Question about Proview PL926WBi 19" LCD Monitor
I had problem with a Proview 19? monitor: Product number: #PL926Wbi Model Number: 900W The monitor was manufactured in January of 2006. After I had owned and been using the monitor for 1 year and two weeks, it started having problems whenever it was first turned it on from a ?cold start?. The monitor would just turn white when first turned on sometimes it had grey vertical lines. After letting it worm up for an increasing length of time, either rebooting, or changing screen resolution would make it behave correctly. (I was using it as a secondary monitor connected to a lap-top computer). Eventually, the monitor would no longer reset, and I set it aside and put a new monitor on. This weekend, I decided I needed to fix it. To perform this repair you will need to know how to use a soldering iron, screwdriver, and purchase Capacitors to replace the ones going bad in the power board for this monitor. Here are the steps to repair this if you have the same problem. 1. Remove the four Phillips screws on the bottom of the bezel. 2. Flex the Bezel out away from the flat panel and slide ?up? to release the catches on the Bezel, 3. Remove the six screws on the sides of the LCD. 4. Lean LCD away from the electronics inside and disconnect screen cable and four backlight cables (2 bundles of two, and a big flat connecter) that are connected to the metal box directly behind the screen. The box is the electronics cage. 5. Remove the screws from the top of the electronics cage, and peel back metallic tape sealing it. 6. Remove top of electronics cage. 7. Remove the screws holding down the power board. (The board on top with the Black plug sticking out of the monitor bottom for the power cable.) 8. Unscrew the grounding strap. 9. Buy six 470uf electrolytic capacitors 9The ones in the unit were 25v Radio Shack had 35v for $1.69 each) Remove bad capacitors, replace with new capacitors (the black half of the circle is where the stripe goes.) 10. Reassemble in reverse of disassembly. On my monitor this restored functionality (It has been running for 1 day), so for about ten dollars and an hour or so of time, I got the monitor back to where it appears to work like new. Your mileage may vary; good luck, and good night.

Wow. I'm surprised by how many people have had this problem. My Proview 22" goes white and the blue led blinks when it flickers from white to black and stays white. It would take several reboots to actually get the screen to work... and how long it will stay working is unpredictable. I've contacted Proview support via email and I'm waiting for a reply. I see that people have done the repairs as mentioned with success and I'll be doing the same soon! I"ll post the outcome when I get around to do it.
If you're wondering, mine:
product no: PL926Wbi
Model no: 900W
Manufactured: January, 2006

I had this same problem the day after a severe storm. When I opened the monitor I noticed that all six of the 470uF caps were bulging @ the top and two had black ooze seeping out of the top.
I followed the instructions by Delphiuser and they worked perfectly. Also, the tips by macSPT were extremely helpful, especially the one about numbering the back light cables! If you follow these instructions, you can't mess up.
I'd like to add that you will also need a small pair of diagonal cutters to trim off the cap leads after you solder them into place. In addition, when you go to Radio Shack, get the radial lead caps, not the end lead ones. The Radio Shack part # is 272-1030 and they were $1.29ea.
This was an easy fix to make and saved me a lot of money.

Just wanted to add- I just ordered these on ebay, auction #120369102130. I got twelve for 5.35 delivered. I hope this solves my problem and this imfo helps someone. Thanks

I've got a Phillips X19 Monitor basically the same as the Proview screen 900W. I've just tried this fix and its not working for me. The problem i'm having is when you turn the screen on, it comes on for about 5 secs, resizes and has a orangy taint to the screen then goes black. The power light stays blue. I've replaced all six capacitors, the only difference I noticed from the guide to mine was there were four 680uf capacitors rather than all six being the same. I replaced them with 470uf. The capacitors I removed looked ok, no bulging or burnt looking.

Same here, 19", white screen. I did it the hard way though, first I assumed it was the mobo, so I got a new one with a processor, hard drive and memory. Then I hooked it up to see the same problem; white screen. So I ran out and bought a new monitor, but not a proview.
$600 later the problem is fixed.
Now I will fix the proview and give it to the girlfriend.
Sometimes I hate the way I do things.

Mine just stared doing this too. If back of your pc is close by I just unplug and replug the monitor back in to the video card port. Seems to fix it for now.

They should replace this monitor. KNOW one should have to do this. I am having the same problem and it should be recalled and I would not recommend this product to anyone or purchase this brand again.
Sad when it is only 5 mo's old.

Same problem - After dealing with the white screen issue for a few months my Proview PL926Wbi finally stopped turning on altogether. I went and replaced the capacitors (they were swollen and obviuosly bad) however, no luck. I'd imagine if the monitor would turn they might fix the white screen issue, but as of right now, the light doesn't even come on when I try to power it on. Any ideas?

Thank you so much for this information, it helped me solve my problem. When the monitor came out of sleep, it would only show a white screen with vertical scrolling lines. I took the monitor apart, and sure enough 4 of the 6 capacitors had blown. I replaced them with the ones from Radio Shack, and everything is working well.
A couple things I did differently which may help someone else.
1. I numbered each back light cable with a sharpie, and then numbered the corresponding connector on top of the "electrical cage" plate.
2. I put a small amount of hot glue around the area where the back light cables meet the 2 pin "white" male connector. This connection seemed very fragile and the hot glue gives it a little more support.
Tools I used:
1. Philips head screw driver
2. Soldering Iron
3. Solder Wick Rosin which absorbs solder
4. Standard solder
5. New pencil with full eraser
6. A small flat head screw driver
7. Electro static wrist strap
1. If you have never soldered before (I had not), practice on an old circuit board from a broken electronic. Also search the web for soldering tips.
You should practice both removing solder and applying new solder.
2. Remember to label all your screws so you don't forget where they go.
3. When removing the electronics cage plate, there are 3 gold screws which go in the corners, and 6 silver screws that go around the cage.
4. When disconnecting the back light cables, it may be easier to use the small flat head screw driver to get some leverage against the electrical cage covering plate.
5. When reconnecting the power cable from the LCD to the electrical cage, I used the eraser on the pencil to push it down on the ends without damaging it.
6. Make sure all your cables are well seated before you close up the monitor or you will have issues and have to take the whole thing apart again.
7. MOST IMPORTANT, take your time... Take it slow and be gentle with all the cables.
8. If you are worried about possible damaging the circuit boards with static electricity, make sure to use an anti static wrist strap.
Once again, thanks to all who did this before me for the great info!

Delphiuser and Guest (Oct.26, 2007),
Thank you for the fix. Someone gave me a PL926Wbi LCD yesterday since it was broken and didn't turn on. The blue power LED just blinks when you plug it in, and the screen remained black. I looked up possible common problems of this model and found this page.
Got the capacitors today and repaired the power supply board, and the screen is now working PERFECTLY. I had to also replace the 25V 220uF capacitor next the the group of 25V 470uF ones, since that one was also bulging/swollen.
The manufacture date on my LCD is Febuary 2006, and the person who gave it to me had it sitting around for a while after it stopped working. Seems like these screens are made to last exactly one year and no more, especially since the problem with crappy capacitors has been known for at least two years now.

I have the same problem with my 17 proview, I dont reboot the comp, try turning the moniter on and off a few times. Looks like i'll be heading to radio shack or best buy.

THANKS so much to Delphiuser ! Replacing the 6 caps has worked on my Proview LCD. How nice to have it fire-up like before. No more whitescreen-warmup nonsense.
Follow his instructions closely. Only thing I would add in is:
step 2 - your flexing out only the center section over the button area at bottom of screen(buttons stay on bezel). The edges don't release until the whole bezel slides up a bit.
step 4 - your removing the wires from the metal box - leave wires connected to LCD. (like he said).
And just to save you time - you need the radial lead caps, not the axial lead. Both wire from one end. Radio shack sells both.
Part number 272-1030, were in stock at local store.
Thanks Again Delphiuser - you saved me buying another monitor.

Ahh too bad, just ran into the same white scr problem with mine. It too is taking longer and longer to "warm up" . Can't afford a new one now so the Cap replace will happen if it does quit warming up. Up until now (about 2.5 years) it's been my favorite monitor ever. After the widescreen, I can never go back. Wonder if Delphiuser's monitor is still working after the "fix". Oh - no need to do a full reboot if the monitor is warmed up. I just do a <alt><F4> in the blind and then hit enter. On freshly booted XP system that should cause it to enter "standby" mode and in a few seconds appear to shutdown - screen goes black/blank. Then press any key (shift) and it will wake up much faster that reboot. If it's ready(warmed up) your gold.

Same problem - you have to reboot the pc though. 5 or 6 times maybe will work - maybe 10 times.. finally when the pc is off and just as you start the pc - you see the 'no-signal' box on the monitor and it will come on.. then its fine. sounds like a common problem - monitor is about 1 year old. anyone?
Posted on Sep 26, 2007
Just hope it keeps coming on. Mine did the same thing and I would let it "warm up" until it decided one day to not "warm up" any more. My suggestion is to have another monitor solution ready so when this one bites the dust, and it will, you won't be sitting without a monitor. Fortunatly I had an old CRT laying around (bulky but reliable) and got me back up and going. By the way, I wouldn't recommend another monitor of this brand, it was my first and it WILL BE my last.

I have the same problem with mine, can't fix it, but I know if you let it stay on while you wait until it warms up, then turn it off and back on it is fine.
