VP171b : white screen problem

The monitor(VP171b viewsonic) was working fine. Res: 1280X1024 60Hz. suddenly the screen became white. after repeated power on. the screen display came back and faded away. Looking from tilted angle the screen appears to show graphics when turned on but slowly fades to white screen in few seconds. What could be the source of problem? is this fixable? thanks

SOURCE: Picture goes out after 1 second, audio is fine

the problem is not the mian board but the DC to DC inverters that drive the lamps behind the panels some manufactures make them available seperate from the panel but most are a part of the panel. so the whole panel may have to be replaced.

SOURCE: When I turn on the display, the ViewSonic logo

this is my problem too. i called viewsonic and explained my problem. They had me send it in. after waiting over a month for them to fix it, i recieve it in the mail. Out of the box i plug it in and turn the tv on and THE SAME EXCACT PROBLEM IT HAD WHEN I SENT IT IN HAPPENS AGAIN. It started doing this again. My solution would be not to buy viewsonic monitors/TVs. They never reply their emails and overall their service kinda sucks. sorry. There may be an easy fix to this but apparently the numerous people i talk to on customer service don't know how to fix the problem... BAD SERVICE

SOURCE: viewsonic n2750w turns off half a sec after power on, still sound

I had the exact problem with an Acer P191w monitor. After only 2 months of light usage, it would power up and show a beautiful picture (my desktop from my pc) for about 2 seconds and then only a black screen. I was about to send it back to Acer when I tried resetting it. That solved the problem. I know how to reset an Acer, but I'm not sure how to reset a viewsonic or even if that would work. I think the viewsonic reset procedure is, monitor plugged in but power off, press the front panel "channel up" and then the "power" button. As the monitor powers, keep holding both buttons in until "All Reset" appears? If that is not correct, perhaps someone with more experience with viewsonics can offer more help. The power supply capacitors are definitely a big issue. But this may work for you. If so, it's an easy fix.

SOURCE: ViewSonic VT2230 turns on, shows

Hi,
This kind of problem related to bad firmware saved in ROM that is part of main board so main board will be rpelaced to solve this issue.
It has nothing to do with power supply board that was replaced.
I'm not sure if main board is available some where as I could not locate it.
Thanks.

if it is completely white then this sounds like an internal connection problem. If the monitor is under warranty have it repaired through viewsonic under warranty. If not I would still recommend you have it repaired as unless your very confident in your ability you don't want to do any further damage. If you need any further assistance please let me know.
Thank you,

I have a Viewsonic flat-screen tv, it displays "menu locked" ??


Try holding the VOL + and VOL - buttons on the TV (not on the remote) down together. You should see a "unlocking buttons" message on screen. This might work. However, I tried it repeatedly, as told to by the Viewsonic "service" rep, and it didn't work for me. Viewsonic is ****, and so is its "service"!

My mointor turned purple


Now this may or may not work for you.

I think I had the same problem today, I just turned on my PC and the letters and startup screens were purple all of the sudden when the day before they were just fine. Well this is what I did to fix it.

Your Monitor should have some buttons below the screen. You want to press the button that says
"Menu". Once on the Menu screen use the up & down buttons on the monitor to scroll through the menus. What you are looking for is a "Reset" option once you find that choose to reset the Monitor and all the colors should go back to normal.

I am sorry if it is hard to understand, I did my best to explain it. I just hope this helps

Good Luck

VGA hookup to my Toshiba Satellite


Set the TV input to PC (that's ViewSonic's term for the VGA port).

Setting the computer to output to the PC may depend on your OS (XP, Vista). Reboot the computer after connecting the monitor and see if new hardware is found. Reboot again if you have a flickering screen. In Vista, right clicking on the desktop brings up various video and desktop options. Choose Screen Resolution and look for the multiple monitors line. Click Apply and OK after setting your desired output. In the Screen Resolution window you should see two monitor boxes (labeled 1 and 2) if the computer sees the monitor.

If the second monitor is not showing up (no new hardware found), check your BIOS and device drivers to see if you need to enable or update the drivers for the VGA port. Check your manual for the BIOS (often it is click F1 or F2 before the OS loads; it's often tricky timing and I have to try repeatedly). Device manager will have a red x if the port is disabled; the exclamation point (yellow triangle) indicates driver issues.

I realize this is nearly a year after you posted your questions but I hope it will help the next person searching for answers on this TV.

Viewsonic n3251w will no longer display Closed Captions


You can reset your viewsonic remote control by removing the batteries, and holding the power button down for 10 seconds. Just 10 minutes ago I repaired my remote, which was doing absolutely nothing, not even turning the set off and on, Called Viewsonic, they told me this, and it worked ! Yay !

Nick in LCD screen


If it's a stuck pixel, give it a sharp, firm tap with your fingertip a couple of times... this will make it go away for a while.

I have one on my monitor that is stuck on blue and this works.

You need the upgrade kit - make Sears come out and order it for you - they know all about it, claim that the monitor should have been recalled. Mine was out of warranty, however I convinced them to fix the TV.
