Why after i replaced the bulb the picture is still dark?


Are you sure you put the right bulb in ? These need a P22H 120 watt bulb. You CANNOT use an E22H--it has the wrong optical angle. it will work--but WILL be dark.

I have a hitachi 50v710 I replaced the bulb now it wont work


EASY THING TO DO HERE IS REMOVE LAMP and see if it went in perfectly---when you have one problem--then replace a part and have something different usually something happened when you replaced the part.

It is always possible the new part is bad but you should have a different indication of some kind.

I have a Hitachi 50v710 it has a yellow tint in the middle of the screen can this be fixed thanks


This tv is an LCD projection one. in it the image is generated this way: a bulb makes the light; this light is divided then passed thru 3 small LCD screens; the 3 pure color images are mixed together by a prism then passes thru a set of fine plastic lenses (this is called the optical engine) ; from there the final image is projected on a screen.
The entire image quality is determined by the quality of the optical engine - if something goes wrong with it it's clearly visible on the screen. In your case the heat of the bulb has deformed the first lens, and that has caused optical aberration - color shifting.
This is fixable, the optical engine will have to be replaced - you can't replace just a single lens, it's a sealed unit. Unfortunately it's not a practical solution: a new optical engine will cost you over $800.
Use the tv as is until you can save enough for a new one.

Yay my whites are now yellow


That is a defective light engine and would cost more to fix than to replace..Sorry to hear the bad news. This comin from a former Circuit City TV technician.
