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 !
cheers!

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.



GKar posted 2006 Oct 10 15:31 TooLFooL : 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.)

Hitachi projection tv quit


Pls check that model number........the problem description does not match that of a 1999 crt proj tv.........I believe yours is a newer lcd projection around 4 or 5 yr old?? Lamp light flashing on any brand is indicative of the lamp not lighting . The lamp is the most likely cause,but the ballast board can cause this as well..................you should see an access door refer to owner book of the correct model and you can replace yourself...........it may cost around $200 and avaiolable at encompass parts .com Hitach distributor

My 61" hitachi rear proj has a very dark picture.


It sounds that lamp in TV is weak and not throwing enough light to bright the screen for good image.
How old is this TV and did you replaced its Lamp recently?
If lamp has not been replaced yet or in last 2-3 years, replace it.
