My KV-34HS420 won't come on and the Standby light


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...

G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

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.
