I had the same problem with a old Sony TV.
To find out if the problem is temporary
- Turn off the television.
IMPORTANT: For
a projection television that uses an internal lamp, wait 5 minutes
after turning off the television to allow the lamp to cool before
continuing with the following steps.
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet.
NOTE: If
the television is plugged into a power strip or surge protector, remove
it from the power strip or surge protector and plug it directly into
the wall outlet. If the issue is resolved, the problem is with the
power strip or surge protector and not the television.
5. Turn on the television.
If the light is still flashing the tv has stop working and you will need to buy a new one.
