I hope you can help! This monitor is less than 3 years old and a few weeks ago the menu for the monitor started popping up. I can't use the controls on the monitor to make it go away. I've tried unplugging, turning off and on, etc.
Sometimes it will stay on there for a long time, other times it will just pop up and then go away. The contrast bar is at 0 and I can't fix it
It just popped up again so I can't see what I had just typed. The contrast keeps flashing and the exit symbol keeps hightlighting (now it went away again). I've tried troubleshooting, but no effect.
Never a good idea to clean with any spray cleaner. The cleaner does get down in the button bar and cause corrosion and shorting along ribbon cable. Use screen wipes for computer monitors only on TV's and any type of monitors. You can remove the back of the case. And remove the button board and clean with a cue tip and alcohol along ribbon cable.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

It sounds like you have a monitor with a common problem. After a few years some LCD monitors
will blow a power supply. The problem is caused by parts called
capacitors overheating in the confined space of the monitor. If you are
good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work
fine. The capacitors do need to be installed with the correct + and -
connections, note the stripe on the old one and insert the new one the
same way. Look in our monitor repair section for step by step repair guide for this model. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
I hope this helps, if so please rate my solution.

A friend of mine had the exact same same problem. I think I fixed it, because it has been 2 hours, without the menu popping up. You need to open the monitor:
- Place it face-down on a flat surface
- Remove the cover of the hinge by gripping it with both hands and gently squeezing and pulling.
- Undo the 4 screws and remove the stand (base)
- Undo the four screws tha hold the cover down (4 corners)
- Use a flat screwdriver to seperate the 2 halves (I used 2, a small one to lift the back, a bigger one for leverage)
You will see a small PCB, fastened by 3 screws, at the bottom (where your menu+on/off buttons are) with a ribbon connection to the screen. Next:
- Unscrew the PCB, and gently lift it out.
- Clean the microswitches and the ribbon cable connection.
- Reassemble the monitor.
To clean microswitches and the connection, I used Kontakt Video 90 spray. There must be sprays on the market where you are. It's basically an alcohol-based cleaning spray. Good for cleaning video/tape/floppy heads, CD/DVD lenses, memory modules, etc.
it may just be stuck , if you push the button does it click like the others, a little wd40 around the button , lightly, may unstick it. or you have to take the bezel off and see if the positioning is the issue.
first of all you will to replace those buttons
as its useless after few years.
as per your problem is concern you might see some change after replacement.
still it does not work then there is a video problem
1 crt filament supply less
2 voltage on g2 is less .
3 check voltage on video ckt to be normal.
4 crt base loose.
5 there might be crt weak if it is old.
hope this will help.
Something is breaking down. Possibly a specific ceramic capacitor on the main power pcb that has been troublesome. Usually there is just a loud pop and the screen goes dead. If the set is less than a year old it is still on parts warranty and the technician could just change circuit boards until the problem is gone.
