Check for fuses connecting the inverter. There are typically two visible on the exterior (20 or 30 amp blade style). If either or both are blown, you will get faults. Something else you may want to check is the incoming voltage. Power surges and voltage drops in L1 or L2 of the 50 Amp shore power could also give inverter faults.

Looks like you have a shorted IC ot transistor on the LCD layer of the panel.
If you remove the screws from the back of the panel and look underneath, you will see the circuit the main board plugs into. Usually there are a few components on this pcb that can go bad. Replacing them is a little hit and miss. If you can identify the component, you might stand a chance. I had a unit do this, and when I looked at the lcd pcb there was a shorted smt transistor. It was burnt, but I was able to remove it without damaging the board.
I managed to replace it twice with two similar transistors, but the panel still caused the power circuit to cycle when I plugged it in. Although I couldn't find any other shorted parts, the small smt ICs on the board could have had internal shorts, or the transistors I used to substitute were completely wrong for the circuit. Since the original transistor was burned, I could not identify it in any way.
The only hope for your monitor is to identify and replace the bad smt component on the LCD board, or replace the lcd layer itself. I've done this a few times, but it requires another of the same panels, one with a bad backlight perhaps. If you are careful enough, you can remove the metal frame assembly from the panel (there are usually four screws, two on each side). You will have to "unsnap" the outer frame from the inner frame all the way around the outside.
Do this to both panels, and place them face up on a desk or bench. Carefully unwrap the ribbon cable and remove the entire lcd layer. Do this a second time, only place the working lcd layer over the working backlight assembly. Make sure the lcd layer seats snugly in the frame and wrap the ribbon cable over the top. Reinstall the outer frame. You have to make sure everything stays aligned as you snap the outer frame back into place. Reinstall the screws. Now you should have one perfectly good lcd panel. Keep an eye out for a panel with a bad backlight.
SOURCE: 2001 passat has loss of power, shaking and check
i had this problem on my 2002 passat. it was the ignition coils. first set were replaced in 2002 as a vw recall. second set (at 122K miles) were relatively inexpensive to fix. just one failed but it made the engine run really rough - my mechanic was able to move it from one cylinder to the next to get the problem to repeat.
SOURCE: air conditioner tries to start but kicks back out
Hi. are you saying that the unit tries to start up....do you mean the compressor only or that the unit does come on fan and all, runs for a short time and shuts off completely?? I just need to no what it is doing on start up before it kicks out, this would be very helpful in solving this for you. If it trips the breaker or not or does anything at all run for a second. Please let me know and I can have a solution for you. Thank You.

You have to get hold of a test light and start checking fuses and wires for power. Check relays.
