Question about Hitachi 51F510 51" Rear Projection HDTV-Ready Television
My hitachi is only one year old and the picture has been getting darker and darker over the last month. i have the setting as bright as it will go, but it is getting almost to dark to watch. has anyone else had this problem and if so, what is the fix?
I was actually out looking for another set until I read this. I fixed just in time for the Superbowl!! Thanks!
One thing to note.......The first thing I did on the focus block was crank up the screen adjustment for the red lamp (upper left) to see if it made it better or worse. This must overdrive it or something because I heard a faint "pop", then the screen shut off. I unplugged it, turned that knob all the way down, waited 5 min., then turned the set back on. The screen came back on and I slowly returned that knob to it's original position. Everything was fine after that, but I'd avoid adjusting those top 3 knobs.

I have the same model with the same problem. i just paid a repair man to fix it. he adjusted the focus block. if you remove the lower front panel, then remove this other access panel under that there will be a block with 6 knobs on it to the upper left of the access port. 2 for each projector. play with the knobs till you can read the menu options again (mine was so dark i couldnt). then turn your color all the way down till its black and white. then adjust them until you get a nice perfect even gray. then turn your color up and adjust your settings. thats it in a nutshell. it took the pro about a half hour or so. if it takes you longer dont feel bad. i hope me paying for this service helps you guys out.

The screen/focus block assembly has caused problems with this model in the past. Sometimes it can be readjusted, other times replacement is called for.
