    Hi cooltek,

    Had her on Live Session, the Sanyo Visio is hooked to a cable receiver box via Y, Pb, Pr and Audio L/R. The only thing that works on the remote is POWER. INPUT button doesn't do anything as well as all other buttons hence can't select COMPONENT3.

    The user was asked to do an overnight reset and will work from there again.

    Hi again jtrent2,

    Appreciate the update.

    The reset is supposed to have restored everything to the factory defaults. Having done so and problem persist, it is possible that:
    1. the remote and/or the INFRARED receiver is defective. One way to determine which is which is by trying another remote. Alternately, you can check if the remote is functioning is by watching the LCD display of a DigiCam or mobile phone with cam while pressing on the different button of the remote while it is pointed towards the lens of the cam;
    2. another possibility is that the unit has an EPROM corruption. If so, it needs to be replaced. On certain instances, it could be the enitre logic board of the unit that has to be replaced.

    Option 1 would be relatively ease to perform while option 2 would require the services of a qualified professional.

    Incidentally, pls try checking if your cable receiver box has a single yellow video out, you can try hooking it to one of the TV's VIDEO INputs and try that connection instead of the Y, Pb and Pr.

    Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

    Good luck and kind regards.

    Thank you for using FixYa.

Jtrent2- O.k you say your t.v has nothing hooked to it at all, what do normally have hooked to it. Do you normally run coax cable,or rca input. The tv is looking for your source ,hook up your regular source, and see what you get. The tv needs to see a source,of some kind. Try hooking a vcr to the cable connector on the back, play a tape and scan your channels.The tv should pick up the vcr as channel 3 or 4 and lock in. Try this and let me know,I can help you. cooltek Mar,3/08

I can't figure out how to program cable box. The cable is hooked up to the TV, but I can't find out how to get channels. Is there a certain menu or imput?

Are you getting any picture at all? check your tv's input button on the remote if your cable box is hooked up with hdmi select hdmi, if it is component video cable select component video, and if it uses a coaxial cable it should be something along the lines of tv. Push the input button on the remote to switch between the different modes

Game button on remote - I cannot get tv back to cable - it is on black screen and show "cable" on lower right of screen

Is there a input key on the tv itself that you can try to go through the different video inputs or try pressing the channels up or down keys on the tv set. check the owners manual under set up to restart the channel program.

Big Blur when i turn the tv on


First of all please check the following things:

Press the TV button. Make sure the TV is plugged in. Check the wall receptacle (or extension cord) to make sure it is “live” by plugging in something else. Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the remote control solutions. The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Front Panel Block in the Parental Control menu and press OK to uncheck the box. The TV might be performing a periodic diagnostic check. Wait for a few minutes for the TV to turn on.

If still the problem persists then check the following:

Maybe the cable/air function is set to the wrong position. The channel might be blank — change channels. If you’re watching your VCR and it’s connected with coaxial cable to the CABLE/ANTENNA jack, tune the TV to channel 3 or 4 (whichever channel is selected on the 3/4 switch on the back of your VCR). Also check to make sure the TV/VCR button on the VCR is in the correct mode (press the TV/VCR button on your VCR). Check antenna connections. Make sure all of the cables are firmly connected to the jacks. Try adjusting sharpness function to improve weak signals. Closed-captioning might be on. Check Closed Caption in the Setup menu.

Please do rate this solution as FixYa and revert for further assistance.

Do we have to manually set the pix set key for every station/show we watch? We loose scrolling writing at the top and bottom of the screen on my dad's new 32" lcd tv bought at Wal-mart. When we set...

Thanks for the offer but we cannot afford to pay additional money for something the Factory support service Should provide.

From what we have heard through the Verizon installer, our SANYO LCD TV probably does NOT have a Automatic picture adjust system. That would most likely be the reason for the maunual button on the remote control. The troublle is that with the FIOS service, you do NOT use the TV's remote control. That leaves to switching back and forth between two different remotes wiich can be vary confusing for someone that is not 88 years old.

It is bad enough that you have to remember which channels you have to go to to receive HD programming signals. If I were making a TV set, and or running a TV network/ cable service, I would transmit both HD and regular signals on the same channel number and let the TV and or the decoder box figure out if my set could display High Definition. Isn't that what we spend lots of money buying equipment and paying each month for service?

If anyone out there knows if the SANYO 32 inch LCD TV sold at Wal-Mart automatically adjust to the picute format, (PIX 1-4) we sure ould like to hear from you.

Without the code, you must get an original remote and press the "QV" and the "9" buttons together to unlock the TV.

Can't get any channels on the air.\

If the tuner is the problem then it is a very bad problem as the tuner is part of the DM module and that is very expensive. When you say you have to manually key in the channels, do they work then? If so the problem is not the tuner. If your only problem is that you cannot go from one channel to the other by using the channel up and down button on the remote, then you have most likely just lost the programming on the tv. Go into menu and set up and find the auto channel programming and run auto program to correct the problem.
