Question about Projection Televisions

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

My hitachi ultravision now has no picture usually. it used to have a picture as of a few days back, but then it started to all of a sudden have just one line across the screen (hirizontally). i noticed that if i banged the back a bit the picture would come back. now however the screen is almost always black. the sound is ok. im thinking something is loose but i dont know.
the television is an ultravision i think around 45 or so, its about 5-6 yrs old.

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.

The best guess is likely convergence control IC's (2 of them STK392-110) and associated circuit problem.
It's acommon fault which causes the symptom you describe - get an estimate - usually between $200-300.

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.
