SAMSUNG LN40C530F1M
BN44-00340A 		Dead power supply Open 3.5a fuse fm801s causes 22nf/1kv capacitor c1831 shorted, after replacement tv turned on but without black light solution was to replace ub801 a ci 431 smd and photo pc803 Maxwell
SAMSUNG 50J5500
TV keeps blinking 2x in a 5x cycle TV came with standby protection First do the test: remove the flat cable from the power supply board that goes to the motherboard. the TV turned on the backlights. then remove the ps-on track from pin 6. the tv will open the image and backlight normally. defect: changing mosfet smd that goes close to the motherboard connector: q206 (p-channel) Karen
SAMSUNG UN40F6400
Flashes standby and hits the relay repeating the process... power supply arm the LEDs normally when isolated from the main. Mosfet smd channel n 035n40 screen printing qm854 shorted pcb power The MOSFET was replaced using compatible SMD D4185 taken from various scrap Samsung power supplys. resolved. Note: this TV goes into protection by hitting the relay due to different types of problems, it is good to evaluate it carefully! att,

Does not turn on, red light flashing, stand by flashing. C210 shorted and 9v regulator ic202 SERVITEC Quixadá Ce
SAMSUNG UN40EH5300
Dead power supply, dead tv Cp818 blown, icp801s (spc7011f), zdp801 (in front of ic icp801s (double smd diode)), fuse at input fp801s Replace of the mentioned components Claudio Jorge Eckert Junior
SAMSUNG UN65RU7100
Does not turn on or standby Capacitor cp818 toast and qp802 shorted Cleaning the board because the capacitor carbonized, changing the transistor, in my case I put two w20nm60 same rds on and voltage, but with higher current, and cp818, 221k for 2kv and 5a fuse the board started working again Mitzko eletrônica
SAMSUNG QN55Q7FNAG
Only standby, when pressing power it did nothing and turned to standby After analyzing the TV boards and finding nothing wrong, I decided to open the one conect for analysis and located a heating in the middle of the board. When measuring, I found a shorted capacitor next to IC207, I removed the c267 capacitor and measured it outside, finding a short. When turning on the TV without it, everything worked perfectly.

SAMSUNG UN55MU6400G
FA01 		Doesn't start Correction of the tip to use an alternative board from the 49mu6100. You also need to change the WiFi module and use it via remote control, as the mu6400 button is the only one André
SAMSUNG UN55MU6400G
FA01 		Doesn't start Main pci bn94-11955g very expensive and hard to find. I put one from 49mu6100 bn94-12439g and it worked perfectly. alternative for the original plate. Replacing the main PCI with the alternative André
SAMSUNG UN46FH5303G
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
