TOSHIBA 57LX177 SHADOW SPOT CENTER OF SCREEN


If my research is correct you recently replaced the lamp and then the "shadow spot center of screen" appeared.

Three possible reasons I can think of for this:

Something wrong with new lamp or on face of lamp--never touch the face of a lamp as oil from you hand can leave a residue and damage the lamp or cause a image issue.

Something inside on the optical lens or even the mirror causing this--not likely but possible.

A defect in the optical light engine in the set---usually if heat which comes from the lamp damages the engine it will be a color and not black---engine has a series of lens and baffles inside that heat can damage--causes minute separation inside of the lens etc.

If the old lamp works at all try putting it back to see if same issue--did you replace just the "bulb" in the housing or the whole cartridge?

If remove new lamp look at it and where it faces--usually a clear lens faces it and if some dirt on that..........

not sure which model you have but sounds like the blue polarizer has overheated over time. when you put the new lamp in I would think that the extra light you now have is highlighting the problem more plainly.
If this is the case then a new polarizer would be needed

Sony 60" LCD projection TV has yellow screen discoloration


It sounds like you have a bad Blue Polarizer in the light path. I'm sorry but that is something you will have to contact a service center for. It's not something you'll be able to do yourself, I'm sorry, but that's the best advice I can give you.

InFocus LP 850 Projector, yellow spot on screen


Hello,
Unfortunately the discoloration is caused by the extreme heat generated by the Lamp has burned the LCD optical polarization filter/elements.
The only solution for this is to replace the entire LCD optical assembly.

Sorry for the bad news, :(

Yellow Spot dead center on screen


Any color spot is never the lamp with this type of set.
the yellow spot is caused by the optic block (Engine). Very expensive to buy.
Little over $1000 plus labour with a qualified technician.
Sometimes technician may try to clean or repair inside but most likely won't succed.
good luck.

Try the new lamp as indicated by the blink codes. That may resolve the problem. If not, the problem is in the "light engine" portion of the set which should be covered under warranty.
Keep us posted.

Yellow spot in center of screen


I have recently developed the same yellow spot problem on my Sony KDF-E50A10  50" LCD television...a large yellow circular hue that takes up the bottom center of the picture and is especially noticeable against a white background.  It has been diagnosed as the optical block (light engine) and without an extended warranty Sony refuses to assist with the repair cost.  Repair was estimated at $1,100 plus tax and travel fees to my home.  So you see, it is not only a Hitachi problem.  You would think they could build something that would last more than two years considering the initial cost of over two grand for the TV !
