Unplugged for 5 minutes. tightened connections
Id suspect a convergence circuit failure a model number is always important just like going to get a part for your car you need information so you can be assisted with correct information and parts .but il take a guess its a HD52W ?? ON THE DEFLECTION BOARD that's the board on the left side when the back of the set is off . id check connections on the fly back transformer and see if there are a couple cracked they need to be re-soldered . and its possible that a pico fuse is open there on the source . that will need to be replaced . also at the right side of that board are two chemical ribbons that come over from the main signal board there are connectors there if there white they need to be changed to a new part that is black that was a problem that often went unnoticed . the pico fuse sits to the right side of the fly back transformer there three little red squares its the middle on you will need to check with a meter on OHMS scale to determine if its open .
