How do you know if an lcd is dieing?

nite_monkey:
that sucks. I guess I will end up haveing to use my tv until I can get a new monitor... oh well

Shades:
Although the price of a new monitor is low, it can be (sometimes) easy enough to repair...I should say exchange parts. Recently I did that with two broken LG's of the same type/model. One had a lot of dead pixels (more like a black hole) and another that would not turn on anymore.

On a lost Sunday I took both apart, exchanged parts and now there is one functioning monitor again. That was actually (relatively) easy, since the LCD panel itself and the electronics were two separate parts that were connected with a flat cable that slides into a click-on connector and an earth/mass cable. It was harder to open the LCD panel (without damaging it) than exchanging the parts.

Of course, your mileage may vary.

Crush:
The LCD of my old laptop loses each week a few lines that show up with random colors. It only serves as a DVD-player and HD-Recorder after that. A new LCD would cost about 400$ - for this money I could buy a new one for the same task.
My old tube monitor also turned black sometimes. I tested the electronics (be careful if you also do so!) and found a cold capillary joint that only had to be renewed. The pin had no perfect contact and was able to move around.

f0dder:
My 17" Acer died some months ago, it would go black but the LED would still be green (ON mode, as opposed to orange STANDBY). Changing resolution or un+replugging the monitor would cause it to work for ~10 seconds, after which it would blank out again.

Any ideas what could be wrong? Ended up buying a new monitor, but if it's something that could be fixed cheaply, having a spare monitor would be nice :)

OldElmerFudd:
Don't mean to hijack this thread, but it covers one of the thoughts I've had for a while. I use CRT monitors because of the graphic work I do. Anybody using higher-end LCD monitors? I could use some recommendations about longevity and accuracy.

The kind of comments by mouser and nite_monkey reflect these concerns. At least it gives me some idea what to expect when a monitor starts to fail.
