    Vizio Tuner Cards DTV

    I'm looking to buy a replacement tuner board for a Vizio P50HDTV10A. I see that the Vizio 3646-0012-0190 Tuner Board 0171-1472-0355 which is for a different model looks identical but the flash device has a different label. Does anyone have experience with these as being interchangeable?

    I replaced a 3646-0012-0190 (GV46L LCD) with a 3850-0012-0187 (P50HDTV10A Plasma) with no ill effects.

      Thanks for that info Cliff.. I have 3 of the 187's that are not working. When I try to bring up the menu when the input is selecting DTV, the menu doesn't come up and the TV hangs... I sure would like to know what's causing it. All the voltage regulators are running fine on all three boards. Must be one of the ASIC's or the flash parts..
