x61 Tablet touchscreen doesn't work

[fab2985]

hi ,

you saw good . i find the fuse F6 ,it's for the finger print and it's F7 on my systemboard (out) .

I don't find the F1 fuse .it's not my systemboard ,the mine is x61T . it seem but it's not the same

The fuses are different from model to model and not all are numbered from "1" to "10" etc.

I own a T61t since xmas but i never had opened it

Measure the resistance between the tow soldered ends of the fuses. If  "0" the fuse is ok, if  "1" or "endless" the fuse if damaged. A new fuse can be soldered onto the old one but it must have the same Ampere-value.

so F6 on the picture have got the same Ampere-value than F7 on the system . is it right ?

i don't find the fuse F4, , there is write

Can you make a high resolution pictures from top and bottom in very good quality, upload it to imageshack.us and post the link? Maybe so i can help you seach the fuses

look the fuse f7 near the connector and the button battery .I think it burned

You'll need to measure the resistance of the fuses between their metallic narrow sides: 0 Ohm = fuse OK

ok , i don't know for the metallics fuses. i check the fuses f5 & f7 ,f2 and f4 (0.004 & 0.008) it' s ok on my system board . F4 --> F11 on the pic , F7 --> F6 , F5 --> F5 ; F2 -->F3 after where 're the others ?

On the bottom side of the board also are a couple of fuses.

If the fuses are well, the error seems to be in the display cable or display/digitizer itself. I hope, the pen is well.

hi , i continue with the fuses on the other side . The fuses are around the dock connector (F11;F13;F15;F12) and are OK .It's the same for F14 (between cpu & vga connector) I don't find the F1 fuse , is it missing ?

look this pic pls

On a X61 (not "t") - board the F1 - fuse will be found near the battery-connector - there is a "F" on the fuse.

That fuse seems nothing to have to do with the display.

So - if no fuse is damaged, no chip has a visible damage the error might be found in the cover (display, digitizer, cable) but i'm not very sure.
