Hello, I have a LG rear projection tv model number LG 52SZ8R-ZA that has recently stopped working at 100%. The screen appears alot duller as though the brightness has been turned right down. Is the problem...
Hello, You can get better prices for bulbs on the Internet. I went through this problem with my set.
Sometimes there is an upgrade in bulb Wattage on an individual basis by Model. What you may be having problems with is a system called a "Light Engine". This assembly has the power module and a spinning part called a "Light Wheel".
Your problem then can be from any of these devices. Your old bulb could have a dark spot (As normal light bulbs can develop), a weak power module, or a light wheel not spinning at the correct RPM for clarity.
You can take a chance and try a new bulb yourself or call for a Technician to give you either a "Convergence Set-up" or Evaluation and Repair estimate.
I learned about the insides of these TV's from the Front-Projectors and my own Rear-Projectors which had Warranty Recalls. So I have seen Messed-up and know what it looks like and somewhat about the causes and cures.
If you are getting a Convergence service, you may want to get the Estimate, then install a new bulb through the Internet, and then get it all set up fresh with the new bulb.
