    I also have an HP VS19E monitor; 16 months old, no power. I have to seriously reconsider ever purchasing another HP product again.

    HP vs19d Monitor, working fine one day, next day no power. Tried new power cord, still blank screen. Took to local tech. He plugged in my power cord and the monitor worked fine. He said sometimes you have to push cord in very hard to make connection. Back home I plugged it in again and it worked about 6 hrs. Next day, blank screen. Removed cord, pushed in hard, wiggled it, pulled it out, cleaned contacts, reconnected. Still 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!

Hp monitor wont turn on.


Hello,

First, remove the power cord from the wall, insert it into another outlet. Also, change the power cord, in case it is bad. Sometimes a bad power cord may not pass current into the monitor. But if problem persist, then it means the monitor is having a power problem.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The monitor is receiving current but cannot circulate or transfer the current to other necessary part of the monitor because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your monitor not to power on.

All these can be checked on the power supply board.

But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about monitor repairers, take the monitor to the nearest repairman to fix the fault for you. Also, note that monitor stores a lot of current, so wait a while before opening the monitor back cover.

I hope this helps.

Regards.

Hp vs19e lcd sreeen stoped working power light button does not come on, the monitor is around 4 years old is it worth fixing or time for new one?


If you have it repaired by the shop then it will not be worth it, if you want to DIY repair then you need to buy proper tools.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed HP monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My HP vs19e monitor takes almost 5 minutes to "wake up". Works fine once running. It never took this long before. Any ideas?


most common problem is bad electrolytic capacitors if unit is a few years old. Take it apart and replace any swollen, ie bulging top of the aluminium can... but may be 'off-value' if not swollen. Any electronics from China will fail within 3 years due to bad electrolytic caps..

I want to replace the power switch board on my hp vs19e monitor.


About your only hope for getting a replacement switch is to buy a "Parts Only" monitor off of EBay and carefully remove the switch. This one is tricky it's attached to the front bezel as you've likely found out. When you disassemble the monitor, lay it face down and remove the bac plastic then remove the 4 screws holding the button board on then take the rest apart. That's the safest way.

I replaced the 3 capacitors now there's just bright white screen


Open your monitor back up and look for unplugged connectors, especially the one to the back of the LCD. I had this same problem with a HP F1703. The owner whacked it so hard when the backlight stopped that they dislodged the connector.
