Question about Dell UltraSharp 1800FP 18.1" LCD Flat Panel Monitor

1 Answer

Intermittent power on problem, monitor now completely dead

This monitor had an intermittent power on problem. I took it apart to see if there were obvious issues such as blown fuse, burnt or blown device, bad solder connections on power connectors, etc. Found nothing obvious but before reassembling I had plugged it in to check output voltage from the power supply; Got 12V and 5V output from output connector, however, the led on control panel lit up and viola, the monitor worked. It continued to work for about 3 weeks until I had to replace the surge protector it was plugged into. Once it was plugged in, it wouldn't turn on. If I unplug it then plug it in to the live outlet, the status led (green on, amber idle) flashes very faintly but it does nothing else. I'm pretty sure the PS is good. If it is, then what else could be causing it to not turn on.

My 2011 Dodge Grand Caravan won't start; the message was "No Fuse". How do I figure out which fuse to replace?


You can remove each fuse, one at a time (making certain you know where you took it from each time). A bad fuse will be obvious. The metal inside will be burnt apart instead of looking completely clean. Your bad fuse may take a while to find. Your owner's manual tells you where EVERY fuse is located.

Benq FP92G screen blank, power lit not lit either. Tried different cables but still the same.


More likely to have power supply problem, that will be the first place to check, look to see if it has any caps with leaking/bulging tops/seal, burnt spots, shorted transistors in the backlight inverter board, cold solder joints. Look at my DELL albums (BenQ made a lot of monitors for DELL). Be real careful when removing the front bezel, you can easily rip apart the cable.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Same thing.


Hello,

If you have the 2 blown capacitors on the power board then most likely yo also have blown MOSFETs and a blown fuse. The MOSFETS and fuse blow when the capacitors short out when they blow. We sell a kit with the capacitors, MOSFETs and fuse with instructions for $10.00 plus shipping. Let me know if you need a repair kit.

Gateway fpd 1960 goes black intermittently


Your inverter is dying. It produces ~2k volts for the ccfl (cold cathode fluorescent lights) that surround your display. At a few milliamps. Probably bad or leaking capacitors on the inverter or power supply board. So it is either using too much power (bad ccfl) or a weakening power supply (higher likely).
It could be cold solder connections becoming intermittent. Remove the base, remove the screws on the backside, and split the case CAREFULLY. Inspect the power supply and inverter for obvious failure or leaking capacitors. Replace same... If your lucky, it will work.

Monitor isn't working


just replacing the fuse should help. There are two of them on the inverter board. depending on which one is blown will give you 2 different issues. One will cause the screen to flash content perfectly for two seconds and then drop out. the other will be really dark if can see any picture at all,
