Question about Hitachi 42HDT52 42 in. Plasma HDTV

1 Answer

Can't change channels

Suddenly the TV won't change inputs or channels - either by using the original remote, or the buttons on the side (Hitachi 42hdt52). Volume and power buttons work fine.

    I am having the same problem. I have it at a repair shop now and they can not figure it out either.

I had exactly the same problem. I finally found the power button on the underside of the TV. It is well hidden and to find it, you need to run your fingers underneath the panel. Turn it off for a minute or so and turn it back on and then turn on the switch on the panel on the upper right side where the channel and volume buttons are. It works.

I have a Sharp TV model LC-32SB24U. I cannot access the menu screen because I lost the remote control. Is there another way I can change channels without a remote?


The Sharp LC-32SB24U has menu, input, volume up/down and channel up/down buttons on the top of the TV. When you access the Menu using the buttons on the TV, the Input button is the same as the Enter key. The volume up/down buttons map to the left and right arrows. The channel up/down buttons remain up and down. The Menu button is the closest to the power button (on the right). The volume buttons are the ones on the left.

Make sure that the input is set to TV to change channels. Then you need to program the available channels, access the Menu and navigate to Setup (left/right arrows). Press Input to enter this sub-menu. Then use the Up/Down arrows to select CH Setup. Press Input again to enter. Now you can set the channel source and let the TV scan for channels that have a strong enough OTA signal or are unencrypted cable channels. These are the top two options in the Channel Setup menu. The details are available in the manual which is available here: http://static.highspeedbackbone.net/pdf/Sharp_LC37SB24U_LC32SB24U_Manual.pdf . For OTA channels, you may need to check the signal strength under the Antenna Setup - Digital option in this Setup menu. OTA Digital signals will not be tuned in if the signal strength is low. It's an all-or-none tuning; amplifiers and external antennas may help. See tvfool.com for details of transmitters and the recommended antenna for your area. (Warning: damaged amplifiers can become filters and block the signal on some channels. Replace the amplifier if it is damaged.)

If you look to replace your original remote with a universal remote, you'll need one that was programmed more than 6 months after the TV was released. That may be 12/2005 based on the manual copyright date. Look for a remote that has a Menu and Input or Source button and check all of the codes to find one that matches all of the features on your original remote. Amazon has an OEM remote for the LC-32SB24U; remotes.com also has a replacement remote available that has been programmed for the TV. (On remotes.com, search for the LC32SB24U.)

I hope this helps.

Hello
It will be best for you to buy its original remote control. Universal remotes may also work with it, but some functions may not work properly. You can buy it from the Authorised Service Center for Toshiba at your town. Just give them the exact model number of you TV set [which can be noted at its back side]. They will give you the exact original one.

RCA RCR 311B model universal remote have setup codes for Toshiba. You may also try this remote. The codes are:
1047, 1071, 1103, 1105, 1108, 1159, 1163, 1178, 1188, 1190, 1191, 1196, 1211
I strongly advice you to buy its original one. OK.

Original remote lost. have universal remote. cannot program TV


On the right hand side of this television there are panel buttons. It appears that your son in law knocked the tv out of the correct input. Press the input button in order to cycle through the 5 inputs. Typically pressing the input button on the side panel of a television and pressing it again and again and again will make it change inputs. Universally the buttons on the tv panel function as follows: Channel up moves the cursor up. Channel down moves the cursor down. Volume + moves the cursor right. Volume - moves the cursor left.

Orion TVD2710. Lost remote, can't change signal input


I would suggest you try to find a universal remote that has an "input" or "source" button and program that one to your tv. By pressing the "source" or "input" button, it will change the input to the tv. I hope this helps! -Der Strom

Change from TV mode to AV mode for a Hitachi C28W4110SN


There should be buttons somewhere on the TV itself to switch input modes. Look around where the power button is located and see if there is a menu button you can access. Then use channel up/down and volume up/down to scroll thru modes to find input

Can't select front input without remote


I had the same problem, had a universal DirecTV remote that was able to control the volume/mute, power and channels (both TV and DirecTV), but the input button didn't work. There was no av/tv button on the front of the tv, and the autoregistration of channels didn't pickup the gamecube on the AV channel. What solved it was simply to press "00". I couldn't believe it, but it was that simple. Hope this helps you like it helped me, since the tv was not going to be of much use since we were using the RCA inputs, not the coax. Didn't want to try to conver the RCA to coax either.

You need the original remote controller to be able to switch input modes.Universal ones usually don't work. If you don't have the original remote and can't find it ever or if it is too expensive you can buy an rf modulator ( very cheap) and connect your dvd player, game console etc) to the modulator then connect the modulator to your antenna with a coax cable. This worked for me. It placed the connection to channel 4 and other cable channels are still working,

You can buy the RF Modulator from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=180299245670
