Question about Panasonic PT-40LC12 40" Rear Projection HDTV
Can you please help? Should I try a repair shop?
Usually indicates a bad or defective bulb. If new, it was manufactured defective. If used, it is usually due to excessive heat.
The ballast used to ignite the bulb could also be weak, but usually it turns out to be the bulb.
There is a method to increase the bulb's internal fan speed to aid in additional cooling and prevent overheating, but will also allow more dust to be drawn into the TV if the air filter is not sealed tight.
