I have a yellow spot dead center on my screen. Didn't realize it until my kids played "March of the Penguins" - the yellow spot stood out against the white snow. Any do it yourself remedies for this? If not, what should I expect from a professional repair visit?

Re: Yellow Spot dead center on screen
Most likely the yellow dot is due to a burn in the picture on the "green" lens. It's not removable because it's burned it, but you can try cleaning it because sometimes, dots are caused by dirt. The worst that can occur is that if the dot is permanant.
I have a 52" rear projuction hitachi tv. I had the same problem. The solution to my problem was something called a OPTICAL ENGINE. It was replaced yesterday and now my picture looks as new as the day we bought it. This part is not cheap. on the invoice it was 921.00 for them to repair my tv with this part. I hope this helps.

Sorry, but there is no cheap method of repair for this unless it is in warranty.
This TV will require replacement of the LCD Prism unit.
This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.
Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.
This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty.
the lcd panel for the blue is bad normally you would have to replace the engine but i know a place where you can get it rebuilted for a price cheaper than the engine go to

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.
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.
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 !
