Question about Sharp 32U-F810 32" TV

Channel switches on it's own

Our TV switches back and forth from input 2 to a regular channel on it's own.  It does this intermittently.  It can behave for a month at a time and then it will start acting up.

This is probably a sticking button, similar IR signal from another remote control, or simply a short on the system board that holds the controls.  A simple cleaning might take care of this.

How do we scan/program in local tv channels. We bought an external antenna, but get no picture. Typically, there is a protocol for scanning channels into the set. Model is Sansui TVS2746B, and the set was...

Okay, does this tv have a built in DIGITAL tuner? Most tv's only have an analog tuner. You can tell the difference while you are changing the channels. If the channel indicates 2.1 or 2.2 and so forth, it is on a digital channel mode. If you change the channel and it indicated 2, 3, 4, etc. it is analog. If it has digital capability change the input until you see 2.1, 3.4 etc. If you cycle through all the inputs on the tv like, input 1 (TV) input 2(DVD) input 3(HDMI) and so forth and you never see the digital channel you most likely do not have a digital tuner. You will need to purchase a digital converter which will convert it to analog and you can watch it by placing you tv on analog channel 3 just like the old vcr's. Hope this helps and please don't forget to rate this solution.

I can't program my tv to regular antenna channels

You can program to regular (analog) antenna channels. To do so you must use the original remote which has a TV/DTV switch in the top right corner of the remote. Choose the appropriate mode for the type of channel you want to see or scan for. Here is a link to the owners manual and a picture of the remote swithc. The info on the signal switching is on pg.13.

The tv switches to Input while trying to watch Dish.

Likely a button on TV is sticking down or partially shorted.

TV freezes when switching to a digital channel

The problem your describing can be contributed to your cable box. Depending on your cable company there are times when the box has trouble translating the signal to the tv. You tv is operating normally. Suggest to the cable company to switch your box.

TV image goes off when VCR power turned on

The vcr is connected in between the antenna (or cable) and the tv, and when it turns on its tuner takes control of the signal. Either:
1) press the VCR/TV button on the VCR to let the signal go stright thru
2) Tune the VCR to the channel you want to watch and set the TV to the VCR's input.
3) If you use a coax cable connection to the TV, try switching the VCR to the other channel (3 or 4, switch in the back)
4) Change the TV connection to RCA cables on the A/V inputs.
Hope Ya Fix It!

Sharp tv changing channels

Well, the only thing that seems to be working so far is to plug AV cables into the "input 2" ports (on the front of TV). I plugged in my PS2, without turning it on. It has not switched at random since (about 30 minutes - it had been switching off and on for the past 2 hours). Anyone else have similar success?
