I have a Samsung 42

There is no color wheel or lamp in a plasma TV.


The problem is most likely the lower buffer " E ". It controls the right side of the screen. Worse case, it could be the Logic Board. A Service Manual for you TV will have the part number for replacement. The manual will also give you procedures on how to replace the part yourself. The service Manual for your TV can be found over the internet for less than $20. This is the best do it yourself manual you need for repairs on your TV. :)

You may have to change the DMD (Digital Micromirror Device). Also you may have to change the color wheel and lamp; the DMD will cost you around $200-$300. The color wheel and lamp will together cost you another $300.
This type of tv repair may be very expensive especially if you have to pay a technician to perform the repair for you.
It's at that point that you may decide to invest in a new unit.
