You shouldn’t really be powering the console or leaving the battery connected at all if you know there’s bent pins in the LCD connector. a fair few lines here are going directly to the SOC, coupled with the various voltage rails also present on this connector and it’s asking for trouble.
It’s quite possible something is getting pulled high or low that ought not to be because of the bent pins.
I’d first attempt finding out what the pins are, you might be lucky and find they’re no connects or a redundant grounds…In which case you can bend and snap them off (for testing purposes)
If not, I’d remove the connector entirely and replace later.
You can also check backlight ribbon contacts and also carefully measure the voltage on backlight connector pins
Though if i remember correctly certain lines have to be present with the LCD/ribbon connected otherwise backlight voltage won’t boost
I mean i would replace it regardless but if you just want to see if you can get it working temporarily you can attempt to follow the below instructions, theyr’e just copied from another post of mine in another thread, but same issue.
seems risky to me (or my skills :)), I’ll wait for the connectors.
what is the best way to swap the faulty with a new one ?
I have a hot air station, good quality flux, but no binocular or fancy magnifying stuff (I use to control my solder joint with my smartphone and its numerical 7x zoom after).
