Hitachi 27 TV is connected to a satellite cable. Both are plugged into a power strip that was turned off while both were in the on position. When the power strip was turned on again the tv did not get satellite reception. A second tv remotely linked through the same satellite box works fine so it is not the DISH satellite system. While checking various functions of the tv I noticed it was not set on channel 3 to receive the satellite signal. Setting the tv to channel 3 I noticed most channels were in the delete mode including channel 3. Setting the tv to channel three does not fix the problem. Also after manually truning off tv the correct way , when restarting it it shows a cd/dvd disk moving across the screen. Any ideas Product is an Hitachi 27cx21b not what is shown as the product below.

Performing a power reset
1. Turn off the television.
2. Unplug the television power cord from the electrical outlet.
3. Let the television remain without power for 60 seconds.
4. Plug the power cord back into the electrical outlet.
NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
5. Turn on the television.
How to establish an HDMI connection between a TV and other device.
Follow the steps below if the HDMI® connection between your TV and other device is not working:
1. Make sure both the TV and other device are turned on.
2. While turned on, unplug the power cords for the TV and device from the electrical outlet.
3. Disconnect the HDMI cables from the TV and other product.
4. Wait 60 seconds.
5. While the HDMI cables are disconnected, plug the power cords back into the electrical outlet.
6. Turn on the TV.
7. Re-connect the HDMI cables.
8. Turn on the HDMI-connected product.

The TV should now detect the HDMI signal from the connected device and operate normally. If there is still a problem, disconnect the HDMI cable from both products and then reconnect it in the opposite direction. In some situations this has been reported to resolve connection issues.

Hopefully this post helps you! If does, please mark it "accept as solution"

could be alot of things but it comes on by hitting it makes me think either a bad relay or solder connection on the pcb board

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.

well most power strip are useless call ins. compay and hope you got cost replacement

Sounds like the power board has blowen and will either need replaced or repaired.

Check to make sure TV is on, there should be an indicating light when on. Check to make sure that coax cable or input cables are connected. Make sure that TV is on proper input for the device that you are trying to use i.e. DVD, Blu-ray, Gaming console, Cable or Satellite Box, etc.. Make sure that the input device is turned on.

If TV will not turn on it is likely that the TV set needs to be repaired, before calling your local TV repairman try unplugging the TV for a few minutes, then plug back in and try it again. you may also try plugging in something else to the outlet where TV is plugged in to make sure that the outlet is working or that if using a power strip that the switch is on, and circuit breaker is reset.

Yes.
1) Connect the cable from the Satellite to the input of the VCR
2) Connect the VCR Output to the TV (Either Coax or RCA).
3) Tune the VCR to Channel 60.
4) Enjoy your Satellite programing...

Good Luck....

While Bluray pluged into the TV change the resolution from AUTO to 720P then plug Bluray back to the receiver and see if it solve your problem.

Do you mean that the TV shuts off and the cable box also shuts off? Is the TV plugged into the back of the cable box? This sounds to me as if the cable box is defective and the TV is plugged into the cable box instead of the power strip. To prove whether or not the cable box is defective, plug the cable directly into the TV, plug the TV directly into the wall outlet and watch one of the lower channels. If the TV acts up and shuts off, have the TV serviced. If the TV plays fine, replace the cable box.
