these are the repair tips for your tv
-check capacitors CS804, CS805, CS806, CM812, CM813 (all 1000uf/16v)
-Tip for appliances using the BN94-01206D signal PCB. (Relay clicks slightly faster with a NVM corruption problem. R1131 and R1132 (both 68R) have visible signs of overheating. 13V is measured at one side of these parallel-connected resistors (while relay is on) and 1.2V at the other side. 210R is measured across C1102 (1uf/16V), in line with the 2 resistors. if C1102 is removed then only 37R can be measured . Replace C1102 (with 25V type), R1131 and R1132 (both 68R) at the underside of the signal board, next to connector Cn1101.
-(Electrolytic capacitors in PSU have been replaced). NVM memory IC1803 (AT24C256) has corrupled software. then replace NVM memory IC1803 (AT24C256), then proceed as follows: switch of appliance via mains switch, then solder two long wires at PIN 5 and 6 of IC and short them at the other end, then start TV via main switch, wait maximum 1-2 seconds ( a click can be heard, backlight doesn't switch on), the remove the short circuit at the two wires. NOTE: it is important not to exceed the time limit(1-2 seconds), otherwise the procedure will have to be repeated, then access service mode (INFO, MENU, mute) . select 'tuner' line and set it to 'AUTO' . then select RESET line. the set should reset itself and upon start-up, it should start automatic search.
I hope this will help
