I have a Hitachi 43FDX20B that has sound, but no picture. It only shows a few groups of horizontal lines (about 10), and you can see the individual red, green, and blue lines in each group.
I have a lot of experience with electronics and replacing parts, but I have never worked on a TV like this before. I'm looking for a copy of the schematics so I can start checking to see what's wrong, but any advice would be greatly appreciated.
Thanks for your help.
