OK.. These are photo-sensors for auto-convergence function and without these sensors, auto-convergence function will not work properly.

How much is the inside glass behind the screen


Hitachi has two screens (other than a clear screen protector some have) The two inner screens are only sold as a pair---over 400) If the mirror behind them is damaged look to see no glass has scratched the inner screen as it will show---Mirror can be available either from Hitachi or some after market places have them.

If the mirror--Google the model number with "replacement mirror"

I was wondering if u know y my mitsubishi tv wasnt showing a clear picture i replaced the lamp with new one but it still shows a dark picture


This may be a model that has two mirrors. Mitsubishi could tell you if this is the case.

Some idiot had the bright idea to have optical unit shine picture into tiny mirror which puts it into large mirror in back; problem is tiny mirror if there is at bottom and facing up, dust or dirt get on it and picture brightness will diminish up to 70% or more.

If model you own does have two mirrors, the front of the set with the screens will have to be removed to clean it, not real hard and takes 15 minutes.

If you can confirm it has two mirrors I can tell you step by step how to remove screen unit and resolve problem. Usually if tiny mirror dirty it will happen over time, picture will gradually get darker and dull looking.

Let me know if want instructions, the set either has two mirrors or it does not.

How do i set up surround sound on a hitachi big screen tv model 51f510


On your jack panel in the rear of the set look for the Audio Output Jacks. They will be Red and White. Just run the cables from there to your Aux Audio Input of your surround sound receiver.

My mirror is broke in my big screen do you have to buy a special mirror or can you use any mirror?


The mirrors are specific to the unit as they have slight curves to bend the picture correctly so it aligns to the screen properly. To ensure you get the correct picture for your unit, you would have to order the manufactures original replacement part. You can order an new OEM replacement mirror for this model (53SBX59B) from a major Hitachi parts distributor at the link below:

Bluish hazy texture on my screen


It sound like the light engine is going out or already out. I would take it to a certified Hitachi dealer have them check it out then I would call Hitachi to have them fix it for free.

50 INCH HITACHI ULTRAVISION HAS COLOR DIFFERENCE ON EDGE OF SCREEN


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.)
