Re: Samsung UE26D4003BW stand-by light blinking
It's late but if someone still needs a solution then they should know that the led bar is broken and the circuit breaker protection is working. It is difficult to find the led bar for this size 26 ".

Re: Samsung-UN39FH5000FXZA-Will Not Turn ON
I had the same situation and it was short on 3.3V on processor, NAND or both. Disconnect pin 14 (on / off-power) at CNM803 with a needle. IC201 generates this 3.3V voltage . Probably the main source produces an overvoltage and this defect occurs, which I have encountered several times, sometimes associated with the failure of the LED inverter.

LG 42PJ350 warm IGBT
Dear colleagues, I want to fix the LG 42PJ350 that burned the C766 330pf / 1Kv capacitor, and the IGBT Q11 (30J124) and Q21 (30F124) all came in from Y SUS . I have changed the three components from two different sources and the situation is the same. At startup, the image is very bright, with lots of red and noise as if it were a weak signal TV. In 20 seconds, the image gradually returns to its correctness, but the radiator on which the Q11 (30F124) lies is extremely warm . It looks like it's all in the area of this transistor and this in max 30-40 seconds. I do not find anything abnormal in...

Led, lg 42lx6500
Dear Sirs,
I deal with LG 42LX6500-ZD, chassis LD03R that has no back light and sound after an interruption of the power grid. Now understand remote control & buttons in that enters and exits the st.by. LEDs by board operates correctly. I found absolutely nothing wrong. I changed the submicom's EEPROM unsuccessfully . There is no activity on the I2C between subMICOM and MICOM.I guess now that NAND flash is corrupt, but I have not firmware.
Any ideas would be much appreciated.

Re: LE40B530 int. loss of backlight
I searched two days on Google and found dozens of requests for this fault but no resolution. Samsung knows the situation since making an indication.

Re: LE40B530 int. loss of backlight
According to the application note AN-6027 from Fairchild, resistive divider network ratio is 155. We calculate and report must be exactly 390V. But two of the four 1,5Mohm resistances are in reality only 1,385Mohm and 1,456Mohm respectively( measured out of circuit) .
Therefore Vout is a little small even after replacing the IC.
Keep in touch.

Re: LE40B530 int. loss of backlight
Dear Tom66 have you solved the problem? I have the same fault on my tv .
I guess it must be 390v not 344v . Is it somehow related to?
