to go out first or dim first that voltage line is being held down or has a problem.

Its meant to be a way to know which voltages are up and also to narrow down where a problem might be.

I am using 2500 cobra inverter .when i go to plug in extention cord led comes up ( OPP ) and and i do know what that stsnds for ? no power


Short Circuit Protection - OPP



If the

AC output of the inverter is shortcircuited

for one second or more,

it will shut down to protect itself.

The meter will flash as shown to

indicate Short Circuit Protect and

an alarm will sound.

To restore normal operation,

disconnect the short circuit and

turn the unit


Off and On again
using the

Power Button.


Current flowing down an unintended path, try a new extension cord

The output(w) is indicating o.oo and it's indicator light is red .I only have a couple of floor model fans plugged. Should it be showing something and should the light be green?


inverters run on a square voltage unlike normal 110 runs on a round voltage, the only 2 things that won't run on the inverter is fans and electric blankets

I had a monitor and xbox 360 power supply plugged into the inverter. It has been working for at least 2-3 months now just fine. Then all of a sudden, it turned off. I unplugged it and thought maybe it...


  • First thing I should ask is have you tried to plug something else into the inverter to see if it is the inverter or a surge messed up your monitor and X-Box?
  • When you say turned off do you get a solid red light when the inverter is on and you are trying to get your X-Box and monitor to work? A solid red light means voltage overload.
  • A blinking red light means you are having a current overload.
  • If the internal alarm on the inverter goes off and shuts down with a red light this means you are having a voltage shortage.
  • If the red light starts to blink this is a temperature overload.
  • Keep in mind that this inverter will start automatically back up as soon as what ever issue it is detecting is resolved. There is no fuse to check inside.

  • If your inverter shuts down from thermal overload then wait 15 full minutes before trying to turn it on again.
  • If you don't have any blown fuses and no burned wires make sure that if you are using over 150 watts and hour you go right to the battery rather than a cigarette light adapter as the stress can burn them wires connecting to the cigarette lighter up.


  • Hope this helps and thank you for using FixYa.

its an error. hold down the power button till it beeps once. the hold it again till it beeps twice. The moment it beeps twice take your finger off and instantly hold it down again. your ps3 with give you 5 onscreen options, hit #3 and only number 3. that should fix the problem. You can also youtube "how to fix disk error on ps3" and people will should you how to do these stated steps.

My ps3 it goes green beeps twice then goes red and flashes on/off


you might be holding the power on button to long. you hold the power on button until it beeps to reset the video output. try turning it on by using your controller. just press the ps3 button and if the red light is on then it should come on.

Stays in standbye and will only flash green (power on) twice before staying in standbye


The 6 inverter transformers on the bottom of the picture is the problem and what need to be tested.
Unplug the 6 wires that goes to the LCD screen. Use a multimeter to test for resistance from each output plug on the board. The one without the resistance is the bad one.
If this doesn't locate the bad one this way, Each plug should give out DC voltage if working properly. Test each plug for voltage.
The TV will automatically turn off in a couple of seconds like before. You'll have to keep pushing the power button to test each output plug for voltage.

Soon as you find the bad Inverter Transformer, just solder in a new one and the TV should work fine after that.
The part # for the Inverter Transformer is LTZ2PC0MS008.
Here's two places to get them:
