Re: Samsung UE40C6620 LED LCD Discolouration

Thanks for the pointer, but no luck.

What puzzles me about this (as opposed to other cases I've seen, like the one you linked) is that it is affects exactly a quarter of the display; the other three quarters are perfect.

Could this be symptomatic of a T-Con issue, or do you think the panel toast?

Re: Samsung UE40C6620 LED LCD Discolouration

Any thoughts on this?

Have done a fair bit of searching and can't find any comparable cases on this forum or elsewhere.

Hi all,

Having an issue with a Samsung UE40C6620. Unit was purchased new in 2010. It's a 40" LED LCD model, UK spec.

A few months ago an intermittent fault appeared. The defect is hard to describe, but is shown in the attached images. When the fault appears, a quarter of the screen is discoloured with waves of blue pixels.

The issue affects all inputs. It is intermittent, so for extended periods over the last few months it has gone away and the image has been perfect.

It appears to be an issue with the blue channel in that section...

Re: Dell 2407WFPb Monitor - Bad Cap

Minor update as promised.

Swapped out the 450V cap and the 4A/250V fuse, pieced the unit together and tried powering up. Fairly certain I heard a popping noise of some sort. Otherwise, no signs of life. Opened it up again, swapped the fuse out and tried again. Definitely no noise that time, and again no sign of life.

No visible damage to any components as far as I can ascertain. Probably going to shelve this until I have more time to look at it, and just get a new monitor in the meantime...

Re: Dell 2407WFPb Monitor - Bad Cap

Thanks everyone for the advice.

I've ordered the replacement 450V cap and a bunch of new 4A/250V fuses. I'll attempt the repair job on Wednesday and will report back with results. Given that my unit seems to have significantly less initial damage (at least based on a visual inspection) than the others I've seen posted in this thread, I'm intrigued to see how it will turn out.

In any case, if worst comes to worst, at least I'll get a fireworks display out of it!

Re: Dell 2407WFPb Monitor - Bad Cap

Hi all,

First of all, thanks for all the messages everyone has posted in this thread so far. My 2407WFP went pop the other day, and I came across this forum looking for information on how to fix it. The wealth of information in this thread has been extremely useful and encouraging.

Anyway, I've opened my monitor up to have a look around, and the only sign of damage I can find is the 450V capacitor. All the other capacitors, resistors, etc. seem fine. Apologies for the abysmal picture quality, but you can see damage...

Hi all, I'm just here because my Dell 2407WFP has gone pop and I'd like some advice on how to fix it
