Kits are available but price is not real cheap---basically you have to unbolt chassis and release some cables inside to get enough room to pull chassis back and put up so bottom faces rear of set.
In this model both chips are near the middle of the set inside--unsolder all 18 pins on each and the 4 pins that hold each heat sink in---you remove the sink with chip still attached--clean the white grease off, apply new and replace both chips.
Works best if put front chip WITH THE HEAT SINK ATTACHED back in first and repeat with rear sink---it means when you install you have to get 18 pins plus the four pins for the sink installed in one shot.
May not be a task for a first time person.

If it is a minor misalignment it can be corrected from the user menu or the service menu. If it is a major misalignment because of faulty components, typically it will cost at least $300. Don't be surprised if you get a quote of $600 or more.
If you are handy and can solder, you can do it yourself for about $50.
