I had similar problem with my 57xwx20b TV as well. I'd unplug it from the wall for at leas 30-40s and plug it back in, the picture would return as normal. It will come back from time to time but the same procedure will reset the video board and the picture will return. I'd also check to make sure that the TV has the latest firmware from Hitachi as well. The FW for the ATSC tuner is upgradeable via the SD card and Hitachi website will give you the procedure. This fix all kind of problem with my TV from blank screen, green screen, flashing screen, pinkish screen because the old FW was built before the final standard. Apparently, it interferes with the video board and causes it to go amock. Good luck.
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.
I own a One-for-All universal remote and my booklet says the setup code for a Hitachi TV ( without a built-in VCR or DVD) is 0145. I do not know for sure, if this number will work with your remote, but it is worth a try.
You may need to set your screens look at the picture when you have a real dark background if there is faint lines in the picture then the screens should be set correctly
There are lights on the board about 8 you should look at which comes on and which stay on this by hitachi standards tells you what is wrong. Most of the time its convergence amps bad.
