Re: Dell P2412h LED monitor shows pink tint in white screens
I will try that with the cable pulled as soon as I get a chance.

Re: Dell P2412h LED monitor shows pink tint in white screens
Thanks, Ifixstuff9, I was told by a tv repair guy that it's probably the T-Con board along the bottom of the panel, and not repairable (I tried to separate one once and of course just split the glass open as well) and not worth fooling with for a $45 monitor used. But it may be the LED as well; I had an old Sony clock radio where the LED display got dimmer and dimmer over time until you could only see it a bit at night so they can just wear out. Either way, it seems to be the panel that's the problem. I'll keep watching...Leave a comment:

Re: Dell P2412h LED monitor shows pink tint in white screens
Well, I wasn't entirely sure, so I just hooked everything up again. I also have another Dell E series 24" so I put both in diag mode and went through the colors side by side; definitely a pink cast to the white. Comparing the two shows the moving box also pinkish, and there is a cast to the OSD menu too, although not quite as obvious.
So, no one thinks it's the power board, that it's either the signal board or a bad cable. I used Deoxit on all the cable connectors, too. I keep looking for another of the...Leave a comment:

Re: Dell P2412h LED monitor shows pink tint in white screens
Ok, let me restate in more detail for those who assume I am not smart enough; I have done all the obvious things, changed cables, both inputs, tried 3 PC's with multiple cables, ran the diags on it, fooled with the color settings, wiggled the cables as well. I just need someone who has faced this and discovered where the issue is; the power board, the signal board, or the panel itself. Thank you.Leave a comment:

Re: Dell P2412h LED monitor shows pink tint in white screens
Again, I appreciate it, but I have, repeat, done all the obvious steps! I have been working on computers for almost 40 years. I just need an informed answer.Leave a comment:

Dell P2412h LED monitor shows pink tint in white screens
All the whites have a pink tint, tried all the obvious stuff, different cables, different pc's, etc. Took it apart, and the power board has cheap looking caps, but no bulging or any signs of going bad. Signal board has all small caps, all look ok, usually small ones not a problem. Tried deoxing all the connections.
I don't know enough to test, but I can solder great and have repaired a lot of monitors by recapping the power board (mostly) with good Panasonic caps and sometimes the signal board since I had it out.
I can go ahead and recap the power board, but don't... -
Re: Dell G2210t lines on screen distorted text is it a bad screen?
Sorry it's been so long since I've revisited this topic.
It sure looks like the bad T-con board as you have described.
However, pardon my ignorance, but I thought the t-con board was only in TV's? I have to pull this back out of the box in the garage and take apart again, but there were three boards in it, a main board, PS board, and a real small board labeled as the inverter board, seems to mostly be a couple transformers on it.
Which board is it? Or, is it the board...Leave a comment:

Dell G2210t lines on screen distorted text is it a bad screen?
Have this Dell G2210t that I can't figure out. Has a LED backlit screen.
It starts up with lots of vertical lines, and returns to that when coming back from sleep mode.
I changed almost all the caps for nice Panasonic FR's. Even though none looked bad, they were Suscons, so I changed all but the tiniest ones.
The power is good, and after a while, the screen brightens up, the vertical lines kind of go away, but there are fine horizontal lines that stay, sort of looking like corduroy pants. The text remains hard to read, like it isn't all there.

Re: HP W2207 What are the right caps?
Like the Samsungs, these come with either the highly adjustable stand, and also the small static one, I believe. Anyway I've seen it before. The actual stand is what has the pivot. I have no idea how the monitor knows it's pivoted, but it seems to.Leave a comment:

Re: HP W2207 What are the right caps?
Ok, I fixed my own issue. After realizing this monitor pivots, I then remembered I had to pivot the monitor slightly to access the VESA mount screws. Evidently, it was enough for the menu to come up sideways, even though the screen was oriented properly. When I put the stand back on, and turned it back to normal where it kind of clicks in, it fixed it!
I'm not sure I will replace those final two caps (they are the 1000 25v Suscons) if it will last as long as the one RetiredCaps has since he only replaced the bad caps as an experiment....Leave a comment:

Re: HP W2207 What are the right caps?
Ok, all, I recapped alll but the two 1000-25's I didn't have, but it came right up and worked. At first it didn't light up but the image was there, then I realized I hadn't plugged the bulbs back in!
Now I have a really unusual problem I've never seen. The OSD menu will pop up at power up on top, then immediately pop over left so it is horizontal. It all works, but sideways. Tried monitor reset power off, through menu, rotated the display through Intel's driver app, nothing puts it right side up.
Has anyone else ever...Leave a comment:

Hey, thanks for the photo, retiredcaps, it looks exactly the same, down to the same two bulging caps as mine.Leave a comment:

Re: HP W2207 What are the right caps?
Thanks again. Selldoor, that all makes perfect sense to me now.
I will go ahead and use 105's and just match what's there. Now I just need to get some 1000 caps; I hate having most but not all of what I need and have to pay for a short order, and I don't have those.
I did read most of those threads, probably missed a good list of caps, but in light of the comments, I'm going to do it as above, just match what's there and see if that works.
It's really great to get the comments from all who have experience...Leave a comment:

Re: HP W2207 What are the right caps?
I really appreciate the suggestions, but I still want to find an answer to my main question, which is what the factory farrads of the right caps are. Again, I will replace with good low esr caps and use 105's if that's the consensus, but I really don't want to have to go back into this monitor again and if I make sure then I won't have to (at least for caps).
I like to be exact as I can, even though I know you can sometimes get away with a lot of fudging, I just want to make sure before I do it if I can. I would hate to give someone...Leave a comment:

Re: HP W2207 What are the right caps?
Thanks for all your help. What I am wondering about is if the 680 cap is the right one or not, when the cap kits listed an 820 I don't seem to have but it's the same board.Leave a comment:

HP W2207 What are the right caps?
Picked this up dead, opened it up and found some bulging caps. I always recap the whole thing to make sure, with low-ESR caps I get from Mouser.
When I started listing the caps, I found some 125° caps in with the normal 105's. I went to Ebay and looked at 3 different cap kits to see what they included. None were the same as my board, and none had temp ratings other than 105° for all the caps in the kit. Some kits listed less 680 caps then I have, one listed an 820 cap I don't have, so I am now confused as to what is proper for this board.
The power board is what... -
Re: Gateway FPD2275WH still no display need help troubleshooting
Hey, thanks, that's what I was hoping to hear.
I think I blew out my last $5 one. The 410 is unusual and I never needed that scaling before; I actually bought that one because it has a temperature probe I wanted at the time.
Question: are the Fluke listings in any particular order, meaning the first is the best and on down the line?
Being inexperienced at troubleshooting boards, yet having mastered replacing blown caps with good low-ESR's from Mouser, I want to make sure...Leave a comment:
