try unplugging and plugging back in 2 minutes later. go to menu and find channel selection. scroll down to where it says channel. then using volume up and down buttons. will add or erase channel. just play with it and you will see what im talking about. go to channel 4 and press volume up. this will save channel 4 in memory. if no work, try turn on video souce and do a auto program in menu. fixed. enjoy!
sounds like a heat dissipation problem, or was, I take my covers off and airdust my sets every 6mths when I do my computers Sharp televisions are extremely good sets, my mom and dads sharp 10 inch color tv with vacuum tubes worked for 40 years without a hitch. I would take yours in to see how much its going to be. be careful if you take the cover off , theres high voltage present even unplugged via the heavy single red or yellow wire going to the tube.
Yuor TV has an issue particularly in the power supply section with regards to the loose components. This issue can be best addressed by having your units' circuitry be resoldered before it could damage some parts.
