SAMSUNG LN26B450C4M
It doesn't turn on, the LED lights up, keeps blinking and it takes a long time for it to work. This defect is misleading, because as we know, if we remove the cable that comes from the main board to the power supply and connect it to the power supply, the power supply, if it is good, allows the lamps to turn on, and this happened, so I suspected the main board, but the power supply persisted. I found the capa cm852 with low capacitance, 1200uf/10v, it was 600uf Cm852 sold out. Cm852 replace MIGUELTV
SAMSUNG UN32J4290
Does not turn on, completely inoperative, external power supply with 19 volts normal. In this case, heating was observed on the plate in the upper right corner. Short in smd ceramic capacitor c17 next to the ic206 regulator, just replace it and the TV worked normally. ToniTec

SAMSUNG UN32C4000 BN44-00349
Turns on with sound. no images The cm806 capacitor had a voltage of less than 8 volts and was oscillating. the transistor qm 801 was shorted and the qm801 (q0765r) without pwm, I just had to change them and the voltage in dm871 appeared and in dm874 oscillating I replaced the cm872 capacitor and everything went back to normal EPINFOR.COM

SAMSUNG UN32EH5300G BN91-09278E
Totally dead tv The power supply board was defective as I mentioned in another tip. After I lifted the power supply board, I found that the main board had a short in the a5v. It was the 3.3v regulator that burned out because of the shorted micom. Buy the engraved micom (for your TV model) which is already sold with the voltage regulator. Mercadolivre has these kits for sale. 2000

SAMSUNG CL29Z43MQ
Turns on and off in 5 seconds You have to be quick to enter service mode, TV on standby, press mute182 and power on the control, TV will turn on, you go to the first option option, item 10 v- save and turn it off. DJ PITUKA

SAMSUNG PN51H4500AG
LED on, when turned on the VS and VA voltages drop quickly and turn off My case was on the power supply board. the cs808 20n j1250v I made the replace and ran for the hug. XANDARE
SAMSUNG UN40F6400AGXZD
Sometimes the backlight turns on and then turns off, giving the impression that it is the LEDs. The defect was in transistor q9801 on the power supply board I just replace it with another one, in my case I put a bc848 and it was great Luiz videotek
SAMSUNG 43F4000
Doesn't work. After checking the "ysus" board, I found the following damaged components: q5000 (rjp63k), c5075 (102x1kv), d 5057(sf 10a400), q5014(fg05536), q5010(5n60) q5021(5n60) Replace damaged components. arock
SAMSUNG UN46FH5003
After changing the main board, putting the 39's of the same model, it worked but it came with the image upside down The solution is to enter service mode, with the TV on standby, using the control press the keys: mute, 1,8,2, power, in a few seconds the service menu will appear, then go to options and then type, just change the configuration to (46a6af0d) then turn off the TV and turn it on again, done.

SAMSUNG PL51D490
Doesn't work I checked the following components; q 5009, q 5002, q 5019, d5010, on ysus, and on zsus q4002. all shorted. After changing them I noticed several bad soldering points on the zsus board. These points probably burned the aforementioned components. Replace the aforementioned components and resolder the z sus and ysus boards. arock
