Does not turn on, no standby | Fuse fp801s open, transistor qm801cs shorted and ci pwm 3s111 defective, replace them all. | NiloTech | |
| SAMSUNG |
HT-F505/ZD
|
Device turning off (fan ng message on panel) | Oxidized cooler connector, replacing it solved the problem | juan | |
| SAMSUNG |
UN40ES6500
|
When switching on, the relay hits and nothing else, without 13v and 140v power supply voltages. LEDs, with low pulses at these voltage points. | In this case the problem was 01 of the 4 Q9401 MOSFETs shorted, just change it and the problem was solved. | ALBERI F S | |
