Hi,

I bought a 3007FPW on ebay and the seller packed it like it was a beachball, it suffered some cosmetic damage but plugging it in I was hoping it still worked ok.

But.... looking closer I think the lower left corner has suffered some damage to the backlight.

Although I have not owned one of these monitors before, I was aware of backlight uniformity issues with the 3007FPW, particularly on the earlier A00 units (which this is) but pretty much all the examples I have seen exibit a bright right hand side and a slightly duller left hand side, where as this unit appears to have that issue and also a large rectangle of almost no backlight.

Anyone owned one of these, opinions appreciated? :)

The 3rd image (worst looking one!) is how it looks when I have it set at a low brightness, which is basically how I would normally use it.







Thanks
 
My screen behaves exactly the same! not sure if it is A00 or A01 however.

You might find, as i do, that running full brightness for a while will bring the weak tube to life, you can then drop brightness slowly till you find the point before it gives up. Sadly, this wont be anything like minimum brightness, but the evenness is preferable.

note; mine is slowly worsening, so i suspect the tube in that corner is simply weaker than the others (shorter/longer/more stressed/hotter/colder/not well attached)

ill check it out properly when i have time, but let us know if you have any success
 
Thankyou very much for the reply. It is good to know that it can be affected by leaving the brightness at a higher level for a period of time, because that is exactly what I did last night (with an almost bright white background on full screen as well) and afterwards I turned the brightness down atleast half-way and I thought "oh, this isn't so bad".
I then powered it off and came back to it 3 hours later only to find that it was way too dark to be acceptable, and even at full brightness it was barely lit at all, and it is still that way tonight, but atleast I know I wasn't just going mad! :)

Have you had yours from new? Has it just developed this fault, or is it also possible it suffered some impact that has triggerred this?

Strange that it is the bottom left on yours as well hmmm :)

Thanks again!
 
I have had mine, second hand, a few years. The issue developed slowly, but i think it was triggered by a knock during moving home. the screen has definitely taken an impact to top right corner before as it has characteristic injured IPS sub-pixel noise there.

I might try and mod it for LED backlight at some point, or see if the error might be fixed. for now it works just about well enough.

There are disassembly videos on youtube and one chap who posted them says in forums that he has never seen a tube go bad, and very few inverters on these screen. he does say to check the tube plugs for bad contact or failed insulation, however.

*edit* West country too here! yay! Water.....
 
Yea, I am in the water plentiful south west, mainly South wales these days though.

After having a quick look at repair options and finding the parts a little hard to come by and expensive once imported from the US, I have given up on the monitor and it is going back Monday.
I paid £370inc for it and even if I had a £100 refund I wouldn't have the fantastic monitor I wanted. If I didn't have the option of a refund then I may have gone down the LED route too, but I decided that I may as well spend £500 on a newer perfect panel than end up spending near enough the same on what would be a DIY'd and still old panel.

Thankyou very much for your replies though, it was very helpful! :)
