Repairing a vs19e

Step 8 The problem children.

Okay, so now you have the power supply out of the monitor itself. You have made it this far. See that wasn't so bad, was it? The three power capacitors in the bottom left corner were the problem for both of the two screens that I have repaired already. If you look at the top of the capacitors, chances are some are bulging and possibly leaking. Just because the bad capacitors in my monitors where these three, doesn't mean that yours will be the same ones. Look at all of the capacitors on the board. They should be good, but your already here, right?

Replace these with the capacitors I talked about in the intro from "the Shack" (it's all I have here sorry... I know they are id10ts) or ones that you picked up somewhere else. Make sure you pay attention to the stripe (the negative side). Installing them backwards will cause them to pop and you will have to do this all over again, if your lucky.

Once you have soldered these three (and possibly others), reassemble! Snap everything back together, screw it all down, etc.

Now plug it in and see if it comes on. It should...

actually worked! soldering was not easy.

i blew about 4 capacitors and 6 resistors... theres white gunk all over the board now. don't think its coming back to life, thanks though, im salvaging it for the LCD screen which is still good condition.

Always been intimidated by the inner workings of all the high-tech stuff but I read over you instructions a couple of times, bought the parts (only a few bucks), and gave it a try. It was as easy and just as you described it... until I got to the soldering of the capacitors part. Stepped away for a few minutes, found a video that showed how to solder capacitors to a circuit board and my monitor was back together and working great in no time. I was so close to just tossing the monitor until I found your tutorial. If I can do it I'm sure just about anyone could. Thanks.

Hey Thanks! I got to work this morning - black screen. found this link and quickly repaired an HP vs17e monitor. It's a little different than the 19, but close enough. Screen works beautifully now. Had the blinking blue power light and black screen prior to repair.

Hey I just found this tutorial. I have had two monitors go bad and they have been in storage for over a year. I opened up one and saw that 3 of the capacitors were bulging at the top and then there were a couple things that were leaking I guess? It was like hardened white foam near them. On a couple of things that look like larger capacitors and then on a couple of these little light blue things. I know nothing about the insides of electronics, so do I need to replace those too or just the capacitors or should I just junk it and try the other one? I was hoping it wouldn't take too much money or time to get it fixed. Thanks.

The hardened white foam is most likely just an electronics glue put on the circuit board to hold parts in place (or some such thing). Pretty much every circuit board I look at has that stuff on it, in one form or another. It's easy to spot the bad caps, though. Just look for the bulge... (And as a side note, the caps I replace in A/C systems every day bulge in exactly the same way - even though these caps are usually about the size of a soda can.)

My circuit board and the screws were in different spots. Just took my time and figured it out. Replace the 3 capacitors (now 35 volts), they still fit. It works fine now. Thank you!!!!

I'm not sure why, but my monitor has one circuit board containing power supply and vidio board all in one. The capacitors were easy to locate though. Rounded on top as discribed. When tested they only showed about 200 micro farrids. I replaced them with 16v instead of 10v hoping it will prevent future failures with a heavier duty capacitor.

Thanks for the excellent tutorial. I replaced the three capacitors and it now works fine. I was really surprised at how easy this was to do.

it worked great !!! it was also a really fun father/son activity

[mmb2006]

great instructions, easy taking apart found the problem. 10 capacitors leaked over the board. decided just to junk it . thanks for nice tutorial.

[computergig1]

worked great!! the part number for the electrolytic capacitors at radio shack turned out to be #272-1032, thanks for a great tutorial!!

[gr8whtd0pe]

yeah I see that I linked the wrong one, oops. Lol even though I had the package in front of me I still did it wrong. Oh well. Fixed on the first page, thanks.
