Question about Hitachi UX21511 Projector Lamp for 50V500
When my screen goes blank between shows or the show is real dark you will see the pink circle in the middle of the screen...otherwise it is a great picture still and I have owned this tv forever....and nothing else has happened to it.
That model isn't known particularly for this, but on many other
similar moels this would indicate a warped light engine causing
distortions in the picture. It may be just starting to happen in
your set and since it is caused by overheating of the plastic housing
of the light engine ($$$) you should clean the filters of the
ventilation fans and make sure it is getting cooled well. Also,
projection lamps get hotter as they age so it may be part of the
problem as well.

The Problem has to do with the light engine and apparently its a known issue and I would contact Hitachi on this one. If you complain enough and play your cards right they might give you a new tv or repair it for free even if its out of warrenty.
If you have a uniform pink hue on screen: turn television input to input channel that is not being used (should have a blank screen) shut tv off. Have television off for 2 minutes hold input button and turn on television. Let go of button after5 seconds. Television will have service menu on it. Hit menu on remote, this should bring you to 2nd page. Scroll down to Mem init box w/ remote. Hold joystick button to right til check mark is seen on square for mem init. Let go of joystick and this will re initialize memory. This fixed my pink hue issue and I did not need light engine. Remember to change your input to that of an unused one. Otherwise you will not be able to reinit memory.
