Question about Hitachi 42HDT52 42 in. Plasma HDTV

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 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.

I have a Panasonic TH-42PX50u that suddenly is stuck on one channel and no volume control either. Same whether using remote or on TV. Only turns on and off no other control.


Try changing the input device to something you are sure, works such as a DVD player. Look for any loose contacts in RC jacks/sockets/Cable. Look for jammed buttons on remote and/or on control panel. Try removing the batteries from remote and operating from the control panel of TV. If these are ok, Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Tv won't switch to "tv"


Your T.V. is programmed to store the last input you've selected. You have to manually switch it back to your T.V. channel input after each time you switch it to HDMI or any other input even when you turn it off. The "Source" or "Input" button on your original T.V. remote will change this.

I lost my remote for hitachi CMP401XU and i dont know the remote # so let me know which remote i bye for it


any universal remote would work but hte hitachi remote for that model is expensive i suggest buying a logitec harmony universal remote for around 40 bucks from amazon. you plug it into you computer and just type your model number in it will install all the original options to this remote plus allow extra features such as activities where it can change the channel on your tv and turn your cable box on and let you change volume on your sound system without the hassle of having to use different remotes. and without having to hit different buttons i.e cable button to change channel and tv button for remote it will do it automatically

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.
Hope this helps

Powers on will not change channels or video inputs


Is your remote programmed properly? If it is a universal remote, try setting it to one of the different codes for your brand. Sometimes the power and mute buttons and things like that are the same for all different types of a brand, yet all of the channel and volume things are different. If it's the remote that came with the TV, then I would try to get a replacement, as it could be faulty. Hopefully this problem is with the remote, and not the TV. Find if this is the case by using the volume/channel buttons on the TV itself. If they work, then you can be reasurred you don't have to call the TV repairman, and you will probably be able to fix this problem yourself.
