Possible Samsung Acquisition

[LAS]

Hi Badcaps folks,

A local individual is selling a 22 inch Samsung with the following output as shown below. There is a blue box in the upper right hand corner.

Bad cable perhaps? Bad connection?

Available for the princely sum of $20.

Be careful... The model shown in the picture is a Dell, not a Samsung... I smell the old bait and switch.

[Jasgriff]

Yep I agree with mocking bird that definitely looks more like a Dell than a Samsung

Not sure if that can be a bad connection because it would be a full strip right down the screen. I might be wrong though.

[LAS]

My oversight...actually advertised as a Dell.

[smason]

I wouldn't pay $20 for it.
Looks like a tricky fault to locate.

Bad panel or bad logic board. I'd suspect the logic board (or tcon if it has that separate), because when the defect is in the tab bonds of the panel the defect will span the entire screen, either horizontally or vertically - the display is driven as rows x columns. You could get several thin colored lines that stay on, half the screen white, or similar things, but i've never seen a panel making a blue box like the pic shows.

I'd pass, unless you have a similar one with a broken screen. Would be an idea to check how much a logic board/tcon costs tho.

Thanks all for your input on this monitor for sale. At this point it looks like a challenge I don't think I wish to take on. Saturday I will investigate another candidate which looks a bit more straightforward.

osd setting on monitor maybe? seen a tv with that, an it was an id 10 t error! simple click changen osd settings got rid of it!

[LAS]

Hmmm. Maybe - I see the monitor does have an osd setting on another of the images in the ad.

I've got the feeling that TJ gets a gold star for this one.

The monitor is across town, so I had a local buddy of mine swing by and buy it for me. The actual model number is a 2005FPW, and since it was advertised as a 22", I had him squeeze the owner for a few bucks. Total was $15.

Attached is a second photo from the Craigslist ad. If you look closely, the PIP source is 4Composite which I believe to be unplugged. It should say unassigned or something to that effect. I'm betting on an easy adjustment for a fix.

[t.j.]

good score ! hope that all it was!
peace

Yeah, it has PIP/POP - and it is trying to show the second source in the small window.

Update on the Dell 2005FPW...there were a couple of issues going on. First was the aforementioned blue box where the PIP should be, and this was rectified in the first few minutes.

The second issue was the often-reported issue in other threads where there is a rolling, not unlike a TV's vertical hold. It went away after a few minutes, which made me think it was a caps problem.

I went into my bag of tricks and found replacement caps for most everything on the power card, with the exception of the 1uf 50v. For that, I used an FC 2.2uf 50v. If anyone thinks that was a bad move, please advise.

Well, the problem was mitigated somewhat but didn't go away completely. So upon further research, the culprit was previously identified with some bad caps on the logic card. So I did some esr testing, and saw that the 470uf caps were all registering about .50, while new FC caps were more like .03. So I changed the three of them, and I am pleased to report that the issue has not gone away completely.

I will test the usb functions most likely tomorrow but I have high hopes for that.

Next up: a flickering Samsung 22" being advertised down the street. He wants a lot but my pitch is getting better.

LAS.

I think you mean "now". Otherwise, I don't think you would be pleased!

Good job. Looks like the ESR tester is starting to pay for itself.

[LAS]

I stand corrected!! And I do like the esr meter. The absolute numbers are not so meaningful to me, but the values relative to the new ones I find to be more useful.

I brought up the service menu, and for the total time, it had a value of 161. Can anyone tell me how this number can be translated into something more like hours or days or ??

[tom66]

Probably number of turn on/off cycles. So not many at all!

[Scenic]

Normally it's POH, Power On Hours. If it's on/off cycles, that should be easy enough to check. Just turn it off and back on again and check the number

As for the numbers (ESR meter readout) not being really meaningful.. If you look up the datasheets for the original caps, that might help (if you can find them that is..). If they're low impedance/ESR types, they should list the ESR/Impedance values for the specific voltage/capacitance/can size. If they're way off of what they should be, the cap is obviously bad.

Searching for the datasheets is pretty easy. For example, if the cap in question is a Capxon KF series, just go to google and search for "capxon kf filetype:pdf".

The "filetype:pdf" makes google only show PDF files as results, so you usually don't have to dig through crappy websites to get to a download link. The results after the first 3-5 or so are useless most of the time though.

But 161 hours... that would even be covered under a 28 day return policy if it went wrong that quickly!

[Scenic]

Might have gotten reset at some point.

When I was working on a Samsung LCD TV, it originally showed around 5900 power on hours.. after a factory reset it was 00000 again
(even though a factory reset shouldn't affect the power on hours counter in the service menu if you ask me)

I've had Samsung TVs ranging from just 2000 to 10000 power on hours - they never last long!
