replace open fuse IC33 on PCB BOARD.
The fuse is about 2" behind the tuner. You will have to jump in a new pico
fuse.

Hi Bill
Thanks for the prompt reply
On the circuit board about 2 inches to the rear of the
tuner I see a small device with a F on it..Is this the pico
fuse and what is it's current rating.

Alvin, Replace the 500Ma with a 750 or 800 Ma. The rca p/n for the 750 ma is 275819. I use an ICPN20 which is 800ma.

Hello, I am in Calgary, Canada and have the same issues with my TV. Can you tell me if http://www.digikey.com/ has the part you are talking about so that I can fix my unit or let me know another place that I might try?

Thanks guys,

Al
