F- 61 keeps comming up

Was having similar issue. Unplugged for about 15 minutes and plugged back in and worked for a couple days. Then it was dead again, unplugged again and working again. Hope this keeps working.

i had the exact same problem on my samsung 65" hdtv slp rear projection tv. i called a couple of places to get a quote and they all told me one of the lights burnt out. i got frustrated and left it on for 5 days and now the green colour is gone and its perfect again.
i think it was either very cold or i had let moisture get in to the circuit boards.
i hope this also works for you.

Unplug all phones and start plugging them in one at a time, starting with Jack 01 (either ext 101 or 21).

You probably have a bad phone or cable. When you get to it, the system will start shutting down again. The phone where the HOLD and SPRK button don't work might be the one causing the problem. Look for sticky stuff keeping the buttons from working (Coca cola?).

The tv projection Lamp inside tv now like 1 1/2 or 2 years already?Tv on and in used every day 4 or 5 hours every day?Yes,this problems,the tv projection Lamp live are ending.Replacement of the tv projection Lamp,tv will work again.

Error 61 is an over load in the audio output circuit of the unit. This is not a consumer repair. IT will need t be checked by a authorized panasonic service center.

I have the same thing. Just started blinking 10 times. Pretty much had to unplug the unit over night. Could never turn it off and then turn it on again.
This worked for about a week. This morning, tried to turn it on after being unplugged. Still blinks.
Called Panasonic. they attempted a couple solutions, nothing. Suggested authorized repair shop.

i don live in india....sorry mate

You're best bet is to get in contact with Panasonic to find out whether there is someone close to you that will have it. All Panasonic dealers are licensed through Panasonic so they will have all the information as to where you will be able to get what you need. I have never had a problem getting what I need when I contact Panasonic directly. Good luck

Hey! I have the same problem as you. But! this would happen only when I got a power outage. Unplug the TV for a couple of minutesand all was fine. For the last 5 day I have no TV. I have tried everything. All the out on the TV and I still get unusable signal. My rep told me to unplug for 24 Hours. Still didn't work. My menu option work as well and every time I put the TV on, off or if I change the input sound will come on for 2 seconde and stop. If I find the salution I will let you know. Gilles Ottawa
