TFT LCD - a step backward ?

In the past, when the big-fat monitors were still been used, if
there's any problem with them, I can open them up and find and fix the
problem.

Nowadays, where the TFT LCD bunch is taking over, when a monitor fail,
it just dies. Can't be repaired, nada, zilch.

To me, the TFT LCD represents a step backwards. I have on my hand 5
TFT LCD monitors that lie belly up, and I just can't fix them ! All of
them have the same problem - the back-lighting fails, but since
everything is compressed into a compact module, there's no way to fix
it !

Darn ! !

That's what I expected, but I'm happy to report than I've had more
success fixing LCD monitors than I ever did with CRT monitors. The
most common problems are simple things like bad caps and back light
problems. The inverters can often be repaired (about half of them
just have a blown fuse). I've never had to replace a CCF tube in a
desk top monitor, but at least it's possible unlike when a CRT gets
dim. Most LCD monitors are also much easier to take apart and work on
than CRT monitors. There's no more rebuilding the deflection circuit
only to have everything blow up again because the unobtainable flyback
is bad. The best part is that LCDs are light weight and easy to
handle compared to CRTs.
