Opaque projector takes an opaque object and through a system of mirrors and prisms it enlarges the objects and projects it into a screen or a wall.

the light tunnel likely has collaspsed. a collasped tunnel isn't adjustable.

its not the bulb problem . the lcd block need sto be replaced , better to buy new projector

Something I found interesting from the internet - lamp life isn't when the bulb dies, but when a bulb has lost 10% of its brightness - so you might well be able to reset the timer and get much more use from the bulb - the image just wont be as bright.

The lamp may not have been changed - just the timer reset - How many hours has the lamp really done - 1000, 3000, 5000?
If you know that the hours are genuine, then was the quartz bulb contaminated with a touch of oil from skin contact?
This will substantially shorten lamp life, due to the quartz going milky and opaque.
The easiest way to check, is to pull the lamp and have a look at the bulb.

If need be replace the lamp and reset the lamp timer.

These instructions are for a Sony Cineza VPL HS3, but may be the same for the HS51
1st thing to check - is the cover properly/completely closed - this can stop the projector from working.
Connect the power and set the projector to standby mode.
Press these buttons on the remote control in this order, for less than 5 seconds each.
Reset - Left Arrow - Right Arrow - Enter

Probably just a burned out bulb. Look in your Yellow Pages for a Minolta Dealer or Google...Minolta MTP101 bulb / lamp.

unfortunately not. the discoloration is caused by the light filter getting fried due to excessive dust and heat. and you cannot purchase the parts individually. you'll have to replace the entire optical engine.
