SOURCE: New 19" flat screen monitor only shows analog on the screen

finwiz,
When you on your computer, does any thing appear on the screen, some text display/logo etc.?
If yes then:

  • After making power on your computer start pressing F8 till boot option menu appears.
  • Then select safe mode and if it works, then goto device manager and re-install driver for your display.
If no then:
  • Check out the connection from monitor to computer and try. If still no luck then post comment whats you did and what was the result.

Thanks
Iqbal

SOURCE: Black Flat Screen, sometimes works for a second

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's most likely the problem. You can confirm that it's actually the monitor and not your computer or the cable by plugging in another monitor if you have one to try. If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old your monitor is, and how much you've invested into it, you may find it better to just replace it with a gently used one from ebay.

SOURCE: I have a soyo computer monitor, flat, 19

packldr, If your certain that the monitor is not going into sleep mode, you will need to find out where the possible bad solder joint might be. This type of symptom could be a "intermittant thermal fracture" of a solder joint on an internal printed circuit board inside your monitor. Your monitor works fine until the internal temperature rises enough to cause "thermal expansion" to cause a OPEN connection on some critical component on a "switch-mode-power-supply" or "cold-cathode-fluorescent-tube" power supply circuit. (INVERTER ckt) If you visit youtube, check for videos that deal with "LCD monitor repair" and "bad capacitors", "LCD disassembly" just so you know what you are dealing with. Please let me know if this was helpful to you. I'm louie12fix on fixya or lmistyrel@aol.com Bye for now.

Hi I have a problem with my Toshiba regza 52Z3030D, on start up the screen has double vision and lines that go from right to left


It sounds like you have a classic either horizontal and/or vertical drive problem. This is definitely a "take it to the shop" problem. Nowadays it can be either a hardware or a software problem. If you're using it as a computer monitor it could be a faulty video card or corrupted driver.

I double clicked an icon and the screen went black.now on srart up the screen goes blank after power saving mode


Try it on another PC first, if it still does not work then you will need to open it up, most failures are in the power supply section due to bad caps (leaking/bulging tops)

Have you tried to substitute a different cable? Many times a cable can go bad, and you cannot tell, because of how they are made. Get a different cable to try as a replacement, and see if that doesn't resolve this issue.

The task bar along the bottom of the screen, I can't see it


Adjust controls on the monitor. There a double box that lays on top of the other. Adjust that option... You may also want to adjust the setting that shows a box with arrows pointing up and down. adjust it as well.. Experiment on the settings. You'll get it right.
