My Daytek LCD TV has audio but no picture,keeps asking for auto tunning but no results after it's done.There is picture when TV doubles for my PC monitor.


Hi, Sounds to me like you are almost assuredly encountering a no signal problem. This would account for the auto tuning not doing anything. I would suggest a newer antenna. Local department stores carry a variety of " DIGITAL T.V. " antennas. And as far as the no audio part I have actually "seen " that problem on my own t.v. ( a portable ). When the tuner does manage to grab a signal if it becomes too weak the picture may freeze or go all diagonal or just disappear altogether leaving just the sound. I hope this helps and thanks for choosing FixYa, Good luck ,Prodzilla

Could be losing settings if it is an older tv when unpluged other wise are you letting it finish the auto scan, if so then the tuner is failing.

Poor tv reception on my new lcd screen


Hi, sounds like the antenna. Maybe get an Aerial company to check it out for you as you might not be picking up a strong enough signal.

Auto tuning


this problem is in system control section.

mostly it is due to AFT & Tunning circuit.

you will have to check voltage on that circuit.

also you can check loose contact in that ckt & near tuner also.

if you are aware of tv technology & all possible insfruments & schematic you can do it .

remember there is a high voltage in tv.

good luck.
