20 Most Recent ViewSonic VP191b 19" LCD Monitor Questions & Answers


Hello


This is not a power cord problem. This is a problem on the powersupply board of the lcd. There are a number of electrolyte capacitors that are most likely going bad and would need to be replaced.


Safest bet would be to replace all normal sized electrolyte capacitors on the power board of the display to get it to function like new again.


If you don't own a soldering iron, any local vcr/tv or such repairer should be able to fix the problem.

This is common with this model. The switch mode power supply is not starting up when it is switched on. This supply creates 12VDC to operate the monitor. It could be the IC, a resistor or a capacitor in the start up circuit.

If you went from a standard screen to a wide-screen, you have to upgrade the video card.
Also, try going into the menu option on screen and have it automatically detect settings.
First thing you should do is update your drivers.
Should have said that first.

sounds like your inverter is going out. It is pretty cheap to replace if it is modular, ie. if it is a seperate plug in pc board. I parted out a 19 LCD because the inverter was integral with the power board and was not economically practical for me to repair when new ones are 169.00. also look a the capacitors (look like little cans with crosses on top) on the pc board. If any have bulged or blown their tops, you can try to replace them at about .50c a piece and a slodering iron. Just get the correct value, voltage (higher is OK) and temp rating (higher is OK too, but they are probably 135C anyway)

Seeing the word "analog" on your screen means the monitor has recognized video input on the vga "analog" input connection.
Most computers output "analog" vga (15 pin) which must be converted to digital for a flat panel monitor to display the image.
Many LCDs now have both analog and digital inputs.

It?s possible the shop may have been right. From your description it sounds similar to problems I?ve had on a few computers in the past; in fact I have one I need to test on Monday morning as well. For me this has usually been a video card/driver problem, I suggest you connect this monitor to another PC. Some LCD monitors have a video cable that is removable. If yours does make sure you use another cable you know works and not the one from your PC. If the problem follows the monitor then I would take it back ask for the manager and try to nicely convince him/her that this repair should be under the warranty since you had brought this to their attention while it was in effect. If the problem doesn?t follow the monitor then the next thing to try is connecting another monitor to your PC to see if the problem reappears. If you can?t do this then the only other option is to assume the problem is your computer hardware or software. - Remove the video cable where it plugs into the PC and check it for bent pins, corrosion; replace and firmly reconnect using the thumbscrews on the connector. - Some LCD monitors have removable cables some don?t; if yours does follow the same procedure outlined above. - If your monitor has a removable video cable try switching it with another one you know works. - Find, download and install the latest driver for your video card, restart and test. - If your video card is not built into your motherboard then remove and reseat the card in its slot and test. - Try another video card in your PC. Tell us the results and please let us know if you have any other questions; thanks in advance for rating this posting.

You need to change down the res. to a minor mode. i.e. 800x600 low quality. For Windows enter the protected mode - i.e. after POST (bootup) press F8 then enter with your account, or the administrator. Right-click anywhere on the empty desktop and enter "Properties" menu. Turn the screen resolution down in there (i.e. 800x600); also, check whether your current monitor is recognized by model in there. Re-adjust to a suitable working resolution. If all fails, you can also de-install the video card driver in admin protected mode to go back to basics. Of course You need to re-install it again afterwards when in your original Windows.

hi if your sure that all the power settings of the screen and the comp are fine then it points to 1 reason: the screen is heating up and the automatic circuit shuts it down... try locating it some cooler place or put a vent behind it... see if it does any help if soo set it in a cool place good luck

Hello Edelberto, this monitor does not disarm by the back to disarm the monitor, you have to remove, with great care, the front frame and there you will see the obstacles you have to remove the panel assembly and the platelets
I hope you can disarm it, comment the results

It is more likely to be a problem with your video card or on-board video. The only way to check is to connect the monitor to a laptop or another computer known to work.
