Hyundai LCD monitor L70N Stuck in sleep mode?

Hi, I read these boards a lot... very helpful.
Monitor has black screen, and the power light blinks very very rapidly. I connected a good working monitor up to the pc, and it works fine... not the computer. I pulled the power cable from the monitor, and replaced it with the one from the PWS.. the PWS works fine, sooo cable not bad.

I read somewhere this rapid blinking light was indicative of the monitor being in sleep mode. So I hooked up a good monitor, went into power management settings, and its set to "always on".

OS is Win XP Home SP2.

How do I get the monitor out of sleep mode?

    when my computer goes to sleep mode anything that was on my screen is gone, thats how it is supposed to work. the light on the bottom is green indicating is still reading everything from the computer, but when you move the mouse to get your computer out of sleep mode i dont get anything on the screen. i have to turn off, and turn on the monitor about 20 plus times to get the monitor to stay on. very frustrating when you have to get things done in a hurry.

    Same problem!! My problem is sort of all encompasing with you yours, heres the basic facts of my monitor problem.

    L70N- Problem started (i think) once I first hit the SLEEP key on my keyboard to shut off quickly. Problems began small, have gradually grown to extreme frustration.

    I would have a black screen but green light was on. When i turned the monitor off (or the computer) and right back on the screen would instantly flash to the normal picture but go right away to black. Would constantly press on and off button on monitor to get it to work. Gradually it would take longer and longer. Replaced all cables, cpu and monitor power set to always on. Its taken me once 7 hours to get it working, I actually couldn't turn in a paper for my class but the professor said he had never heard this excuse and I guess atleast thought it was new and gave me a shot to email it to him. Obviously I wasn't kidding though.

    This week monitor has begun to rapidly flash the on/off power light, I just leave it and eventually once its solid I try to get it on. Since that has happened, it now reverts to some random resolution and I have to always change it to what I want before I can use it.

    Only way I can get it working is by letting it sit for an extended time without anything and when I reset the monitor power it works fine, I have to just reset the settings. I am determined to find an answer for this today, hopefully if I do I will post a way to fix it!

I'm not sure if this is the solution, but something happened. I plugged in the monitor one last time before I was going to throw it out. I plugged in the power but left the VGA cable unplugged in hopes that I could get into the menu screen of the monitor itself. Well no amount of button pushing helped (but I did do it) but after about 20 minutes I came back to it and it was on. So I am really not sure if it was some button pushing or just a default for being plugged in (power) and no input (VGA). Now I'm off to apply the new driver.

My Hyundai L70n monitor periodically displays a thin vertical yellow line on the left-hand side of the screen & I can't get rid of it. Please help me understand why.

That is a problem with the memory array in the monitor. If it is under warranty, don't even mess with it. Take it in. Otherwise open it up and exercise all the connectors on the logic board inside. That works about 30% of the time. If that does not fix it, then it is terminal. They are so cheap now that it doesn't even pay to try to get the repair parts. They will cost more than a new one.

My hyundai imagequest l70n lcd monitor started to started to make a high pitched noise and the screen went black but the green light stayed on but now i plug it in and nothing happens no picture and no...

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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:

Power on and monitor goes to sleep mode

You need to try it on another PC, alos verify if the VGA cable is good. If nothing change, then you need to open it up, first thing to look for are the capacitors in the power supply. Look for cpas with bulging top/seal, see example of failed monitors here:

Monitor screen is like in sleep mode. It has power, but it won't show anything.

candlelig840, Your "cold-cathode-fluorescent-lamp" back-lit lcd monitor may not be in sleep-mode!! However, it may be in "black screen" or "Blank n Black screen" mode. Spend an hour doing some reading in my fixya profile and read testimonials and follow the web links. Your monitor isn't any different than any other brand in it's basic design and operation!!! Again, read my and other LCD monitor tech's ("budmrtn" , "buddymc" ) for information on doing your own repair or to find out all your options you have when dealing with CCFL back-lit LCD panel that is now black and lifeless!! If you live in or near a large (>2 million) city, give a call to local TV/lcd repair shop and question them about black screen and what is the top cause of lcd monitor/ lcd tv black screen failures. If you need further assistance after you research your monitor's problem do another comment here on fixya and we will be glad to help you. Do not rate this response. If you do, you will break the link and not have option to do further comments back to this posting. 12fixlouie

Screen went black with power button blinking instead of being solid...what gives? Its almost like it went to sleep mode but when i move my mouse nothing happens.

cklein95, I should guess that the unit's "switch-mode-power-supply" is in full or partial shutdown mode. Check all cable connections. Then read a few of my longer responses to BLACK SCREEN lcd owners to find out all the options you have when faced with a LCD monitor that has failed prematurely. If unit not covered by warranty, you will need to decide if you are going to trade-up for wide-screen or contract out for repair or you will go on DIY repair quest. Follow the links to other sites listed in profile so that you will understand the no.1 cause of BLACK SCREEN. Do you know the lcd flashlight test? Do you know how to unsolder and solder parts on a printed circuit board. Do you know how those new energy efficient curlie-Q CFL light bulbs work? Hope this gets you started. 12fixlouie

My Monitor

Ok? first what you need to do is to hibernate your computer. You can do that by pressing the power button as long as you need for the computer to turn off. Then you turn your computer back on and press the power button ON THE MONITOR twice but you MUST do this really fast. Then what you need to do is to find a circuit breaker on the back of your computer. switch it to the off position then turn it back on. Then turn your computer on. This should fix your problem.

Stuck in sleep mode w/black screen

If possible, try a friends monitor first. If it works, you can then change the sleep mode setting so that it won't come on again. If the other monitor does not work, the video card is probably defective.
