I SO regret buying this set now... At the time, it was a superb deal, with awesome picture compared to other sets. Now, it's pretty much shite...anyway, I'm stuck with it until I buy a new TV, so might as well try and figure out if I can fix it.

My Viewsonic N3751W has a "dark patch" along the middle left of the screen. Is this an easy do it yourself repair or should I just not bother? Below are some pics of the screen...

In the one of the boy, you will notice there is a dark blotch on the left near his face.

However, in the picture of the man, the spot is hardly visible.

For the Family Guy picture, there's a dim brown area left of his face.

Ideas of what this could be? Or should I basically just throw it in the trash and not even post it for sale...

Looks sort of like clayface that used to occur in the early days of LCD and Sharp had it briefly and was fixed via firmware but that's about 6 yrs ago.

I once bought a Viewsonic for my network thinking it was a good budget panel but they proved to be crap - the first one arrived and anytime you played a DVD on it you'd only get it in black and white no matter what you did.

So I returned it and the replacement arrived ten days later and it arrived with it's bezel broken off and apart from the TV and then I had to get yet another replacement from them and in total it took 6 weeks to get a Viewsonic that actually worked and there'll never be another on my network and never in my home that's for sure. I place them along with Magnavomit and hence the term Viewvomit and your Pic's are testimony of it.

Ha ha ha... Funny funny. Yes, bad purchase, but at the time no one knew that and it was good for 2007.

I'm hoping I can get $300 for it. Most regular TV users wouldn't notice it but afficionados like myself, do.

I don't know about no one noticing it, it is pretty extreme in the one pic.

I personally could never sell the set without pointing it out to the buyer.

My Toshiba seems to be developing this problem, but to a much lesser degree so far--the background has to be white or at least very light to notice it. At first I thought it was dirt behind the front glass but it looks a lot like your pictures.

I'm interested to see if anyone can tell us what it is.

Take a pic if you can and post it-- how old's the set?

Oh, and no-- I definitely wouldn't try to hide it. FULL DISCLOSURE!! to any buyer. Gonna sell AS-IS.

Personally, I'm confident the set will last me years to come without any further problems...but it's just time for a newer, bigger one.

It's about two years old.

I don't think it would show in a picture, although my wife noticed it, and she never notices anything!

it seems like bad panel... does the situation improve if you apply slight pressure (with your finger) to the affected area on the LCD panel?
