Question about Hitachi CM772 19 in.CRT Conventional Monitor

1 Answer

The monitor would not turn on. Only the orange LED does.

Hello there, I have a Hitachi CM776ET CRT Display. Since a week ago it started giving me trouble bending the image to the right and shifting it a little. The magnitude changed over time, so is was impossible to correct. Yesterday we experienced some brief power outages/surges/who-knows that made my lights blink and my computer shut down. I turned it on again, but the display won't. The display's orange LED would lit and there's a faint hum (like CRTs do), but absolutely no image (not even the message window that appears briefly when unconnected) and no degauss bang sound. When switching it off, there would be some untypical TV-off sound and the orange LED would quickly fade out. (normally it would take a little more time for it to fade out if the display is at stand-by after PC shut down.) I opened up the monitor, cleaned the (not too much) dust with an air-compressor and tested the fuse that I saw near the power plug with a multimeter device while still in place (was too deep inside) - It seemed fine, but the display is still dead. An alternate monitor *does* work with the PC. Thanks in advance, MK

1. Make sure the monitor cable is fully plugged into the computer. 2. If the new monitor works fine, The connection between the previous monitor and the PC was bad. Reconnect the original monitor to the PC and make sure that the connection is snug. Tighten down the video connectors until they are snug. Try again. good luck..

Sounds like you don't have a stable connection. Try shutting down PC, and disconnect the monitor, and reconnect it, and turn PC back on, then turn the monitor on...

Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Monitor is busted!

If your pc works on another monitor. I would recommend you buy a new LCD monitor or a used CRT.

The best solution if your computer works is to buy a LCD screen, I've thrown out my 17" crt screens they aren't worth anything these days. You can get a used crt from ebay

Over here where I live I bought a used crt for 25usd thats was over a year ago.

Theres really no point in trying to repair the screen if its broken, buy a working one or a brand new lcd.

Good luck.
