Could the new main PCB and/or invert PCB be faulty or is TV completely waste of time? I replaced both main power & inverter or interrupt power PCBs now I have no power at all.
Had power before I got new PCBs. Was very careful triple check connections did not touch PCBs with hands or anything used gloves. Start to think I cannot solve this one

Liza-Maree; sorry all boards not created equal , you may have gotten faulty parts. Always make sure to ground yourself before doing this work.

A camper is usually fitted with two batteries and a split charge system that isolates the batteries from each other when the engine is switched off. One battery is the standard vehicle type and the other a leisure or semi-traction type to supply the low voltage caravan or camper fittings and appliances.
The caravan battery usually is recharged by a mains operated charging system that would be operational when an onsite mains hookup is connected and the charging/distribution unit generally has a helpful charge/battery state meter.
It is worth noting the output of integrated battery chargers is usually very modest and likely to be able only to maintain the battery charge when the 12 volt lighting and water pump/toilet flush is being used. Additional equipment such as audio, 12 volt tv and especially an inverter will discharge a battery in a fairly short time.
The laws of physics tell us we can't get something for nothing and that is especially pertinent when an inverter is being used. Commercial inverters make big promises; but drawing even a modest wattage can represent a relatively high battery drain - using a fairly ordinary colour tv on an inverter can take a 90 amp/hour battery down in a couple of evenings or less.
By power converter I assume you mean an inverter, a means of electronically/electrically generating mains level electricity from a low voltage source?
Siting, connecting and supplying an inverter depends a great deal on the capacity of the inverter, the expected load and the expected duration the device will need to supply current for the load.
The inverter instruction manual is the best guide.
Even though modern inverters are much more efficient, when working hard they still get hot and excessive temperatures and electronics don't mix so siting a unit so cool air can freely circulate around it is important and the greater the capacity of the unit and the greater the load it is required to supply the more important cooling becomes.
Providing the inverter with current is another difficulty due to the very high current consumption of them. When supplying a 1kw load the inverter could be consuming as much as 120 amps at 12 volts and that is enough to discharge a fairly large leisure battery in an hour.
It certainly is a bad idea to fully discharge leisure batteries or even traction batteries and it is best to ensure there is sufficient battery capacity to supply the demand without more than half discharging them. A constant high current drain will also cause the batteries to heat and while a warm battery tends to perform better it also shortens battery life.
Clearly in addition the electrical connections and the connecting cables need to be substantial and in this matter overkill is the best policy. Short connecting cables can be rated for the maximum current drawn but heavier cables are recommended for lengths of more than a few yards, especially if the cable is routed where air doesn't freely circulate. As a rule of thumb the cable diameter should ideally be doubled each 10 yards of length.
??.. You can get an inverter to supply 110 voltage..(or get a 12V TV).. what about reception?.. guess you could use an antenna... This is new to me... sorry..
I know it sounds corny.. this is the only place I buy mine from.. (3) ..they are VERY smart when it comes to knowing what you need,, just tell them what you want to do,, they will tell you how much "inverter" you need..
The gfi circuit inside is bad or was used for something pulling too many amps. Most in verters only use a positive lead and ground lead to power the inverter. If you can run another ground to inverter case just in case im wrong about the inverter. But, if I am right the internal rectifier is not swiching ground paths and is not completing a path to transformer for 110 volts, because it was used improperly.
it could have a fault and thats why it's blowing the fuse, inverters can wear out and the parts may need replacing the capacitors the voltage regulator chips all these parts have to be taken into account, this parts don't last for ever they need replacing. capacitors can last upwards of 12000 hours but electric jolt and what you are use to be powered adds more drain on the electronics most inverters you can get at most 5 years out of them but it really depends on what you use on them, and if you useing it to its max or near max all the time it will wear out, then blow fuse
Does adjusting the dimmer control for the dash lights have any effect on getting them to come on, or at least flicker?
The most likely cause is a defective dimmer control on the headlight switch. I've seen this on a few Chrysler models. The headlight switch and dash light dimmer is generally part of a single assembly, and is replaced as a complete module.
no you need to know the wattage of the item you are trying to power. To find the wattage of the item you are trying to power is simple. Some will say directly others will give you the amps (ie. .5amps, 1.2 amps.) you take the amps and multiply it by the volts that it says. All this info is on the item you are trying to power with the inverter. The answer is what it will take to power that item. example .5amps x 240v = 120 w so in this instance you would need an inverter that would produce at least 120w so in this case the 150w inverter would work. Good Luck, have a grt day
1.) You have a Bad LCD Bulb.. You can get a replacement LCD Bulb and change the LCD Bulb inside the Display which is cheaper and easier than replacing the whole backlight panel.... LCD bulbs cost around $12 Be careful these bulbs are Fragile and if bent when installing- will break...
2.) You have a failing Power Inverter... this is located just under the screen display panel,, it is a circuit board that the screens lcd bulb plugs into and the display cable plugs into... this inverter board converts the DC power in the laptop back to AC power because the screen needs more power to power the lcd bulb...
Your Problem Is One of These 2 Things... Your Best Bet Is To Test The Power Inverter First - Since It Is The Easier Of The 2 To Replace/Repair
