Question about Zenith E44W46LCD 44" Rear Projection HDTV-Ready Television
Had the Light Engine replaced (yellow blotch on whites and 4:3 burnin).
(This is actually the larger TV M52W56LCD)
With the new LE, there is a moderate pincushion effect.
Now vertical lines aren't really vertical. Crosshatch image shows curvature at the top and bottom.
Service tech wasn't any help. He fixed the alignment of the engine, so the picture was correct on the screen.
Could this be an issue with the mirror? It was smudged and cleaned when the light engine was replaced, could it be curved somehow? I don't think so, because the curvature is symmetric.
You did not mention that this cost any money, so I assume that this was a warranty repair. There is the possibility that the new light engine is defective (I see it all the time), or TV needs adjustment via service menu, not mechanical. Call company back or call manufacture to get another company in your area to come out and repair your TV properly. Don't quit until your TV is working properly. Good luck.
