I am trying to get a power supply for a Poly View Lcd screen that I was given. The manufactures web site is of no use as it dosn't provide any real support like manauls or drivers ect. Can any one help me with this?
I do not have any part number which may be helpful.

wmtc348, If monitor screen is black, then most likely the problem is internal to the unit's "switchmode-power-supply/ cold-cahtode-fluorescent-lamp inverter power supply. You didn't state the "date of manufacture" from the rear of unit which is very important to give good better diagnosis. Do some reading in my (louie12fix) and (12fixlouie) Fixya profile and those of "budmrtn" and "buddymc" for more info on doing possible DIY or contracting out the repair work if unit is less than 4 years old. See if Viewsonic has a cash+old unit "swappout" program for your model. Also view some of the many DIY lcd monitor video clips that you will find on YOUTUBE to help you make "fix or trade for new" decision! DIY is $10 to $60 Contract repair is $40 to $90 depending on age and total hours of use unit has on it! Do some reading and view some videos first, before you do anything else!!! 12fixlouie
Is it that the when you power on the lcd monitor, the led power button powers on but no display? if it is, the means the picture board of your lcd monitor is malfunctioning.
It could be that the
board of your monitor has developed fault.
The best thing for you
do now is to take the monitor to a local repairer within your vicinity or any service center
to help with the replacement of the picture board
because the fault is not something you can fix yourself, in order not to
anthony_salt, If the fuse you replaced is still good, then I would first check the "switch-mode-power-supply" for bad electrolytic filter capacitors. By the way, was the original fuse bad? I also highly recommend you pay a visit to YOUTUBE, search out and view the longer vid clips of lcd monitor disassembly and lcd monitor repair. FYI try a website run by another fixya guy nickname is "buddymc" and the site is www.ccl-la.com/badcaps.htm They refurbish (rebuild) lcd displays of all kinds and all manufacturers. You can also check out these other sites FYI. www.lcdparts.net , www.badcaps.net I hope that this info steers you in correct direction. Good luck guy. 12fixlouie bye
lubbarlubab, Looks like you will need to get a power supply repaired/replaced in your unit. Before you call out the service guy, you should spend 30-40minutes at YOUTUBE and view some "LCD-TV repair" videos and also videos of "LCD monitor repair" and LEARN what are the most common components that are causing this plague of "BLACK SCREEN of DEATH" to disrupt your life. If the "cold-cathode-fluorescent-lamps" fail to light-up due to a failure of a single or multiple $2 parts on a power supply board you have a black screen!! This problem is also very common to LCD computer monitors. Try to view a vid by someone called "cal22583" who did his own repair to a Philips 42" or 50" unit. If this was of some help please rate on fixya.
Bye for now. 12fixlouie
rking3905, Please tell me if F1703 is BOTH BLACK and BLANK, or if it is just BLACK! If the screen is BLACK and you can see the WIN-desktop with aid of flashlight held 1" from the screen then the monitor's "switch-mode-power-supply" is in partial shutdown mode having detected a FAULT condition with the "cold-cathode-fluorescent-lamp" power supply called an INVERTER circuit (12vdc to 600-1200vac) to light-up the lamps hung on the rear of the LCD panel which produce WHITE light so you can see the image or text displayed on the LCD glass panel. In any case, you or a technician will need to evaluate the true state of your monitor. Also try to view some video clips on YOUTUBE that deal with "LCD monitor disassembly" and "LCD monitor repair". The longer (8-12min) clips are best. FYI goto www.ccl-la.com/badcaps, www.lcdparts.com, www.badcaps.net for more information on what may be the cause of your BLACK and or BLANK screen! If this was of some help, please rate this response on fixya.
The Viewsonic VX2235WM has a known issue with the power supply going out. The flashing power light or blank white screen are classic symptoms of this issue. Check out our web site at: www.ccl-la.com. We have a step by step repair guide posted that will guide to doing the repair yourself. It involves changing a few capacitors on the power supply. If you can solder then you should be able to do the repair yourself. If you don't want to do the repair we do offer a repair service for $35 plus return shipping. If you have any additional questions just let us know at: firstname.lastname@example.org
I hope this helps, if so please rate our solution.
You seem to have an oddball monitor if what you describe is correct.
The power supply to a monitor[Display Screen is that what you mean?] is either direct to main power- in which case the power cord is either built in with a power plug for wall socket,
or has a socket on the back for a separate main power cord.
Or is powered from a low voltage converter that delivers low volts usually via a coaxial plug like this illustration
PS2 connection does dot come into the equation as far as I know unless you have got hold of something unusual.
Tell you what take a shot of the back of the monitor and lets have a look see mean while here's is a shot of a typical low voltage power supply available anywhere.
