HOW TO GET TO AND REPLACE THE COLER WHEEL IN MODEL NUMBER Z52SZ80

What makes you think the color wheel is bad!?... It would require removing the light engine from the rear!.... Geo

If the color wheel is bad and set is hooked up correctly the tv will have will display missing colors as the color wheel is what gives the displayed picture its proper colors

yes a broken color wheel can prevent a set from powering up but a broken lamp could also shatter and have pieces near the color wheel.

If the ballast is truly bad purchase another and replace it--they are not meant to be "repaired".

It can also if damaged/bad damage the Lamp it is directly connected to.

Google the model number of the set with "Ballast" to locate a replacement part and cost.

If the buzzing noise sounds like a fork in the microwave, it's time for a new lamp. If it sounds like a squealing noise, it's either a fan or the color wheel. Color wheels are not easy to replace, so I recommend hiring a Service Tech.
