Sony | BE-3D KV28WS2U | buzzing on sound, IC260 gets hot | resolder earth pin on plug CN303 | ||
Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | LOPTx can be cause, confirmed by measuring volts coll Q606 in prot cct. If it rises to 11v LOPTx faulty (should be 0v) - then enter serv mode & disable prot (see other entry). | ||
Sony | BE3D KV28WS2U | St/by only LED flashes error code 2 | Instead of replacing the EEPROM try the following - Whilst LED is flashing enter serv mode (St/by, I, 5, vol+ & TV). This disables prot & set comes on with "TT--" . Press "0, 8" on R/C which will clear error buffer. | ||
