Question about Dell P1110 21" CRT Monitor
I am trying to fix my dell P1110's brightness problem using WINDAS software and a RS232<>TTL cable to lower the G2 value, but whenever I connect the cable to the four pin header on the back of the monitor the monitor screen goes blank and the green light turns amber. It's very frustrating, and I am hoping someone out there knows why this happens or how I can get around it.
Use original software for the device. Check to see if monitor is compatible with the motherboard

you need to either buy a new inverter board, or if you are competant with soldering onto boards, you need to replace the c5707 transisters at points q740, q739, q760 and q759 on the larger board. best place really for the replacement c5707s is ebay

Cause of power going
off: There is a bad 1000uF, 16V cap
on the power supply board.
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.

Hello,
You have a monitor with a common problem. After a few years some LCD monitorswill
blow a power supply. The problem is caused by parts calledcapacitors
overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou
can take the back cover off your monitor and look for the bad
parts,replace any that look like the pictues and your monitor should
workfine. The capacitors do need to be installed with the correct + and
-connections, note the stripe on the old one and insert the new one
thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.
