Help with PG vl2018w monitor

David, Did you find out which are the two 1000uF capacitors? I made the same
error and removed all five capacitors. I would be grateful for any help that you can give.

Yes.

There is a group of three transistors by the two power transistors on the bottom right of the card with the components facing you.

The two 1000uF caps are on the two that are connected to the two power transistors, with a 470uF cap in between them.

The fix worked perfectly. Only problem I had was having to switch to a vga cable because of dots... once I switched the red dots disappeared...

Amazing $7 worth of caps from radio shack saved, what about $200 monitor new?

Good luck!

    Sorry, the post should say "group of three CAPACITORS by the two power transistors"

Cannot find driver for VL2018W Monitor was working but then went blank Is it a goner or might the right driver help


Driver will not cause the screen to go black, look for bad caps inside, it is very common problem.

Does not start when cold


you probaly have bad capacitors. they store electricity. you can open the back removing screws. look at the capacitors to see if any of the tops are crowned or split. that is the most common cause.

My princeton VL2018W will flash the screen when first powered on but goes blank after. With repeated unpluging, the display used to stay, but no luck.


The power board probably needs an overhaul. Capacitors are probably the cause. It would have to be opened up to check that.
I repair many monitors through ebay and it is common on a lot of monitors.
If you take it apart and send me a picture to bammbamm@ptd.net, I may be able to see the problem.

Vl2018W princeton monitor


Hello,

If the caps you took out are rated at 50v it is best to use that rating, lower value caps can short out and cause additional problems. Also a white screen means 1 of 2 things, either the power supply is still not putting out the right voltage or yo have a small fuse blown on the lcd panel. The most likely cause is the power supply is still not right. If you can take a few pictures of your power supply board and send them to me at tech@ccl-la.com I will see if I can cross reference the board with something and try to help you out.

HP VS19e Monitor - no power


There are three (3) capacitors that go bad on the power supply board. MAKE magazine's Instructable site has a good guide on replacing them. I have a june 07 and july 07 date monitors. they were different inside!! identical outside, however. The bulged,'bad' components were 1000uf 10v cap's, I put in radio shack 272-1032 1000uf 35wvdc. My monitors? BOTH were bought for $35 on craigslist, $10.35 in parts. ???BusinFLA -at- hotma*l dot com.....worked for me!

Can changing 3 capacitors on motherboard solve my problem?


We had a power surge and my VL2018W LCD monitor stopped working... blank screen and flashing blue light.

I carefully opened up the back and found the power board (the one the AC plug goes into). There were about 5 electrolytic capacitors that were bulging (but not ruptured). There were 3 with the values listed by the original poster (470uF @ 25V) and 2 with 1000uF @ 10V.

I scrounged a couple of 2200uF@10V caps for the last two and bought 3 470uF @ 35V caps from Radio Shack (P/N 272-1030).

Luckily, the monitor came right back up and seems to be OK. It was out of warranty, so there wasn't a big risk.

Just increasing the working voltage won't do that much for you. If any caps are bad, just replacing them with the same value is good enough, but a higher working voltage won't hurt (usually means a bigger cap).

Good luck.

About the VL2018W (BLACK) Monitor soultion you posted


You need to replace 6 capacitors on the power supply board. Princeton uses CapXon brand capacitors which last about 1 to 2 years before going bad. CapXon are extremely poor quality capacitors, saving Princeton 10 to 20 cents per monitor.
This is the list of capacitors you need to replace. If they aren't bad now, they will be.
qty 2: 1000uF, 10V (DigiKey 565-1646-ND)
qty 3: 470uF, 25V (DigiKey 565-1677-ND)
qty 1: 470uF, 10V (DigiKey 565-1643-ND)

You can get United Chemi-Con replacements at DigiKey. The DigiKey stock number is listed on the above list. Since DigiKey didn't have stock on the 470uF, 10V at the time I ordered, I substituted a 680uF, 10V (DigiKey 565-1644-ND) which is a larger diameter, but will fit in the area provided.

Comes on for about five seconds and then goes dark


MAKE SURE THE CONNECTION BETWEEN YOUR MONITOR AND YOUR COMPUTER IS PLUGGED IN TIGHTLY AND CORRECTLY, YOU MIGHT NEED A NEW POWER CABLE OR A NEW CABLE THAT CONNECTS FROM YOUR MONITOR TO YOUR COMPUTER, TRY CONNECTING YOUR MONITOR ON ITS OWN PLUG, OR IN ANOTHER SOCKET AROUND THE HOUSE IT MIGHT NOT BE GETTING ENOGH POWER, IF IT IS NOT LCD MONITOR (NOT FLAT) THEN YOUR COMPUTERS BULB MIGHT CIRCUT WRONG
