SAMSUNGUN40F5500AG
Does not accept functions/commands only from the remote control, the TV keyboard works normallyWhen taking voltage measurements on the control board, the IR pin had a voltage oscillating from 1.4v to 1.8v.Defect in ic1201, after taking all measurements of IR line components. The only thing left was the ic1201 as a defect, after changing the ic, the IR voltage stabilized at 3v3 and started accepting commands via the remote control again.EC

Sem backlight, as normalAt first we thought it was a burnt out backlight, but in the end it was working 100%, the defect was caused by a smd 334 (330k) resistor that is positioned right next to the backlight power plug, it is between the cn1401 plug and the fet q1401. the resistor in question was damaged, just change it.Check the resistor in question and replace it if its characteristics have replaced.EC

It works but the back light doesn't come on. replacement of the ICD801, DD850, QD850 on the power supply PCI.Icd801-oz9998bng , dd850-sr210 , qd850 10l01 (mosfet).It worked perfectly after replacing the components described. I used the 15l01 instead of the 10l01 and it worked very well. This TV monitor is using the bn44-00448b or bn98-03094b board.Ferrarini

Turns on, lights up LED bus and turns off, no image, stays in this loopI saw several videos trying to isolate the cause with the famous tape on the flat, that procedure of searching until you find a point that releases the display short and the TV releases the image.I couldn't do it that way, because the short was in the first left flat, that is, looking at the TV lying on the counter with the screen down, the flat that was preventing the TV from working was the first one on the left side. on the left side vcon board tsound is the test point "vgh", the track of this vgh that goes to this flat was cut and the TV worked perfectly without any scratches on the image, to make the cut easier the cut was made close to the r44 on the left side vcon board, please note Tsound you have the vgh point test and the cut I made right after, that is, I will remove this vgh reference that goes to the first left flat...MIGUELTV

Does not turn on or turn on standbyIdentified the following burned components (fuse 5a, qm801cs - stf10nm60nd, icm801 - s3310)I replaced the components above, instead of the (10nm60) I used a kp11n60, instead of the s3310, I used an s3330, taken from another scrap Samsung power supply, everything worked 100% - note; merits also for waterfall electronicsCDS_DIAS / LED TECH
