How to replace Sony monitor case

I would like to replace the cracked case of my working Sony CPD E400 19" CRT monitor with the case of a nonfunctional E400, which I just inherited. I don't have a clue how to open the intact case without damaging it. Please refer me to a link for Sony technical service manuals with drawings. I appreciate any assistance.

    Thanks for your answer. There only 2 screws on the bottom of the monitor case. I don't see any on the top. The case still doesn't open.

    Don't worry, I wouldn't plug in the monitor until the case is back in place.

I couldn?t find disassembly instructions for your CRT; however, I can give you some safety warnings and some general hints. If no one else posts at mine will either discourage you OR give you enough to start. First off CRTs are dangerous, taking one apart without the proper training and precautions can kill or severely injure you. If you don?t already have the training and experience discharging the stored energy in the monitor you should not attempt it even if you have ?instructions?. If you decided to continue on then there are typically four screws holding the back of the monitor case to the front panel. On some higher end Sony?s they are covered with a plastic cover that you can easily pry off with a screwdriver. Once you have them out then the back cover can be removed, exposing the tube and remainder of the electronics. Again a warning, unless you know what you are doing you run the risk of severe electric shock and should not proceed. Usually there are a series of screws that attach the chassis to the front panel, remove them, the panel electronic connections and the disassembly should be done.

    Even if you haven't had the monitor plugged in for a while there could still be a significant charge left. You simply have to discharge the capacitors before you can safely work on it.

Hi, My SONY CPD G420 monitor has suddenly stopped working - the front led is blinking amber. After power cycling the LED stays green for a few seconds before going back to blinking amber. I have verified...

just unplug the signal cable and see if it shows a warning! if it shows then the monitor is in some working condition! this problem mainly is not the monitors problem its the systems problem, it seem as if the system is in standby when u on it right??? it happens when the processor doesn't get supply or it refuses to come on! you will see that the red hdd load led will not light when u start the CPU; just open the CPU and unplug the smps from the board and blow the pins to clean them up and re-fix it and see it will work. if still it doesn't work try some other smps it will work! reply and revert back for more help with a vote!

Are you sure this is a monitor problem? I have a user with a Mac that occasionally has the same symptoms you describe. For me I generally have to shut the computer down and physically unplug the power cord from the computer (not monitor), reattach it and restart. Let us know if that works for you.
