I have a 36" TV with cable attached. I recently moved it out to paint in back of it. All of a sudden the TV will just go out (snowy screen) as if the cable is out or was un-attached. I have noticed that banging on the ground, on the tv, or on the tv stand puts it picture (cable) back on, or off. I checked all the cable wires and they are all good and secure. I attached a direct cable from the wall into the tv to make sure it was not a problem with a cable. I determined that it is something in the tv itself, and I have no idea what to do. Is this something I can fix, as opposed to having a tech ($$$) come out to fix it, or is my tv junk??

ur AC fuse might be burn out or SMPS (power supply unit) might be damage. to check the first case, open the cabinet and locate for the fuse following the AC cable. if it burns out change it else take it to a authorized service man.
no rocket science here - my son fiddled with the cable cord attachment, until presto, the screen became sharp. Then we moved away as fast as possible, lest we shifted it and it put us back at square one.!!
You have the TV connected to the cable box with an HDMI cable, I'll bet. The problem is with the cable box. If you unplug the cable box and plug it back it it will reboot and proabably work. You should connect the cable box to the TV using component cables and you won't have this problem again.
I uncovered the problem. The "analog tuner" seems to have gone bad. The part is $25 -$36. The set can still be used however. I just removed the coaxial cable from ANT 1 in the back of the TV (this is what I believe has become defective)which was going to a VCR. I then just used composite cables(red,white,yellow)to bring the signal directly to the TV from the cable box, rather than the VCR. All works however, will replace the defective part.
your problem is intermittent but from your complain it seems that your IF video circuit which is vry technical have your set checked by a technician.to resolve your problem the job will cost about $90.00
