Sounds like the main system control memory IC to your TV is faulty. Just try a hard reset to this set, before change the IC. After the reset has been done, run an auto channel pre-set and see whether the set mesmerized all the channels it has been tuned in. If not, replace the IC, and re-tune it.

It sounds like you have taken the steps to isolate the problem to the TV. it seems to be a bad tuner on the Main board. The no signal displayed indicates the TV is otherwise okay. If you have a DVD player or other source you can connect, and you get a picture, then your TV has a bad tuner for sure.

It sounds that the digital system control memory IC at the digital tuner section is faulty. Try a reset to this set, and check first. If it do not help you, replace the IC. Contact any service technician.

Hello
I don't know the Brand and Model of your TV. Yet considering it as a common fault for all TVs and posts this solution.
Your TVs memory IC has damaged. Every TV, which has auto tuning function will have this IC in it, to whcih tuned programmes details are stored as digital signals. It is a very small IC, of 8 terminals can be located very near to the system contro IC inside your tVs citcuit board. Locate this IC and resolder it out, note its number and go for a b\new one. They are easly available, and not costs too much. Replacing it will solve your problem. OK.

Hello
Go through your TVs operation manual. and set it to auto tune. It will regain back all the channels cleared after the complete tuning process. Wait for to tune for all bands. Never interupt the process until search process ends and displays the first programme got by it on the screen. Ok.
