Sanyo TV DS31590
Came in dead-power surge.
Found H.O.T. shorted-replaced with factory original-blew out.
Found B+ high going to H.O.T.
Power supply replaced D612(open)Q605(shorted)Q695,IC681,IC801.
Installed new H.O.T. load tested(TVA92) applied power.
Now I get 80V going to H.O.T. Power supply seems to cycle like its trying-no
squealing-just won't go.
Pulled T801 tested on ringer OK.
Any ideas?
TIA
