Hi.
Background: LCD was not showing an image at all, an issue with the speaker, and also the battery was inflated. I ordered a new LCD original(just LCD) unglued the old one and tested it all the time with the new LCD. When powered on with or without battery it shows a picture, sometimes it goes to log in(with battery) and works for a bit and then turns off, and sometimes on loading, it will just restart. When it restarts sometimes it will show only the backlight, sometimes nothing. I found corroded CB 211 and removed it and also the row of C3523 near U3500(resoldered all of them). I have replaced U9850(donor board), but still the same thing. I tried also a new battery just in case. Note with the old LCD doesn't show a picture at all I tried it again after I tried with the new LCD. I noticed on the thermal camera it heats up around 55 degrees L7030 and Q7030. Also, the chipset sometimes goes up to 55-56degrees.
Any ideas would be appreciated
