Sony KDS 50a2020. Tv Seems to Dull. not a setting.


Two possibilities:

1. The lamp. When did you last replace it? They will dim over time and lose focus, clarity, brightness and sharpness. If it has been 18-24 months, and this is your main tv, consider replacing it.

It's a F-9308-860-0. They go for about $175.00.

2. Let's say you follow my advice, put in a new lamp and the picture is still dim, dark, dingy and fuzzy? Then you, my friend, need a new Optic Assembly. The thing your lamp shines into and the thing that gives you a picture to look at. They can fail or wear out for all sorts of reasons--too many for me to type out now. But, suffice to say, if you have recently replaced the lamp (less than 6 months) and are experiencing a drop in brightness, consider getting on the phone with Sony. Even if you are out of warranty, your set is covered against Optic failure until June 30, 2010.

Hope this helps.

Blue and Pink spot on my Panasonic Projection LCD


Panasonic didn't release a 61" LC13, are you sure that you dont have a PT-61LCX65, 35 or 15. If your model ends with a 5, call 1-800-211-PANA (7262) to schedule service, they have a fix fuzzy the fuzzy colored spots they are covering under warranty.

Fuzzy Picture


Fuzzy is a funny word. I never use it to describe a picture problem. That because fuzzy can go too many different ways. There is snowy fuzzy, blurry fuzzy, grainy fuzzy, and demodulated fuzzy. If the set goes out of focus intermittently that has something to do with the focus ciruitry. If it goes grainy that is a front end problem, usually tuner related. The other types of fuzzy are generally associated with problems in video processing some where. So, which is it?

Oh, and BTW that unit has three small picture tubes in it, one red, one blue, and one green. It doesn't have a 'bulb'.

Color issues with Hitachi 60V715


You likely have a problem with your Optical Engine. It is very expensive to replace and should fix the problem. The lamp cannot cause color issues. You may have dust/dirt contamination in the engine and it could be clean by a servicer or technical person. The blue LCD panel or polarizer may have failed in the engine giving you blue and yellow (lack of blue) type symptoms.
