Hello.
Question for the repair shop.
I replaced the screen on a BQ Cervantes 3 e-reader that had a broken screen.
The original screen on this reader is ED060KG1, but the seller I bought the replacement from sent me the ED060KC1 and assured me it was 100% compatible.
You can see the result of the replacement in the attached photos; the image is reduced.
The touch screen works, but at full screen, not like the image.
The light also works.
The resolution of both screens is the same.
I no longer have contact with this seller. Do you see any solution?

No, it's obviously not the same part, and also obviously not compatible, unless the cable connection or socket was damaged, or isn't mated correctly.

I would like to know which ebooks this ED060KC1 screen would be compatible with, as I believe it is in good condition.

The multiple lines at the bottom of the screen certainly look like the sort of artifact you get with a broken screen, also why do you have a partial sleep screen on the left but also what looks like a wake up screen/ start screen on the right?

If you bought this from somewhere like ebay I would contact them about pursuing a refund if possible (although if the seller has gone quiet/ disappeared that may be difficult)

It almost looks like a 1072x1448 screen displaying a 758x1024 image. OTOH, the spec sheets say that both the ED060KC1 and ED060KG1 are 1072x1448 resolution panels. Was the Sleeping on the screen there when you received it?

Might also be a loose/dirty display cable connector.

Broken means Not functioning correctly. Flawed in some way.

But were there jumpers that needed setting.
My original Astak needed a resistor change on the main board to match a calibration number printed on the display

I originally bought this screen for a Kobo Glo HD, which shares the ED060KG1 model with this BQ Cervantes 3... but I received the ED060KC1.
I wanted to try it on the BQ first. I suppose it wouldn't work on the Kobo either.

I think it's too much for me
This is the main board

I have no idea bout YOUR device or even if it does have that type of setting.

My comment was a 'general' possibility to research in the manufacturers repair documents.

SMD boards do not always have obvious jumper, but might use 0 ohm resistors (and have R# designations instead of JP#)

for even attempting a self repair

The lines on the bottom of the screen looks like a broken substrate.

Have you tried making sure the ribbon cable is installed correctly?

A broken substrate is noted for curved lines. Controller/cable issues are noted for straight lines.
