Samsung Repair Guide: Common Issues and Fixes

Brand Model Fault Detailed Problem Solution By

Image shaking and with scratchesScreen boardI placed a 33k resistor in parallel with rd 37 on the screen board. it was perfect. good luck!Eletrônica Cecé. Brumadinho MG
SAMSUNGLN40B530
Sound talking, making some clicks, popping only on the dtv antenna input, on hdmi everything okDirty board with a lot of solder flux.Complete cleaning of the board was carried out, as tsound was a lot of solder flux on the entire board, cleaning was done with isopropyl alcohol, cleaning and scraping of the ground points wsound the board was fixed to the chassis.CDS_DIAS

Sometimes it doesn't turn on or goes out intermittently, causing cracks in the solder of the tb801s transformerSolveSANTOMEL

Restarting in seconds straight never stopsThe wifi sign is short and just disconnect it and the TV returns to normal.Replace the plateIvan Passos

Knocks relay and flashes LEDsCheck 15v resistor rs802Check rs802 - smd 10r, close to ics801c. at the entrance tsound must be approx. 15v. After that it drops approx 0.3v. If not, check regulator qs801, if voltage is coming in, check zds803. pass: zenner-diode-regulator-resistor-jumperdsolucoes

The device just pulsed the VS and VA voltages and lowered them until they reached zero. while the LED on the signal board blinked.On the y-sus board, q5013, q5024 (both 500v vds and 50a mosfets) q5016 (igbt transistor of vce=330v and ic=20a) I also found the open 18Ω smd resistor r5831 at the power supply.Replace components.
