Question about Brother PC-420
It seems to be a backlight issue and it would need replacement.You could contact Brother for the backlight. It is tricky to replace backlight ,however you could replace it if you have prior experience repairing these machines. Once you replace the backlight, it would solve the problem.
As for the actual replacing of the part, there is a great deal of delicate work to be done in removing the front panel and "A" Board to gain access to LCD Board, it would best be done by a service technician with the appropriate Service Manual......but you will need to source the part first of course.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
