I have i hitachi ultravision that has a green line and makes double faces

If the convergence is so far out that you cannot adjust with your customer access menu then You will probably need the convergence ICs replaced & possibly a fuse or resistor or 2. Then a complete convergence will be necessary & I HIGHLY recommend having a professional technician perform this task.

Many thin black horizontal lines on my Hitachi Ultravision 50" TV

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

No picture or just one line across screen on hitachi ultravision rearproj.

Could be a loose connection on the printed circuit board in the Vertical deflection circuit.
You would have to have a qualified technician to repair this problem.
A intermittent connection in the circuit described can cause a horizonal line across the screen.
You have to be careful and not leave the TV on for a period of time with a bright line, as it can actually burn a line on the CRT screens, which is permanent.
