The main system control memory IC is faulty. Contact any service technician to replace it.
Before doing anything, try a reset first. In most cases, it might help you. There are two types of reset to TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight; will be better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/
Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.

    Even the Nobel company could not solve the problem. They repaired many times this model 21t27nf with the same fault and it’s become faulty again within two days

SOURCE: problem with tuning digital channel

I would believe from what you said, you have solved your problem. You will need a UHF antenna to receive the signal. Walmart or Radio Shack has a great amplified antenna that will work for you.

SOURCE: can not tune the tv

My dear friend. A TV is a TV and TV's are many and varied. If you stated the model and what it exactly does, maybe I or other people could help you instantly. But since you have said little in relation to TV tuning, then expect a few guys to help you. But allow me to give you a hint that applies to almost all flat panel TV's, ok? Right. On every TV there is a MENU that gives you many options. First you need to press a button on the remote that displays component connection channels and TVincoming signal type. Since I don't know what brand of flat panel TV you have, I can only ask you to find and press the button on the remote that displays on TV screen the following component channels, that is DVT, AVT, Component 1, Component 2, HDTV1, HDTV 2, HDTV 3 and so on. Apart from DTV and ATV, from Component 1 to HDTV 3, these additional channels are for DVD players that also have HDTV outputs and BlueRay players and or Audio devices. If yout TV hasn't got as many channel input, then ignore this part. To tune your TV you have to first press the butoon on the remote to activate the onscreen channel as above, then scroll on DTV or ATV and, depending on whether you have Digital TV in your country or the standard high resolution Analog TV. Lets say you have Digital NTSC format TV system, select it and then press ENTER on your remote. In the menu you find and click SCAN. Depending on where you are, the TV will begin scanning all frequencies in your territory and possible interstates if the modulator is powerful enough to pick up weak signals. Most TV's have an inbuilt set-top box that boost the signal to give you a crystal clear pic. Now, after pressing SCAN, the TV reaches a signal with a clear pic, all you have to do is recognise the channel that comes in view. The instructions on how to save that channel are on screen and then you can configure it as, say channel 4, if the channel that appeared is channel 4, if not, try and recognise what channel had appeared and then configure it with a number, so when you press that number on the remote it will be the same channel you had stored in the TV memory. After you have done this, press scan again and it will scan to the next channel. Once the scanning recognises another clear signal and it is as clear as a baby's face, you have recognised the new channel. Try, find out what channel it is by looking at the screen, there is usually a visible TV station name or number embossed on the lower corner of the screen, once you know what station that is or what channel number it is, configure that number and press ENTER (save) button. Do the same with the remaining channels. Later I will tell you how to skip unwanted blank channels that usually have no signals but snow and lines, or have faint signals that can only be boosted with a TV booster available from reputable TV retailers, or install a bigger more powerful antenna.

Reagards.
Mike

AUTO TUNING WONT RUN


Check and replace its main system control memory IC. If this IC is faulty, auto tuning will not work, or, the TV will store any received channels. If the TV do not tune into channels too, the AGC voltage to its tuner, and tuner itself should be checked.

New LG 32LD350 - Allowed TV to auto-program channels, and for some reason, it skipped past channel 4 during the tuning process. When I select channel 4 in the tuning options, it comes up as no signal. On...


When you are auto tuning the system will not store a channel which is week by its standard ( at least 60% signal strength ) This done to avoid grainy picture and hissy sound.
You can go into manual tuning and store it.

Vason 10.4 inch portable tv tuning problem


I returned my original TV/DVD to the suppliers who then sent me a new one.
I experienced exactly the same tuning problem with the new TV.
The only way I could tune it, was by using the fine tune facility to find and store the missing stations. This took a lot of time and continuous button pushing, so patience is essential.
Once found and stored, the previously missing channels are perfect.
It would appear that the DVD player doesn't like DVD- recordings from my home recorder. If they are re-coded they work.
Anything recorded on DVD+ is fine.
In my opinion this is a good unit let down by a couple of niggling faults.
