How dead is my monitor?

Turned on my monitor the other day and was greeted with the below sight!

Have checked the capacitors and there are no noticeably blown ones, have also checked and reconnected all cables inside.

Anyone know if this is salvageable at all? Or has the LCD gone kaput? :eek:

That sure looks like real curve ball...
There shouldn't be any way for capacitors to cause anything like that in LCD.

Maybe panel's control electronics could be reason...
Problem in cable between it and LCD panel itself could cause some vertical patterns...

Is that TN-monitor?
TN LCD crystal without control signal in "relaxed" state shows white.
 
I use to work with monitors / stripping them down from laptops etc for individual re-sale.
I'd say it's pretty knackered. There are various companies that sell just the panel. Can you take the surround off without damaging it?

It's a TFT if that makes any difference. Have had a quick look at the boards and can't see anything obvious... but this isn't really my forté.

Yeah, I was thinking it was probably done for, but thought it was worth checking anyway.

Had it for 5+ years, so it's had a good life!

TFT is just certain manufacturing technology of panel's pixel control circuitry, not LCD type.

This looks similar in style but instead of white is darker area:

Problem in control wires of LCD matrix cause this kind vertical banding/stripes:

Did you take any images?
 
Dell are one of the most unreliable brands of monitors on the market - my own managed to fail 3 time in 6 years so there's loads of info on pulling them apart.

This fault looks almost identical to one the Dells suffer because of the inferior components they use, in this case the connectors which are not plated and corrode causing bad connections. On The Dell there are two one for each side of the screen from the scalar board, you need to buy a decent switch cleaner and then disconnect and connect a few times to scrub the corrosion away, alas though it's not a permanent fix, and the problem will return again in time.

There's a you tube video showing the problem here, which clearly separates the display in two halves.

Thanks for those, will have a look at what people are saying they've done.

Would have made sense to do so while I was in there, can take some if you'd like to have a look though :D

Cheers, will have a try at this!

Have been googling like crazy since it happened, but its so difficult to pin down what it is to find relevant answers on there!
 
The main issues with Dell are blown caps - you should take a google at what these look like so you can recognise them.
Corroded connectors - it won't hurt to clean each one you come across with switch cleaner.
Dry joints - again google what these look like, they are a fairly easy fix if you have a soldering iron.
