Hi,
Usually this happens when lamp becomes weak or near to end of its working life and start consuming more current to produce light that activates protection circuit to shut down lamp for moment then back On.
Lamp light will lit on tv front if lamp got broken or dead.
How old is this tv and did you replace its lamp in last 2-3 years? If lamp has not been replaced recently then change it. Please buy Sony original lamp for good picture in tv.
Lamp replacement procedure is easy and written in user manual.
Let me know if you have additional question.
Thanks.
