    You got the same effect as removing defective side tabs from one side of the panel, it's better to insulate the voltage going to the bad side to avoid more sparks and damaging whatever supplies that voltage. That can be done with tape cut-off, search the forum about it, but I don't know which pins would need to be taped, needs to be trial and error or with a service manual pinout.

      as a last ditch effort, you can cut off the defective tab too.

            place it face down

            where the speaker grills are there are small holes at the ends.

            insert a rounded (8-10mm) wedge and press until the rear cover moves.

            drag the wedge to the side (away from the speaker grills) and start popping off the rear cover clips.

            the corners + middle top have adhesive pads.

            I used a long knife here to cut the adhesive pad before continuing with the wedge.

                    yea they are half circles, try to use something thinner at one end and thicker at the other.

                    sadly, to start, you have to just push it in (carefully as you can). Once inside, you can lever upwards to start detaching the back cover. It will be loud as it comes off, sounds like you're breaking it. Only advice is to be careful :/ and when you get to the corners where the adhesive is, open the gap wide enough to shine a light inside so you can see the adhesive and cut with a knife.

                        Yea it’ll be difficult. You might have to go over the same side a few times until the whole back starts to free off.
