I have replaced the battery as directed. The display lit up, with a blank screen upon powering up…but that’s all. After approximately 2 minutes it beeped twice, and there were dark bands on the lower area of the LCD display. Now it just beeps every 2 minutes. After being plugged into a charging dock for 30+ minutes the lower half of the display has alternating bands of black and dark grey, and is still beeping twice every 2 minutes. I used a soldering iron that was not calibrated…might I have fried the pcb?
The problem you describe is due to damage to the screen. The beep you describe maybe that replacement battery that is not good .. If I were you I would try to change the screen display, do not think that damage to the PCB because it lights up.
