The 6 blinks are a diagnostic code to indicate the problem circuit. I'm on the road at the moment, but will look up the code when I get to the shop. In the mean time, a few questions:

1) Does this occur all the time or just after or before a warmup period?
2) Have you noticed that this is occurring more frequently lately or did this just start?

Thanks,
Dan

Standby LED blinking 6 or 7 times and TV won't turn on

That is an error code that tells the tech where the problem lies. It is probably somewhere in the power supply stage. Your best bet is to take it to a TV repair shoppe and let them deal with it. They have all the documentation in order to repair the unit, and they can tell you what the problem is before they work on it.

The system has found issues with your TV.. The only solution is to call in service. Tell them the 6 blinks.. it is a code for diagnostics. Sorry.. the logic portion of the TV is experiencing some kind of breakdown. The only suggestion that I can offer is to hard reset your TV to factory settings.. other than that you are in duck soup..

Sorry...
