leave the TV on...........unplug it with the power on. let it sit for 5 mins. unplug all audio/video rca jacks,and cable source. and first 3 screws un plug tv stand strap. Take the back off (6 more screws) Look for the little metal box at the end closest to you on the circuit board that plugs into the front buttons. On the back of the box there is 2 screws vertically from each other they should be covered with dust pretty bad. wipe the dust from around the screws. wouldnt hurt to clean it up a bit but dont get carried away just blow the dust off that you can with your mouth and wipe the dust off the base. The bottom screw should say picture. let all the dust settle,hell take a well deserved break! now plug The tv in again. re-attach cable. Turn it on and give it 5 mins to warm up. slowly turn the bottom (picture) screw to the right verrry slowly and you should see the picture come back. now turn it down slowly untill the picture drops again. bring it just back up again and give it just a little extra. but not too much as it will wear the crt faster. youll see............ now pull the cord out of the wall again. reassemble. plug in. watch for 1 min. now turn off again. while its off press on the remote ---channel button-----5-------volume down-----Power-- then after it comes on ----8--------enter. Hope this helped.
