Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

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 moved roku from one tv to the other I see the light on but different inputs still show no signal


Make sure the Roku is on the same input that is selected. With that setup properly, unplug the Roku power for 30 seconds and then plug it in, then it should go through it's setup sequence.

Why does my tv show no signal


It likely has a weak tuner, made that way, not a product fault and will work with catv, devices and boosted signals. Other than that, check inputs on setup menu and see if there's an option to switch from cable to aerial as well as settings for a default channel setup that switches between clear signal and a set top box for scrambled channels.

ERROR MESSAGE NO SIGNAL INPUT


What is your TV signal source? Press the Input button on the remote and try another input. (Make sure a DVD player or set-top box is on.) If you are on the TV input, try a different channel. Next make sure that your cables are securely connected to the TV and devices. Replace with new cables to test them. If you use an OTA antenna with a splitter, try a direct connection. (Similarly, if you have an amplifier on the signal, try a connection without the amplifier.)

For OTA or direct cable connections, try accessing the Channel Setup menu and rescanning for channels.

I hope this helps.

(I get some weak channels that give No Signal messages when the transmitter has a problem or the weather is bad. I've also had a signal splitter/amplifier fail and block specific channels by becoming a filter. The direct connection identified the amplifier problem.)

Recieving no signal error


Have you checked the wiring and changed the input on the LCD to the input you are using? If you are in input 1 then the LCD must be on input 1 to receive signal. Current tvs have several inputs and must be changed on the setup menu.

HDMI signal from DVD can not be down converted to analog component signal.
Connect your new DVD to a component input 1..4. Make sure that component input assigned to desired input (dvd/vcr/sat/) (setup - input setup - input - component assign - component x etc). Connect coax output of DVD to coax x input of the receiver and assign it (setup- input setup - "input" - digital assign ..). Probably you need to setup DVD output resolution to 720i or 720p in dvd setup menu.

This is likely a problem with the receiver not the projector. If the setup screen from the receiver is displayed through the projector, then the projector is functional. If the actual signal is not displayed, then the receiver is not sending the signal. The setup screen is generated inside the receiver and is injected later in the video path than the input signal. Try a direct connect from the signal source (other side of the receiver) to the projector. Again, if that works, then the problem is the receiver.
