That's typical problem and often thought to be because of the cable, but it's actually the connector on the monitor. It's really easy to fix if you open the monitor and re-solder the connector... those pins just get loose by time. Just be careful where to touch if you open monitor... no danger around that connector though :)

Unfortunately, my knowledge of electronics doesn't extend that far. I bought an electronics projects kit with a breadboard in February, but I haven't managed to build even the first project, which is an LED with a dimmer switch. Some years ago, I saw a series on TV which included information that TV sets and monitors contain one or more components which store high voltages even when they're turned off and unplugged. This means that unless you know exactly what you're doing you can easily kill yourself by attempting to repair one.  The extortionate prices charged even just to look at a monitor to diagnose the fault prevented me from having it repaired.

to make the 1084s last forever you must do 2 steps

1: resolder all the board with good tin....(manufacturer used buggy tin in this monitor)
2: replace all those buggy chinese capxon caps and insert good japanese caps...ie chemicon, rubycon or panasonic

Thanks! This seems to be exactly what I needed to know. I couldn't do it myself, though.

This operation is way easier than you think. You don't need to know where you can touch, the connector is there so visible and easily reached. Hardest part is to figure out how to open the monitor case, but it isn't that difficult afterall. I didn't do any background work myself, just got the case open and then used soldering iron to melt the existing solder little.. I didn't even add any myself. Just touch with hot iron there on few pins and monitor has worked just fine after it.

I'm afraid I wouldn't attempt it unless I knew what components not to touch. Can anyone tell me what they are? Obviously, posting some pics would help.

As for my progress with this monitor, I finally got an audio lead and plugged it in, although I had some problems finding out which two of the four RCA sockets I needed to plug into. Using my A500 Plus and Relokick 1.4, I downgraded to Kickstart 1.3 , but then found that pressing a mouse button didn't switch to NTSC mode, just made the monitor flicker. I ended up adjusting the picture height on the monitor to avoid having the lower 56 lines blank. I played Barbarian by Palace, Lemmings, and some demos. I plan to try my Amiga A1200 with this monitor today and select NTSC from the boot menu.

Some more serious problems are the power lead and the on/off switch. The power lead supplied is very short and has been causing problems by lifting my extension lead off the floor. Last night, while sitting down on the sofa for a few minutes, instead of on a chair in front of the Amiga, I managed to accidentally pull the extension lead out of the mains socket! This turned off the monitor and the Amiga, but not the hard drive. I wondered what to do, but luckily I just plugged it back in and everything was OK. I wonder if there's anything special about this power lead or if it's just a standard kettle lead? As for the on/off switch, it seems hard to turn it off. I suppose this is better than not being able to turn it on, though. What should I do about this? I don't think just plugging and unplugging the monitor from the mains will do it much good.

Unfortunately, the monitor on/off button has started playing up! I found I had problems turning it on because I couldn't get the button to stay in the on position. Since then, I've resorted to leaving it in the on position and just plugging or unplugging it at the mains through an extension lead. Can anyone tell me of an alternative?

You could power it through a switched power strip....

Can you give me an example of this? Where would I get one? Can you post a link? The lead that came with it is also quite short and should be replaced. It also has to work on 230V 50Hz.

Common problem.  Jam it in with a paperclip and then just turn it on & off with a power strip, as mentioned above.  Or if you google, there's a million threads already out there on this subject:

http://eab.abime.net/support-hardware/67360-1084s-monitor-switch-fix.html

http://www.lemon64.com/forum/viewtopic.php?t=44403&sid=9e513b02c5ffb14b3f6da250ef76b6e8

http://www.amiga.org/forums/showthread.php?t=34385

Etc.

Second link has a listing to the Jameco catalog, where you can order a replacement switch for the whopping cost of $2.95, or use Cammy's awesome fix here:

A last solution would be to pick up a longer power cord, from somewhere like here:

Amiga 500: 2MB Chip|16MB Fast|30MHz 68030+68882|3.9|Indivision ECS|GVP A500HD+|Mechware card reader + 8GB CF|Cocolino|SCSI DVD-RAM
Amiga 2000: 2MB Chip|136MB Fast|50MHz 68060|3.9|Indivision ECS + GVP Spectrum|Mechware card reader + 8GB CF|AD516|X-Surf 100|RapidRoad|Cocolino|SCSI CD-RW

I've only just found this reply!

I've never heard it called a "power strip" before. To me it's an extension lead, which I'm already using. Most extension leads have more than one socket. To make matters worse, the switch on the wall socket is stuck in the ON position!

Suggest you don't use paper clips anywhere near mains electricity.

We call them power boards up in the south of the globe.  You can get them with surge protectors to protect your equipment. I always plug all my precious electronics through a surge protector power board (or strip in USA)
