Lines missing on 3310 (not elastomer fault) - GSM-Forum

Blartiartfast · 04-10-2002, 03:42

Nokia 3310, alternate horizontal lines missing. Changed screens, etc but still no joy.
Any ideas??
Thanks.

THEKILLER · 04-10-2002, 05:28

oh yes, the ideia is replace the display by a new .

Blartiartfast · 04-10-2002, 06:58

Thanks for that, but like I said it is not the screen, or the screen connector. it is not a bad connection between the main board and the screen.
I have also had the board in an ultrasonic bath for an hour, and the fault is still there.

Any other ideas anyone

I have seen this before. Unfortunately, i didn't have time to look at this phone.
I suggest you get another 33xx to compare continuity and check for broken tracks on the LCD pads.
Also check BGA chips for dry joints (reflow BGA's if you can).
Not sure but this could also be linked to LCD.

The one i saw with the same problem you have had also been in ultra sonic tank. must have had water damage.

Thanks.
I'll reflow it again later today.

Hi,
I had same problem with a 3330, problem solved by changing screen for one made by different manufacturer ( I think that nokia use screen from 2/3 different manufacturers (philips etc) on 3310/3330.
You can tell difference by looking at connector.

Regards

Thanks. Hadn't thought of that.
I'll go through my extensive mobile graveyard and try a few other displays

@blartiarfast

your first post said (not elastomer)

i have changed dozens of 33xx displays but never seen one with an elastomer, all the ones i see have contacts (pin type) so changing the lcd does seem like a possibility.

Blartiartfast · 05-06-2002, 19:58

Sorry for any confusion, but when I said elastomer, I just meant the connector between the screen and the mainboard. I said this in an attempt to cut down useful replies to the fault requested that I have already tested

mujie · 05-06-2002, 20:06

best solution is to try and change v100

Check connection betwen
C413 and C409 to 1 pin LCD
and
C410 and 412 to 7 pin LCD
If no connection -alternate lines
Check PCB near capacitors
