White Screen I have a Starlogic 17" monitor that shows only a white screen after start-up. I assume that I'm only seeing backlight on the screen. Any ideas? Thanks.

Verify that the digital cable is pushed into the back of the LCD- IF that solves the problem put a piece of scotch tape over both the connector and the receptable so that they stay connected. Notice I said Scotch.. Not generic or Chinese cellophane tape - They leave too much residue, and lose stickiness over time.

Suggestion 2: verify that the other end is bottomed into the logic board.

Suggestion 3: press on the square Genesis chip - bad contacts and solder may be the culprit and TEST. IF so. you will need some flux, solder wick, and a low temp soldering iron. And reflow the solder on the chip (maybe 164 pin flatpak) after reflowing verify no shorts are between legs of the chip. You MUST use flux! there is no way around it. It has a purpose and will eleveate additional problems later by not using it. Then clean and remove flux with Q-tip and Acetone. (if using nail polish remover, get the kind without anything extra like Vitamin C, and Aloe) Pure Acetone is a good flux remover, Alcohol will have you rubbing all day, and still leave residue. (use in ventilated room though)
You should be skilled at this before attempting repair.


Suggestion 4 If none of the above works - the logic board is dead and may need replacing. The chinese company that made the board is hard to deal with, and the website is almost non-existant - http://www.hualong-hz.com/ and should be one of these boards http://www.hualong-hz.com/En_Product.asp?classid=30

Hope that helps

Why does my monitor have a white screen


First, it could be out of adjustment--turn the brightness and contrast controls up and down to see if it makes a difference.
You could have a bad video card in the computer. Do you have another monitor to try to see if the actual video output is good? This is the easiest way of troubleshooting.
When you start the computer, can you see any white printing on the screen indicating it is booting? Does the problem start once Windows starts? If so, try starting in safe mode. If you can do this, then I'd suspect video driver problems.

No Image on my screen but the LED is on


Use a flashlight and shine on your screen. Look carefully is you still see the image on the screen. If you do, this is an indication that the monitor is still working, but the backlight has failed. A common solution with backlight-failures is to open the monitor, and look if you see any "swollen" capacitors (http://en.wikipedia.org/wiki/Capacitor_plague). If you see one you should replace it. Only open your monitor if you know what you're doing and have basic knowledge of electronics and soldering.

I keep getting a full white screen on my laptop, how do i get rid of it


See if it is the laptop monitor by hooking up an external monitor. If that monitor works, your laptop screen has a connection bad that might be caused by the ribbon cable (if the cable carries the common), but given the symptoms, it can almost be assumed that some type of power problem exist with the lcd layer. The screen would be all white if the common circuit is open. The screen is white because the backlight is showing - because there are no darkened lcd pixels.
In all probability the monitor itself is not bad, it just has no lcd layer power. Another problem could be in the the video board where the output to the back gives power but does not power the resident laptop screen. Most likely it is a connection though.
If you are inclined (and it is out of warranty!), carefully disassemble it and start gently pressing connectors or wiggling (careful!) the cables. Chances are, the screen will try to work. Find the bad connection this way and burnish the contacts if needed, add contact grease (smathering only) and reseat the cables.

Monitor displays white screen when connected and powered.


You've done sensible substitutions and it does sound like dead monitor.
The white screen is due to no pixels being controlled at all; what you are seeing is an unpolarized view of the backlight.

It's conceivable that a power supply problem is at fault in the display since it is unusual to lose all control over the screen as this has done.
The cause has to be common to all of the drive circuitry in the monitor and sounds like a job for a tech.

9 months? Is the warranty coverage known?
Unfortunately, warranties seem shorter all the time but it might be worth a shot to locate and email an inquiry to the manufacturer.

Acer al1711 shows only a white screen


These are pretty old now but I'll respond anyhow-
When there is absolutely no screen content and white, it means that ALL pixels are turned off; black, means all are turned on. If you have a white screen, it means that a component in the video stream has failed; a black screen (preferable failure!) often means that the backlight lamp or its inverter have failed. The latter is a potential DIY fix, a dead IC in the video path normally not since most of the signal chips (ICs) are placed and soldered by robots and the pin spacing on those is pretty much beyond the capabilites of an untrained hand.
The only exception I can think of is if the ICs no longer have voltage supplied to them from the main power supply but you would need at least a cheap multimeter to locate that.

If you are getting a "No Signal" message, someone may have inadvertantly pressed the wrong button on the monitor. Use up arrow of button #5 below to cycle through RGB (normal VGA connection) and DVI sources. Down arrow will result in "No Signal" message.

There are five buttons at the bottom of the screen on this monitor. From the left:
1 - sound volume
2 - degausser
3 - power on/off
4 - monitor set-up
5 - RGB/DVI source

That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.
