I have the same blue screen and tuner problem described in the previous posting. This TV is 4months out of warranty. I went through the trouble shooting as described in the previous posting.I would like to replace the tuner myself. I have some electronic experience. If I could get the part and a schematic I believe I could do it myself. The TV only cost $200.00 so it is cost prohibitive to get a repair shop to do the repair. Estimate of $130.00 by local shop.

Displays blue screen and shut down; denotes no signal input to TV. Check all the signal inputs, Ariel, AV or so. If all are found OK, the tuner to this TV is faulty. Contact any service technician.

Are you using a cable or sat box. If so then you are selecting channel using the tuner in the box and sending a constant signal to the TV eithir on one channel of the tv tuner or one of the other input of the tv. If this is the case I would suspect the box and not the tv because you say it is only on some channels.. If you are using the tuner in the tv with cable or antenna directly in I would say the main board that has the tuner on it needs replaced. Without a specific model number thats the best I can do. Hope this helps.
I am an installer for a nationwide big blue store. The inputs on the back of tv's are fairly fragile. In my opinion, if the tuner to tv interface is damaged, ("In the process the ASC tuner, or internal tuner, was pushed back into the TV and the technician said it couldn't be repaired.") it probably is not repairable. Or at least, not economically repairable. Cheaper to replace the whole tv.
On the up side, $850 is pretty cheap for a 47 inch flat screen.
Follow up on No DTV tuner after unplugging it a month for vacation. After I let it set plugged in for about 2-3 days it started working normally again and has been fine ever since. I hope this may help someone else. Genez 6-7-09
first off lets try pluggin in something else into that port to see if it will recognize that. if it does then we know it is not the laptop that is in question but the software or device mangaer properites.
Sharps are known for bad tuners and cold solder joints.If you tap on tuner and picture comes back there is cold joints in tuner, If not most likley bad tuner. if the audio is there with blue screen it is the tuner definitly.good luck
Does this happen when you play a dvd? if so your RED, GRENN, and BLUE lenses in the tv may be out of alingment. First try pulling the power on the tv (make sure the tv is turned off first) wait about 2 min. then plug it back in. If this stil continues, then what i said earlier may be the case and sorry to say unless you have a warranty you will be better off to buy a new tv. Now days it costs more to repair a tv than to buy a new one. And it could very well be the receiver
