Yamaha PSR-2700 faulty LCD display repair tutorial

** BATTERY CONNECTOR ** - https://s18.postimg.org/7g3g4c6eh/bat... One day LCD display of Yamaha PSR-2700 stopped displaying text It was still backlit in green, but there wasn't text displayed. So it was difficult to see what parameters are set for song. I have found similar problem for this keyboard and possible solution http://www.yamahaforums.co.uk/forum/v..., which I have tried. It came out that 2 capacitors on back of LCD display were faulty. Also the keys were not smooth anymore and I've fixed it. Volume knob also was adding some scratches during operation - fixed. Disassembling took about 1 hour (with making pictures).
