SAMSUNG T27B350LB
TV doesn't turn on, just blinks on standby. voltage ( ps_on ) missing. Check q202 is r206 on main board. in my case it was r202. replace with a 10k one Júlio/ Eletrônica JM
LG 50PB650B
Doesn't start Capacitor c671 shorted and transistor q508 shorted Replace them and go for the hug... Lucas Venzke
SEMP LC4246FDA
When plugging the TV into the socket, the stand by only blinks weakly and does not stay on. The cause of the defect is the ceramic smd capacitor c801 either partially or completely shorted. Eletrônica Dois Irmãos
SAMSUNG UN40EH6030
Stuck in standby Transistor qq852 is broken, it is an n-channel MOSFET Remove the wire from the connector corresponding to the p-on, the TV will turn on normally, then just replace the transisot qq852 on the power supply next to the connector, it is smd and is connected to the photo coupler Ariel Santos
CCE HPS-21AVP (HPS-2118)
H-2197A 		Does not turn on c805 stays charged Bad pwm observes the fr804 if it is open Replace ci pwm under the board and fr 804 Rogério TV
SEMP TV2134 C SL
SK11 		Turns on and off before turning off the sound was missing so I thought it wasn't the q606 C 613 next to the str at first I thought it was q606 Swap c613 carbonized Rogério TV

LG 42LB9RTA
LP7BB 		TV freezes functions, restarts, image flashes. Defect in the main PCI, check 3v3 IC1000 regulator. in my case it was high, outputting 4v instead of 3v3. rafaelmoraes99
AOC LC42D1320
Red LED on, when pressing the power button it turns blue for a few seconds and turns red again Voltage of 3.3 volts changed - check voltage at u702 and u705 Replace both, even if one of them is measuring fine. You can use az1085 which is much easier to find in scrap metal, they are available on LG boards and are more reliable than ams1084 Ruberval Rossi
RCF ART-415
Cutting the audio (bass) after a few minutes Leak in the 10uf capacitor connected to pin 2 of the irs20955s. 10μF x 50v multilayer smd capacitor. As a precaution, switch between the two channels. VanderBR

Frozen strip of image at the top of the screen Tired capacitors Replacing the smd capacitors on the main board Claudio
SAMSUNG PL43F4000AG
No image TV came from another service, they had already replaced c5078, q5000, d5057, and q5014 but tsound was no image, checking the circuit I found an omic value of 30r between the base terminal and emitter, changing the ci u5022 returned the value of 10k and the TV gave an image. IRIS TECCENTER
SONY SH2000
Entering protect Check pins 5 of each output driver by oscillating, they should drop to -5v and ramp up to +5v, in my case the voltage dropped to -5 and on the rising ramp, it reached 3v, dropped to 0, rose from new about 4 or 5 times and the protection worked. Replace the ci driver of the channel in question. Davi.sls
SEMP LED LE3278I(A)
Lower the LED voltage correctly. High LED voltage. To lower the voltage on the LEDs, you must replace the value from rp71 120k to 330k, on the line (iset) of pin 10 of the tps61196 evando viana
