Re: Hitatchi Ultravision rear projection **NO POWER ***
Usually, when there is no sound, it is because something is not set right in the menu. The fact that the set has shut off completely is quite common in that set. There is a little blue capacitor next to the horizontal output transistor that burns up and blows the small main B+ fuse. Those parts should be replaced by a qualified tech experienced in the Hitachi projection sets who will also check the settings in the menu to get the sound back.

Hey, I found this on a blogsite about lcd rear projections....looks like our tv's screens have been burned by the "pillers" that surround the tv when switching from 4:3 to 16:9 or fullscreen... read below, I hope it helps !
Rear projection crt's,the first generation widescreen tv's were notorious for that.Lcd and plasma can have the same problem,but it takes much longer and is not as harsh.Dlp's use tiny mirrors,so it isn't a problem with them.Lcd and plasma tv's should be ok unless you watch them with blck bars on them all the time. We have lcd monitors at work,and i've seen them after a year with bad burn in.They also run 24 hrs a day 7 days a week with the same display.

i have 51" sony rear-projection and those freakin' grey bars burned themselves right into the screen...
I read that to avoid the burning you had to limit your 4:3 viewing time to 15% of total time viewed. (applied to my TV but apparently yours and others as well...great! now they tell you :-x , this applies unless 4:3 aspect was changed to stretched or zoomed...yuck :-x )
This really sucks as a Star Trek/Lexx/Farscape fan as they are mostly 4:3, fortunately the upconvert player/hdmi combo sends a 1080i 16:9 signal to my TV so the effects are drastically reduced by nearly filling the TV without the grey bars or burn in problem without stretch or zoom modes being used. yay! :wink: (default grey bars set to black automatically, apparently grey isn't needed due to screen area covered is sufficient for burn in not to be a problem.)
You have a problem with the optical engine- The only repair would be to change the engine for about $500-$1,000 plus labor. This is a major repair (sometimes caused by dust particles getting on the LCD panels inside the engine, but disassembling the engine to try and clean it is not a reasonable option)
