The spot may be from debris inside the chamber of the TV box. A bug, dust speck, or other material can attach to the inside screen or on a color tube inside of the unit. Do not touch the inside of the Front Screen as it has a special coating and you could damage the screen permanently. Avoid washing with water or sprays that can enter the frame of the screen. Use a cloth with cleaner applied to it and wipe clean, then dry with a soft rag or paper towel.

From your description it sounds like the lamp bulbs needs to be replaced.You need one of these:http://www.amazon.com/Hitachi-50VS69-Watt-RPTV-Replacement/dp/B006C58MOINOTE: DO NOT TOUCH THE GLASS PART OF THIS BULB. The smudges from your fingers can show up on the image projected onto your screen and make things look blurry.Once you have the new bulb then turn off the TV and unplug it. On the back panel there is a rectangle on the left with a screw holding it on. Use a philips head screwdriver to loosen the screw then slide the rectangular panel to the left and pull it off. Inside will be the old lamp bulb. Use the screw driver again to remove the screw holding the lamp bulb in and pull the lamp bulb out (it may be hot). Insert the new bulb and then screw it back in. Place the panel back on and screw it back in as well. Make sure the screws are tight or the TV may not turn on. You can now plug the TV back in and turn it on. If done correctly this should resolve the issue.

First it is not a good idea to turn set off by removing power that way, I would suggest first if you have a box or and a receiver in line to remove power from all of them and let set for several minutes(I have no idea what units are hooked or if this has been tried so I mention it)Second is did you have the same issue or a different one before the lamp was replaced==this started after the lamp was replaced or not?Third is was the lamp a OEM type or after market one?I am trying to rule things out so bear with me.If none of the above helps I can only suggest it may be either the Lamp ballast or even dust build up in the set--fans intake air and exhaust it---it does not take much to slow a fan down if coated even with a fine layer---no matter how clean the home is dust will get pulled into the set.I have seen this in several sets ---I usually will take it outside and dust it with compressed air(I know its winter but it may look like a dust storm if you do it----we don't want that.)Just some thoughts and suggestions from a tech with over 35 years of fixing all kinds of sets from the tube ones to the current generations of Plasma sets.SD TECH

Almost all you can either get into the mode by use of the remote or remove front speaker grill and inspection plate behind it, there is a tiny blue push switch which will put you in the convergence adjustment mode, then various buttons on the remote do different things and save the adjustments.Of course if convergence will not adjust you have a bad chip and this model uses two so both get replaced in that case.

Yes, if the spots are round or teardrop it may be burnt picture tubes.Easy to confirm this by covering lens of tubes one at a time with set on and see which removes the blotches.What happened in a lot of these sets is the set arcs and burns a black dot dead center in one or all three of the screens of the picture tubes used--fatal case and permanent.

You have a defective optical engine. Replacement of the engine is necessary and the cost of parts is between $500 and 600 alone. Part number is UX26114 for earlier models and UX27714 for serial #V6i016788 and above.

i am not sure about this perticular model but i have found in other sets that the front buttons on the set might be causeing the problem. the switch may have become dirty or damaged. if i had it in the shop i would first look at these buttons

A green image is usually due to a lack of red or especially blue. the problem is becoming all too common with hitachi lcd projection sets. what happens is that one of the lenses in the optical block (or light engine) starts to burn or discolor due to overheating because of a blocked air filter causing poor air (cooling) circulation. Nothing can be done when the damage is too far gone except to replace the light engine-at acost that makes it not worth repair. if the damage is minimal than to reduce further damage the air filter should be replaced. Light engine needsto be removed in order to replace the air filter.

make sure the lamp cover is in good and the screw is snug just had mine open and only thing that it does is red light flash and nothing on screen......unplug power and try it then plug it back in about three or four minutes later.....hope that helps

Take the lamp out and examine it. Are there any blackened markes that look like arcing marks? If there are then the lamp may be faulty and that could be caused by the ballast but in my experience of working with Sany and Philips lamps, the ballast units generally fail without causing lamp problems.
I should go for a new lamp.
Hope that helps.

Most of these hitachi's have a lamp door on the back or behind the front panel (most).. pop off the front panel and open the little door, using a philips screwdriver and then you can pull out the lamp.
to get a new lamp, check out www.dlplampsource.com for a decent price and 1 year warranty

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!
