There are many ways a home cinema viewing experience can be improved. These rules can be applied to existing home cinema installations at minimal cost as well as applied to new home cinema installations. It may not be possible to apply all the rules in every residential installation but the more you can accommodate the better your viewing experience.

I have an old 46" LXI rear projection television and the green light keeps turning off. How do I fix it? Also is there any online manuals or directions?

This is what the sticker says inside

Green light turns off is usually just bad solder on the CRT board….resolder it.

If it still acts up, then measure the HEATER AC on the CRT, the 200 V supply, make sure the Cathode is running at 160V to 180V and the Screen voltage is around 300V….that will isolate the problem.

My screen is displaying pink & green swirls on the top of the screen as well around objects.
Of course I tried turning it off & on as well as messing with the color and picture settings. I have zero idea what this is or what I can do about it. Help!!

Those swirls are caused by NOISY convergence amps…

They need to be replaced, and in most cases, you are looking at $380 to replace them.

But the GOOD news is….that’s the ONLY problem that you’ll have with that Hitachi Projection TV set…..

They are that reliable….
