Common failure in this TV is the caps in the power supply are bad and also failed 5VDC standby supply stops working (if you do not see red indicator light on the front panel, the it is bad), and backlight inverter bd.

Outlets not working all fuses are good


120-
VOLT
AC
SYSTEM
The following electrical components (if so equipped) will only operate when your
RV is connected to shore power: 120 to
12-volt power converter, air conditioner,
120-volt refrigerator, microwave oven, television(s), fireplace and appliances
plugged into convenience receptacles.

SECTION 6 - ELECTRICAL SYSTEM JAYCO TOWABLE
6-2
120-
VOLT
CIRCUIT
BREAKERS
The 120-volt AC circuit breakers located in
side the main load center protect all
120-volt wiring and components in the RV fr
om circuit overloads and short circuits.
Should a circuit overload or short circui
t occur the circuit breaker protecting the
affected circuit will "trip" preventing the flow of electricity through that circuit.
If a circuit breaker trips, shut "off"
the appliance on that circuit (i.e., power
converter etc.) and allow the circuit breaker to cool down for a brief period of time.
After the cooling down period, reset the circuit breaker by moving its lever "off" and
then back to the "on" position. If the circuit breaker re-trips or frequently trips,
contact your dealer to have the electrical problem diagnosed and repaired.
A circuit breaker identification label is permanently attached to the inside surface
of the 120-volt load center.
Maintenance and Replacement
At the beginning of camping season, inspect the circuit breakers and replace as
needed. Test by turning each circuit breaker "off" and back "on". Circuit breakers
are wearable parts and must be replaced
as needed, as part of your RV
maintenance. If you have any questions, consult your dealer.
Please contact your dealer for repair assistance when replacing circuit breakers.
CONVERTER
The power converter converts 120-volt AC power to useable 12-volt DC power
when the shore power cord is connected to an external power source.
The converter has a built-in protective thermal breaker that will shut it down should
overheating occur. Overheating can be
caused by operating the converter above
its maximum power output for an extended period of time, or by an obstruction to
its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt
lights and motors turned "off"
.
Keep the converter cooling fins and fan clear of
obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged)
check the reverse polarity fuse(s) in the converter fuse panel.
There are no
customer serviceable parts inside the converter case and the
manufacturer's warranty will be void if
the case has been removed
. If you
have further concerns contact your dealer.

Viore tv won't power up after power outage.


I would first test the outlet. Unplug the TV and plug in your vacuum or other loud or bright object. Turn on test object - if there is no operation, then you have a tripped circuit breaker. Find the electrical panel ( Grey box mounted into a wall, usually in a closet). Find the tripped breaker ( typically the switch will be halfway between on and off, and many have a red indicator by the switch base). Turn switch to off fully, then back to on.
Retest outlet.
If still no power to outlet, unplug everything from that outlet and call an electrician - there may be a serious problem with the wiring!
Hope this helps!!

Don't have power to 120v recpt. on dometic rm 2862 ref


Go to your breaker box inside the RV. Locate the breaker that is for the refrigerator. It may have tripped but still looks as if it is on. Turn it off then back on. It should click and stay firm in the on position. Now check your outlet for power. Either use an outlet tester or a portable radio. If you have power but the refrigerator is still not working you will also need to check the 12vdc power supply. The refrigerator must have 12volts to operate even when in AC mode. There is a wire from the 12vdc connection block that goes to a thermal switch on the heat riser tube to the right. That wire has an inline diode and if the diode has failed it will not allow the refrigerator to work and like wise if the thermal switch has tripped it will shut the unit down. The switch is resettable. The diode wire, if bad, will have to be replaced. If you do not have 110vac power at the outlet after resetting the breaker you will need to remove the outlet and inspect it for bad connection or broken wire and then trace the wire back to the breaker box until you find the point of failure. You will also want to check the ground bar in the breaker box and make sure the neutral wires are properly seated and tight.

Our window AC unit stopped suddenly. Completely dead. The outlet has power. It's a 220V unit. LG window AC LW2510ER Any advise what it could be? Does it shut down when it's 100F outside? Thanks...


No - the outside temperature will not shut the AC down.
You say the outlet has power? Does it have the needed 220 volts? Most of the time 220 volts is on one switch, (that operates both 110 volt legs of power at the same time). - but sometimes each leg is on a separate breaker and if "one leg" trips you will still have power at the outlet (110 volts) but you won't have the needed 220 volts. While this is not likely - it is possible - so I would want to test the outlet with a voltage tester and determine the voltage. You might try checking in your breaker box and seeing if another breaker (110volt) is tripped. The same thing applies if you are dealing with fuses instead of breakers - determine the voltage at the outlet - and if you don't have 220 and only have 110 then look for a blown fuse or as I said above - a breaker tripped.
If you do have 220 at the outlet and nothing is running - I would be looking for an inline fuse of some sort within in the unit. Many of the newer units have them and they are usually easy to spot and all you have to do is to unscrew the fuse holder and replace the blown fuse. Be sure to have the power off when handling fuses.
Note: Be aware that while breakers/fuses can trip and blow without a serious problem going on - they (blown fuses/tripped breakers) are usually a sign of something significantly wrong with the unit.
Good Luck!

I opened my fridge to get something out, shut the door and EVERYTHING WENT OUT??? No lights, no nothing??? I tripped the breaker and checked the cord etc... Nothing????


Make sure your getting power at the outlet by pluging in somthing like a hair dryer. If your getting power at your outlet then you probably have a controlboard problem.

If you don't have power then first look for GFI RESET in the kitchen. or fuse box.

Tv will not turn on


You lost the standby 5vdc power supply and may be a lot of bad caps, very common problem with this model.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

Pushmatic breaker keeps tripping everytime I hit


You have it shorted out somewhere along the line. If it is a light switch you are switching, what have you done lately to make this trip? Anything? You might have a bad breaker. You can check it by shutting off the power, pull the wire out of the tripping breaker, put it in another breaker, turn the power back on, switch the breaker on, then hit the switch and see what happens. If it snaps off, it is not the breaker, but the switch, the wires in the box, or the lights, or something along the line, you will have to check each one. New construction has made all lights and all receptacles separate, so if your house is old, you might be looking at receptacles too. Check anything plugged in to an outlet, make sure there is nothing shorting. Hope this helps.

I have a circuit breaker socket in my kitchen. Connected to it are two coffee pots and a Microwave. Periodically it trips for no apparent reason. Usually when there is only one appliance operating. ...


First make sure the connections to the fuse box and to the outlet where you have the appliances connected are clean and tight. If they are, next you you might want to replace the circuit breaker with a new one with the same Amp rating. You also have to see which other thing are sharing the same circuit. To do this turn off the breakers one by one if you don't have them labeled, and see which rooms or which other appliances or units stop working which are also turned off once you turn off the breaker that has been shutting down. If there are other things connected to outlets which are sharing the same breaker, not only in the kitchen, but in some other outlet in the kitchen or even some other room, then it could be that some other appliance or heavy equipment might also be draining too much power from a single breaker. Check and see how many other things are turned off somewhere else when you turn off that particular fuse which is shutting down. Hope just replacing the fuse will take care of your problem. If what I have suggested does not do it, then just call an electrician to check it out. Be careful! Hope this helps. God Bless.
