Question about Sharp 32U-F810 32" TV
My tv just started doing this. the channel changes to "input 2" auto matically then back to the previous channel and back and forth
We had the exact same thing happening with our same TV. We tried many things to fix it ourselves, but nothing worked. We finally broke down and took it to a repair shop. They were able to fix it within 24 hours and for $75. It has something to do with a short behind the input jacks on the front of the televsion. Hope that helps

press and hold the POWER button
on the TV control panel for 5 or more seconds to reset the TV.
Then connect the TV tt any source like outdoor areiel or cable box etc, select the appropriate input, and retune the TV. First of all, connect it to an external antenna, and set it to autotune.
• You must configure the ANT/CABLE input source before
programming channels (-left-hand column).
• If the ANT/CABLE input signal type is set to Cable, the
automatic channel programming process erases channels
that were previously programmed into the TV's memory.
• If the ANT/CABLE input signal type is set to Antenna, the
automatic channel programming process adds newly found
channels to the existing set of programmed channels (and
does NOT erase channels that were previously
programmed into the TV's memory.) To remove an Antenna
source channel from the memory, you must manually delete
• To tune the TV to a channel not programmed in the channel
memory, you must use the Channel Number buttons on the
• Programming channels when the ANT/CABLE input is
configured for Cable will take substantially longer than when
the antenna input is configured for Antenna. This is normal;
however, once channel programming is finished, you should
not have to repeat the programming process again unless
your Cable TV service lineup changes significantly.
Find out the received channels are clear or not. If they are clear, your TV is perfect, and the input device you connects ot the TV is faulty. OK.
