Question about LG 50PX1D 50 in. Plasma Television

1 Answer

No Power On startup got a small pop and lost power to TV. Had tripped house breaker so I reset. Didn't help. Unplugged and let sit for 5 min.,plugged back in (directly into outlet). Still no power. Appears to be good power to outlet. Almost like it blew an internal fuse. Does it have one? Thank You- Dave

There is a main AC fuse on the power supply bd. and a couple of ciramic fuses on both the ysus bd and the zsus bd. This symptom most of the time means either the ysus bd, the zsus bd. or both have failed. Difficult repair for a customer and most likely will need to have a qualified tech diagnose the problem. Most times it is the ysus that has failed and a realistic price to repair this is from 400 to 500 dollars.

When I turn on my 60 inch LG TV it pops the breaker. Can I reset the TV?


There may be a short in the power supply so resetting won't work.

My fuse box in my home keeps tripping, it's only


sounds like your breaker has reached the end of it's life.
I'd have it replaced and see if the problem continues.
That's when you will have to trace the fault if there is one.
More than likely it's the breaker unless you have added more
power consumption items to the circuit recently.

Please help my side by side ge fridge freezer is tripping our power I have had it for 2 year we moved houses I left it unplugged for three days in our garage then moved it into the house and plugged it in...


Check to make sure that in the process of moving a "hot" wire under the refrigerator did not come loose and now is contacting a metal part of unit.

U have a classic short circuit which accounts for the breaker popping immediately. It is not a short in the compressor because that would have popped the self resetting clixon and not the house breaker.

Apex ld3249 shot sparks out and tripped the breaker


A nasty short somewhere or wrong voltage to set---do not keep plugging it in and tripping the breaker--in fact do not plug in at all until a technician examines it(tell him/her what the issue is).

To answer the question here: Dead short on or across the AC voltage line inside the set most likely of primary side of power supply.

Demudifier worked great, all a sudden it just stopped. No power. Now it won't start up. What should I try?


First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

Hope this helps you solve the problem. Please let me know. Thanks.

My crown 602 xls tripped a breaker, I reset breaker regained power to receptacle , I lost power to the amp no led's come on front when i pushed the small reset button on the back I still did not regain...


They use a breaker instead of a fuse.

http://www.retrevo.com/support/Crown-XLS-602-Amps-manual/id/19050ci763/t/2/

CONDITION: No

power to the amplifier.

POSSIBLE REASON:

• The amplifier's Power switch is off.

• The amplifier is not plugged into the power receptacle.

• The amplifier's high-voltage power supply circuit breaker has tripped. Verify that the AC mains

voltage is correct, then press the Circuit Breaker button on the back panel.


Take it to the ER.

Need to reset circuit breaker


Hi,

  • 1 Turn off the light switches and unplug appliances in the room that has lost power.
  • 2 Find your circuit breaker box and open the cover.
  • 3 Locate the tripped breaker. Circuit breakers are small, usually horizontal switches labeled by the areas of the house they serve (for example, "kitchen," "bathroom" and so on). The tripped circuit breaker will be in the "off" position or in a middle position between "on" and "off."
  • 4 Reset the breaker by moving it to the full "off" position and then back to "on." That may clear an overload and return power to the room. If the breaker re-trips, you may have too many lamps and appliances plugged into the circuit; a damaged cord or plug; a short circuit in a receptacle, switch or fixture; or faulty wiring.
  • 5 Identify and correct the malfunction before resetting the breaker.



  • Please post your feedback and Vote if the problem resolved as per your satisfaction.

    NO POWER, POPPED CIRCUIT


    Two possible causes.

    First (and most likely) the circuit is being overloaded. This kitchen circuit may be shared with another appliance (like the refrigerator) which is drawing enough power when both are running to trip the breaker. A Typical kitchen circuit is 20 amp with #12 wiring. So an 1800 watt microwave might draw 13 or 14 amps while a fridge compressor kicking in can surpass 7 amps before it levels off. If this is an older home the kitchen may have a 15 amp circuit with #14 wiring. If the circuit is a 20 amp you will have to split the appliances onto separate circuits. (Under code a kitchen must have a minimum of 2 separate appliance circuits). If it is a 15 amp you might be able to split them as well or may be looking up upgrading the breaker and the wiring from 15amp #14 to 20 amp #12 (but you could still have the same problem).

    The other possibility is a short or loose connection. If splitting appliances onto their own circuits doesn't fix this you would probably want an electrician to come in and check for other underlying causes which could represent a fire hazard.

    Hope this helps.
