The top panel is on plastic clampers. Take a flat thin object and pop it along the perimeter. All the screws are inside on the perimeter of the LCD panel underneath the plastic panel.

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..

My HP vs19e flat panel monitor began taking longer and longer to come on and now it's hours. I'm afraid that one day it's not coming on at all. I have been leaving it on to keep from having to wait but...


Haven't run into this particular problem, but many have been able to fix their monitors that won't come on with my tutorial. See the link below:

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.

those capacitors are polarized they have a neg and a pos side were they seated correctly? could also be transistors going bad but my bet is some cap was in backwards.

Will not turn on


Hi,
You can try the following steps:
1. Disconnect all the cables from the monitor
2. Wait for 5 minutes and press the power button in the front once ( donnot connect the cables at this step)
3. Reconnect the power cable only to the monitor
4. Power on the monitor and check if you see a self test running on the screen

If the selftest feature is not running the monitor has gone bad. All dell monitor if purchased on a seprate order ,hold a 3 yr replacement warranty. If you have got the same with your dell computer, call Dell to check if its under warranty.


Thanks

time for a replacement with the amount of data supllied, also see if the light indicator button comes on, if there is power, then check the video plug and card, do another video card and see if that corrects the problem.

Solution: Replace cap. Radio Shack sells a 1000uF, 35V cap for $2. This will work.

Why did the cap go bad? The cap is too close to a heat sink and over heated.

What does this cap do? This cap sends a signal to an IC which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is applied to the IC and it sends a signal to shut the monitor off.

Opening the Monitor: These monitors are difficult to open.

The two plastic pieces snap together and must be pried apart with a flat screw driver.

After removing the stand, you need to insert a flat screw driver at the bottom of the screen where two slots are located. Then work the screw driver around until the two plastic pieces are separated.

Remove the cover plate and unscrew the push button circuit board.

Unplug the monitor cords from the driver board and remove the screen.

Unscrew the mounting screws from the power supply board and remove.

You will need to pinch the plastic support in the middle of the board to remove.

Cap Replacement:

Cap is located near a copper heat sink and the value will be on the side of the cap. It will be bulged up on the top. You will see burn marks on the board surrounding the cap. Unsolder the cap.

Install the new cap and solder. Make sure you connect + of the cap to + marked on the board.

Be careful not to solder across joints.

Keep leads long so you can bend the cap as far away from the heat sink as possible.

Reassemble monitor and turn on.

This should solve the problem.
