I have a Dell E173FPC monitor which I think I can probebly fix (by
replacing the backlight) if I could only figure out how to get the
back off!

Can anybody let me into the secret 9and if you have replaced the
backlight on this monitor, give me some tips on that too.

Thanks

Once you remove all the screws, most cases are held together by various
molded 'latches' on the plastic case parts that lock together with other
molded spots on the other part of the case.

Running a thin piece of tough plastic, such as a guitar pick, around the
seam will usually release the 'latches'.

I sharpen the handle of a 'disposable' plastic spoon or fork or use the
blade of a plastic knife to release the 'latches'. Cheap and some of the
plastic disposable utensils are very tough.

Here is a link to a site with the disassembly instructions and pictures
for the E172 which is simular to your E173.

It looks like there are 4 lamps and most likely you have a bad power /
inverter board not lamps.

I hope this is of some help to you.

Thanks for the advice Gnack.

I also got anothe rlink to a repair info site for a similar monitor at

http://syscon.wordpress.com/2007/07/...klight-repair/

This from Kelvin at Micro-Lite (www.micro-lite.biz)

He sells backlights in the UK and gave me some good advice (ie, he
thinks it probably isn't the backlight, and I can probably get the
parts cheaper on ebay than from him!)

I have orderered some replacement transistors from a guy on ebay and
will try and source some replacement caps also.

The trick for opening the monitor case was to use a flat blade
screwdriver and starting at the bottom seam twist while pushing in
quite hard. Then do the sides, then you cap just open the top without
the use of the screwdriver.

I will give an update to let you know if I get it working.

Thaks again folks!

Oh dear. The article you referenced is suggesting that you replace the
original 2SC5707 lo-sat switching transistors with MJE3055 audio
frequency transistors. That's a very bad idea.

Here in Australia you can get the originals for around a few dollars
each. Be sure to replace the electrolytic capacitors, and reflow the
solder at each of the coils and transformers.

Here is the datasheet for the transistor:

BTW, I've repaired a similar fault in a Dell (= Benq) LCD monitor,
model E172FPb.
