At sw on reverts to st/by with led flashing twice | Measure volts at collector q606 (located in the middle of the pcb towards the right edge), if it stays at 0v, then you need to replace or re-set the eeprom, if it goes high - then overcurrent protection is activated, suspect faulty lopt. after replacing the lopt, collector q606 should stay at 0v and the set should come on, however with some software versions, the error code 2 will remain in the memory and you need to clear it manually.to clear the error code from the eeprom you can replace it with a blank one, but it is much easier just to re-set it. while your error code 2 is still flashing, press on the remote control: [5], [-/--], [5], [9], [standby], [i], [5], [vol+], [tv]. the set will come on in the service mode with tt-- on the screen, press [menu] and write down all the settings for picture, geometry and sound. then press [menu] again to return to tt-- screen. enter 49 to clear the eeprom, and switch the mains off. now go back to the service mode (tt-- on the screen), enter 24 to set destination "uk", then press [menu] and enter all the settings what you have written down. the sequence [5], [-/--],[5],[9] sets the tv on program 59; the sequence [standby], [i], [5], [vol+], [tv] is used to enter the service mode. in order to execute the command tt49 (re-set eeprom), the tv must be on program 59. | ||
