T2x LCD screen/cable issue

[synchromesh]

I have an older T20 chassis with a bad LCD screen. After doing some testing I realized LCD panel itself is bad (there was an inch-wide stripe that wouldn't go away) so I bought a used LCD panel on eBay. The rest of the components (inverter, cable, plastic parts, stands, etc) are being reused from the old screen.

Here is the problem: when newly assembled it worked just fine but after a couple of times closing the lid the cable would pop out on one side on the LCD connector making the screen show some wild colors and not much else. Reconnecting the cable to LCD panel would fix the issue until next time. Obviously cable was too short so I did some research.

I found 4 different cable FRUs were used in T2x series. One was for 13.3in screens, another for SXGA+ panels. Since this one is neither, they were out. That left me with 2 choices: 0519 from T22/23 or 0640 from T20/21. The one I had originally was 0640. After buying a couple more of those by accident, I realized they all pop out. Then I bought a 0519 on eBay and voila... same exact thing.

So now I'm kind of stuck with a bunch of useless cables and a basically non-working machine. I can't figure out what cable must be used. Oh, the LCD panel is a Samsung 141x5124. The connector does seem to be sitting a little higher than on other panels. I asked the original seller and she claims it's from a T23 but doesn't know the cable FRU number.

Anyone has any ideas or experience with these panels/cables for them?

I suspect you've had some bad luck, originally had a 13.3" XGA LCD panel and replaced it with a 14.1" XGA panel. Presumably (I have no experience with the smaller panels) the original cable was a trifle too short, giving you the problems you mention. Replacement of the cable by another 13.3" panel cable wouldn't help in this situation, and to my knowledge, the SXGA+ panels use a different cable, so that wouldn't do either.

If my above assumption is correct (originally 13.3" panel replaced by 14.1" panel), I'm a little surprised you managed to get the panel to fit in the housing, and if that's really the case, the housing dimensions might be your basic problem rather than the cable.

Since the 14.1" XGA display was apparently the most common in the T2x series, and the housings/cables fairly cheap and easily found, it would probably be best to get a 14.1" housing (and XGA cable, if necessary) to match the panel.

All of this goes on the basic assumption that you originally had a 13.3" display. If that wasn't the case, we'll have to rethink the situation. But maybe that will help a bit to start.

If you don't have the HMM yet, you might get it for reference.

I've seen the 13.3in enclosure. While the lid is the same, the inverter, cable and and screen stands are different. There is no way to fit a 14.1in screen using 13.3 stands. It just simply won't fit.

Either way I have a couple of 14in enclosures laying around. The original bad screen is a 14 incher too. Incorrect size of screen is a very unlikely culprit. The problem is definitely cable/LCD screen connector.

Several times i changed FRU27L0640 against a "dead" 27L0519
and i can assure you that this two versions have exactly the same physical dimensions and are interchangeable
Same thing with all original T2x 14.1 lcd panels.
Assuming that your cable is in the right position
the only thing thats left for me is that the panel you bought fom ebay is not compatible,
it`s the: "a little higher" that makes the point.

by the way, i have a 1171-337 i series with the same issue, but intentionally ;)
the original lcd was broken, and it had the typical crack in the lid near the left hinge.
With no hope to get a spare lcd for a reasonable price
i checked that a 560x svga lcd had the right connector for the cable on a slightly different point,
the same with the screw sockets which i removed,
fixed some from a broken case on the the panel and glued them into the cover.
Last thing was to lead the cable out of the lid in a direct way so it could reach the connector on the motherboard.

IF the screen and cables are interchangeable with the T23, I could offer you either the cable or the screen (or both) if you're interested.

Message me if interested.

the LCD panel is a Samsung 141x5124

I'm almost certain that your screen isn't an IBM part.

Looking up the Samsung model number I found it is a screen for Compaq/HP, I haven't found it listed for IBM.

If it's an IBM part (and IBM did use Samsung as one of it's many suppliers) then there will always be a barcoded sticker with "IBM"
in bold print and the FRU#.

If that's not the case then you should contact the seller.......

Yes, I came to this conclusion too after failing to locate an IBM FRU on the screen. Problem is I bought this 2 months ago now so I doubt the seller will return my money. Of course I can try.

The only other fix is to use a good amount of tape near the LCD connector which then precludes the cable from popping out. But this stretches the cable every time lid is closed and is only a temporary solution I reckon.

Sorry to hear that your stuck between a rock and a hard place. Is the seller still selling screens? If they are, maybe they would argree to an exchange if you plead your case. It works but it's not the right screen. It's worth a shot..... an ounce of effort is better than a pound of tape.........
