| I’ve seen a few other threads suggesting vertical lines on the display was a h/w issue. My device is fine until I insert a CF card. The vertical lines show for the duration the card is in the slot, but everything returns to normal when the card is removed.
I think the card should be good, formatted FAT16, 16kb cluster on CE 2.0. All the pins internally seem true as well.
Does this sound like a card issue or is it more likely a hardware issue with the device?
Many thanks!

| To troubleshoot, do you have another cf card to try? Or something PCMCIA? Hard to tell if the screen is on the cusp of blowing out that line permanently while now simply making it visible only if there is an extra power draw.

| Also, does it happen on both AA battery power and also when plugged in to ac adapter ? |

| Thanks so much @Jake, @Torch for the input, yeah the vertical lines happen both using the adapter and under battery power. Currently I’ve no other cards nor PCMCIA to rule that out, just happened to have this 128MB card lying around which was on the compatability list.
Would you have any suggestions for what I try next?? I was just trying to determine how to best move stuff between the PC and the 320LX |

| I'm assuming you don't have a serial cable.

| Perhaps post a small photo?
The obvious electrical answers would be that there is a capacitor on its way out
It's electrical noise
Some sort of minor short
It could be worth a tear down, clean it up and put it back together - just be careful, slow and methodical if you try it. |

| How about cleaning the inside of the PC card slot first before tearing the whole device down? Maybe dust or hair or something could be clinging to one of the pins? |

| Its a cap on the mobo. Almost positive. I had something similar happen with my 300LX back 20 years ago. Practice on something else with your soldering iron first. Take your time, i repeat, take your time tearing down the unit. A lot of easy to break stuff if you are in a hurry. Also the plastic has become brittle on these older units, so dont force pulling stuff apart.
If you cannot find the cap to order, let me know. I have a spare mobo i can take the part off if ya need it. Its a 360LX, but im pretty sure the same value was used in the 320LX. |

Not to discount what was said by the others but I highly recommend trying this suggestion from @CE Geek first. Just to narrow things down and focus on what to try next |

| HP 360 LX in pieces
I'm not an expert I electronics, but the screen ribbon is in the opposite side, and there's no piece in the way of the CF card. Could it be a bent pin in the slot? |

| Many thanks all for the suggestions!
@C:Amie pics, the lines consistently go on removing the card.

@ABBADON, to you do the pins *seem ok??
Pins
@CE Geek, @torch, yep that’s about the limit of my investigation skills - my electronics expertise peaks about the level of blowing dust and fluff out, I ordered some deoxIT in case it might be something straightforward.
@WallyB110, yikes that’s what I was worried about - my past history of turning teardowns into bricks is illustrious hahah, I think I’d have to have made my peace with the little fella before I opened it up!! |

| That is worse than I was expecting. Are the patterns consistent? I'd guess that the card is drawing way too much power or there is a short.
Does the CF card work in anything else? |

| @C:Amie Hey, thanks for the help, and that’s an interesting question. I hadn’t noticed before, but yes, each time the card is removed and inserted, it shows a different pattern of lines...
lines1
lines2
lines3
With the card removed everything functions as expected. Otherwise, the card itself reads ok in Windows, and partitions, formats etc. in Diskpart via a card reader. Edited by Iiw384 2024-03-11 7:52 PM
