Unplug it,then wait 10 minutes,then plug it back in.

Thats almost alwasy a Tconn issue replacing the Tconn board should solve the issue in most cases you can get replacement T conn from www.tvcircuitboards.com

Based on your information given maam, I can say that your LCD is not working well but sometimes it happens that there is a problem on its connection to circuit board..This is usually I encounter maam as a most experienced technician.Thanks.

Hello Sashaone,

The F3 has the most extensive selection of focus screens ever made for a Nikon camera - 22 in all. The "L" and "P" will give you the diagonal split image rangefinder that you love. The difference is that the L has a groundglass/Fresnel lens field around the split prisms. The P has a microprism collar and an inscribed horizontal and vertical line forming a large cross.
You should also be aware that with slow lenses with maximum apertures of f/5.6 or so, these prisms tend to black out. Here, Nikon has solutions too, including the R screen, which has gentler slopes on the prisms to combat blacking out with small maximum aperture lenses. The R also has grids to help with composition, similar to the E. Then there are the all matte, all microprism, aerial image screens (C, M) too.
Personally, I have the C E K M R screens, in alphabetical order.
Some subset of these screens are available for the other Nikon F series cameras (F, F2, F3, F4, F5, F6), as well as the FM2, FE2, FM3a line, which can also interchange screens.

Thanks.

Hello,
Since I do not have a picture of your screen, I can only guess. If it looks something like on the figure below, that can be fixed.

In the foregoing picture, the screen is split horizontally. The black cursor is in the lower half of actual screen. You can restore the full screen by pressing [MODE], and scrolling down till the last line Full Horiz G-T. Move cursor on Full and press [ENTER]. Then press [CLEAR] to go back to the main screen.

If I did not guess right, well I am only human.

You need a new lcd screen & while at it replace the inverter.

Hello,
You need to adjust (actually bit decrease) G2 volts (calls Screen volts) of Blue gun.
If you are familiar with big TV repair and have electronics knowledge then let me know to guide you further.
thank you.

interference in the wallsocket, try plug the unit in separate outlet! if nothing happen you're dvd have leak capacitor on the power supply board to filter the interference!

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.
