Blue outline on the top half of the picture on my Hitachi 51F500

I have a blue outline on the top half of the screen and a wavey blue line at the top. I tried to manually adjust the Magic Focus but I can't get the blue lines to line up with the grid.

Red wavy lines at top of screen.


Rear projection t.v.s work differently than most. They have threw lights that throw the picture onto the screen, instead of having a color tube that is in a traditional television. It would be my suggestion to bring it to a Qaulified T.V. professional to have watever bulb is bad replaced. odds are it will either the blue or the green(hard to remember exactly but i think its a green one lol) and not the red.

HITACHI 53SBX59B, projection lights don't line up.


It sounds like bad solder connections in the convergence output circuit. It may also be an intermittant convergence output ic which will need to be replaced.

Hitachi 51F500 (Two separate problems?)


My guess is that the sound you heard was that of some High Voltage discharges that could have fed back and damaged some semiconductors including the microprocessor itself. Since it could be a very expensive repair, I would be very tempted to look around for a new HDTV by JVC or Toshiba. Hitachi has slipped a notch or two in recent years according to my experience.
