My projector shows a blue tint to the right of the screen. I am afraid that it might be the blue LCD panel gone bad. What might the diagnosis be? Sony VPL-HS51


Does the blue tint show up as small rectangular pixel shapes when you get up close to the screen when focused properly. This would indicate a blue LCD panel fault. If it's fuzzy then possibly a blue polarizer overheating

Blue Haze on screen Sony cineza vpl-hs50 projector


Its your blue polarizer going bad. This happens over time due to the excessive heat generated in the projector. The main problem is that your projector has organic LCD panels that degrade over time and in turn degrades your blue polarizer. The same thing happened to my sanyo Z2. It took 5 years for it to show on my Sanyo because I only use the projector for sports and movies. not daily tv watching. In any case, it isnt worth it to spend the money ti fix it...jut put tat towrds a new projector. The latest crop of LCD projectors almost all use in-organic LCD panels that last much longer. Hope this helps.

This is for a different model, but I had thin horizontal lines in red and had to adjust the tube for red. You may have a similar adjustment on your set.

I had the same problem with a Sony VPL CS1. It's not the mainboard, but the blue filter - cost to repair runs around $500 US.
Hope that helps.

It's hard to say, based on your description, if your symptom is caused by the power supply or vertical circuit. Do you mean there is one thick black area that moves slowly up the screen ? If so, do you still have picture and sound while this is going on ?
