LG 42LE5400 Image Problem

[texhost]

We have a LG 42LE5400 that has a two darker sections (one six inch vertical and the other one is about four inches) of the screen starting in the middle and there is a second one on the far right of the screen. They darker sections still contain the images fed to the TV, but they are not a bright or in a lower quality of image. The problem started after the tv was accidentally splashed by a garden hose. It was not a direct hit. Rather is was slightly sprayed by the hose. I think the problem is either the a/v board or the actual screen/panel. Is there a quick way to diagnose between the two? Also when you input screen is not active (e.g., whatever is being fed the hdmi, etc) and the onscreen menus are on the screen, you can still see the darker sections of the screen.

Any ideas?

Thanks in advance

The tab bonding may have been damaged by corrosion, see example here:

Did you take the TV apart yet?

yes. The tv is apart. I did notice and corrosion or any electrical components that appeared burned or shorted out.

The simplest/fastest way is to try a similar screen panel and see..I know you may not have one

The average individual doesn't, I don't keep spares...

Re: LG 42LE5400 Image Problem

I recovered an LCD TV that had been taken to the garbage tip because of the infamous power supply capacitor issue. We'd had some rain during the week and the panel had been face up to the rain. On intial startup it was apparent that it had water ingress into the panel laminations. I place it in direct summmer sunlight for about 6 hours and when I fired it up I found that a significant amount of water shadowing had disappeared. I repeated the process for about a week and most of the water appeared to evaporate out. It's not perfect but most people don't notice the imperfection unless it's pointed out to them. Maybe worth trying because your description certainly sounds like water ingress into the panel.
