Hitachi tv model 57f510 screen stays green - Hitachi 57F510 57" Rear Projection HDTV-Ready Television

If I remember correctly, There are 3 projection globes in the back of a rear projection TV. I would say 1 of the globes has failed which is gives you an incorrect colour balance on the screen. There is usually a red, green and blue globe. Its probably either of the blue or green one which has failed. Someone else on fixya may be a bit more conversant with rear pro TV to confirm this.

It may have to do with the Magic focus if that model has it: auto convergence and if fails a indication can appear on screen. The Magic focus if in play would be a flashing sequence moving to different areas of the screen in sequence.

No reset on this model---if no power light at all begin by following power cord in to the set to check the fuse.

Set should also have several green leds that have to light.

cannot repair. it is a cosmetic blemish. you can replace front panel but is usually not economical to repair.

yes if you have a blue vga input on your tv. or if you have an hdmi output on your computer. also please eleborate if you wanna run this as duel screen or not if so i can give you step by step directions on how to get this to work

You may well have either poor contact on the tube base of the colour that is missing or a poor contact in the tube itself. The latter is not repairable.
