A lot of blue (or any color) dots suggests a optical issue---depends on model number.

SOURCE: Hitachi Ultra Vision 61UWX10BB Will not power up Red led flashes

Your repair didn't address the failure. It is much more likely (in the absence of video and sound) that the power supply has failed.
The items you replaced affect convergence and have nothing to do with the audio section or the set's ability to receive signal. The power supply failure will diasable everything.
Look for a separate board with larger-than-average components, some cylindrical (capacitors), some block-shaped (chokes and transformers). And you may be able to recognize its relationship to the AC input line.
Locate the assembly number which may be on a paper label or just printed in ink on the board; any that appear to have been part of the etched traces will be only the empty board number, not the assembly.
Removing and replacing this assembly can be done by most everyone using a little common sense and just plugging in the connectors where they belong. Call your Hitachi service center and ask about potential repair or replacement costs. If you can score a new board, don't throw away the old one since the new board will be as crappy as the original. This way, you will have time and opportunity to find an independent reapir service for these and have a spare on hand for . . . sorry, the next failure. These things aren't 'your father's TV', they die much more often.

Yes, I do. It needs a new light engine. Very costly repair. However, Sony has extended the warranty on many of these LED projector sets. You need to call a local Sony authorized service center and see if your model is covered. Otherwise this repair could run over a thousand bucks.
