Spot in center of screen, if the color pictureis black the spot is blue, if the picture is white the spot is yellow.

Spots in screen is commonly caused by defective LCD on the optical assembly. LCD replacement is very difficult. I suggest to contact the nearest service center at your area.

Picture issue

No,sad to say it is the end of your TV. Your Light engine"optic block"is bad. Caused by too mich heat.
Not cleaning the vents in the tv,smoking in the house can clog the cooling vents and internal filters.Causing poor air flow for cooling. The spots are from burnt polorised film on the LCD panels.The cost for the new light engine is about $600 + a costly core price. Encompass is down for the moment to get an exact price. But it is high. Time to get a new Flat Screen.And BUY THE WARENTY.!!! They all still have bugs in them. Costly to repair. I do the work for the warenty company for central FL. I repair 9-12 a day.One service call is more than the warenty. Light engine would have been covered. Sorry for the bad news. I have 3 of the 50" and 2 of the 42" in the shop for the same. Sony is the worst for this. Panasonic...
never a problem. Just a lamp once in a while.But the Samsung LCD/ LCD/led backlight is the best for the money.

Couloured spots on screen

sounds like you have colour impurity problems caused by a magnetic feild being near the Screen. Fist check for any new magnetic feilds nearby. If there have been no new changes, it may also be a faulty PTC device that automatically degausses the tube. When they fail, you will get problems with impurities by way of coloured spots on the screen.
Try disconnecting the set off at the wall for 30 mins, this will initiates the auto degauss process. If all is ok, the spots will be gone. If not, you will need to have someone handy with a soldering iron that is also familiar with TV repair to replace the PTC for you.

Please rate this solution. Happy to answer any other questions you may have. Cheers.

Dark yellow halo on screen

I believe you have a optical Engine causing the problem. Due to the cost, I would call Hitachi to see if they could help with repairs.
