Re: Gateway FPD 1830 LCD Monitor
User "noclew1" Your problem is the back lights are not being powered. There is a signal going to your FPD because the power light remains on, but the back lights are what helps support an image from the Front Panel Display. The only way to fix this is to open it up.
If its got 3 boards inside((logic-->video, Inverter, Power)) The problem is the Inverter. Replace it. If its got 2 boards inside ((Logic-->video, Power)) The problem is the power supply. The inverter is embedded onto it.
Simply replace the part with a known good one, and you got a spanking new monitor.
As for User Guest
Your issue is nearly the same issue when it turns off on you. But the doubling effect is from the power being supplied by an old or weary power outlet to an FPD. That can be the cause. Try different locations.
Well I wish you both luck and I hope this solution can help you with the problem. Thanks Victorsinferno45

The power supply, the inverter, or the lighting tubes may be defective. I would bet that you need some new capacitors in the power supply or possibly some transistors. Those are the two main failure points that cause the quick power supply shutdown. It detects overload and tries to save itself from total destruction by shutting down.
I bet on capacitors, especially if you never turn the power off but let it sit in standby all the time.
The problem is that the "LCD-inverter" part inside the unit has failed. It's a $20 part to replace, but I recommend that you pay a certified technician ($50?) to disassemble the monitor, replace the part, and reassemble it.
Usually in these cases the power supply would be the issue, but you say the OSD window shows up clearly, So the LCD panel is good and the Power Supply /inverter depending on which your FPD has. FPD 1830 should have 3 boards(logic, Inverter, Power) otherwise just 2(logic, power)
If it is super dim, the problem is the inverter. Or the Power Supply if the inverter is embedded
Otherwise what your issue is the logic board, if you can swap out that part for a good one, Chances are for sure that you will have a spanking new FPD working.
I've worked with these a lot. Im working on one right now. I hope this helps Wish you luck Victorsinferno45
After usual overheating the capacitors, the weakest spot in FPD1830 are
four chip resistors located in the inverter board a bit above the
middle, you can recognize them as they are bigger than others and
located all four in one row. Holding by tweezers simply re-solder them
to get rid of micro-cracks in the tin between pads and resistor
