Unit getting progressively worse. Was intermittant now happens quite often. Comes on, then either a few seconds or several minutes later will shut off. Must reset main on/off switch on the TV to make come back on. Remote will not turn it on when this happens. Any source for a schematic or tip on problem would help. Thanks
With a Pioneer of this age, inspect all the solder joints on the ps/deflection board and resolder the bad ones. there will be many. Also check the joints on the convergence panel under the front grille. More than likely just a bad solder joint, however the condition you indicate is the proper operation of the powerdown/protection circuit.
When the set shuts off is there anything at all unusual about the picture?
Jammy
Nothing unusual, can hear the switchs click. sometimes after hours of use.
joints will be checked, THX.
