can someone with the knowledge (either a schematic or the board itself) tell me about the ceramic capacitor c821, i stupidly damaged it when removing the caulking compund to work on the three capacitors around it and the plates inside are exposed and i cant tell what the printing on the capactitor says to purchase a proper replacement. (my model is a vs19d) judging by the comments here they obviously have the same guts.

For me, it turned out to be bad capacitors.
After disassembling the unit, I could see that three of the capacitors looked different. The tops were bulging. See http://en.wikipedia.org/wiki/Capacitor_plague
I replaced those three and all was well.
- The curved plastic top piece of the pedestal stand pops to allow access to the 3rd pedestal screw.
- The entire pedestal assembly then slides toward the bottom.
- Use a small flathead screwdriver to pop off the front cover. (but not tiny, that was my initial problem)
- Write the colours of the four wire pairs in pencil on the metal screen so you remember which goes where.
- Remove the small metal cover from the larger metal cover to access the ribbon cable connector.
- To disconnect the ribbon cable from the circuit board, carefully pry up the black strip on the connector.
- The power button cover, bottom of the U faces the back of the case.
- The other button cover piece has tabs that fit into the small switch circuit board
Hope this helps!

I have an HP vs17e bought in 2006. This happened a few weeks ago - blue light blinking, totally blank screen. Then fixed itself. Now is doing it again. Flashlight test revealed nothing.
Could this have something to do with heavy usage/having the monitor on all the time? Between my daughter and I the computer and monitor are busy from 6 a.m. to 12 midnight, 7 days a week.
Not skilled enough to replace capacitors, will probably have to buy a new one. Any suggestions for a high use monitor? Prefer to stay with HP products.

I am having an isssue with my hp vs19e with a blinking blue power light at startup after several minutes it will go through several screens with vertical lines and then from the top down sections of black appear after this it powers up fine and will stay on just fine but it takes about 5 minutes. other monitors work fine with this machine so it is in the monitor. Are my capacitors going bad or is this a sign of some other problem?

I have a vs19e monitor that had the blinking power/blue light ... I used the instructions in the linked website and I'm using that very same monitor to send this message.
Thanks so much for the info!!!

Thanks for this great info.
I found two of the three 1000uF capacitors on my HP vs19e had failed exactly as described.
Two hours after reading this info, I had three new caps from Maplin (UK) and replaced all three originals, just in case the other one was on the way out.
Now my monitor is good as new. £120 saved.

HP t3569 / Hp vs19e monitor
Just got back from a few days away and, having turned everything back on, I noticed the blue light on the side of the monitor slowly flashing and a blank screen....after about 30mins it came alive and all seemed ok. Next morning however on powering up the blue light flashed contnuously and the screen stayed blank.
Swapped monitor to another system, same result blinking light, blank screen. Connected up old monitor and all working fine!!
Loads of similar cases here do you think HP might send out a fixit or some capacitors or something....!?!
Great info on this topic. Will give the repair a go....now where did I put the chainsaw and acetylene torch?
