Symptoms of TV shows the lamp in TV is about to fail / at end of working hours life and requires replacement.
It is normal with lamp in this TV as it has limited lifespan and goes out every few years, some times it popped and you get Lamp light on TV and some times exactly same symptoms appear.

Lamp replacement is easy and user level repair, written in TV user manual page, following link is to download user manual copy, if needed.

Please copy the link and paste in browser to view the lamp and its price.
There are counterfeit lamps available in less price all over internet that wont last longer, I would recommend to avoid such low price lamps.
