SAMSUNG	CL21CM21MQ	Turns on, works little, closes on the sides and turns off	Cr404s 681k/2kv next to d402	Replace with new	FH solutions
SAMSUNG	MX-F630ZD	Device showing protective message	The aic2 audio output integrated (tas5342a) was removed and the message did not appear, when installing a new integrated the message was displayed again.	All the gaps between the CI pins were scraped as tsound was a lot of carbonization on the plate due to the heating of the part. This scraping was done with the tip of tweezers and assisted by an electron microscope for good visualization. Once that was done, I put the ci back in and the device started working normally again.

SAMSUNG	CL21K40MQ	First it turned on, after two minutes it turned off and didn't turn on again and it didn't even have standby	Cr 409 practically toasted	As I couldn't find the original one of 0.68nf/2kv I put one closer to the original capacitance which was 881k/2kv. it's working perfectly.	Celso
SAMSUNG	LS20CF	Turns off the screen in a few minutes	This problem on this TV is usually in the lamps, a solution without changing them would be to deactivate the protection by removing d1 and d2 on the power supply board		Miratec Eletrônica

SAMSUNG	UN40C5000QM	No image	Main board q202 shorted or charred.	The q202 is a mosfet that feeds the t-com which damages due to something wrong with the t-com, check for shorts on the t-com, the q202 is a 6-pin mosfet, I couldn't find the TV schematic to put an original one with a lot of research I adapted another smd mosfet code: ao3407a with 3 pins that works perfectly before connecting the t-com turn on the TV without the t-com flat being connected and check if it releases the 12v line, if it releases the main board it's fine again, turn on the t-com after checking for shorts in the capacitors, I got 2 TVs with this same burning problem of the q202 and different places on the t-com one of the problems on the t-com after solving the short it still did not release the vgl and vgh which it was another smd mosfet broken with leakage, in the qp1 position it has a 3-pin mosfet and has the symbol of a ci drawn on the board, without a diagram again i used the same mosfet that i had already used in the q202 or ao3407a and then it released again the vgl and vgh voltages, only after that I turned on the display flats, making sure that all the voltages were restored, knowing that if something killed the voltages again it would only be the display itself, but both TVs and displays were good, and they worked perfectly again! I hope to help the group, as I have already been helped with other good tips published sound!	Play Back

SAMSUNG	UN55F6400AG	Turns off via the control and doesn't turn on afterwards ONLY turns on if you unplug it	Power supply defect	Transistor qq852 and resistor 10r smd 100 position rs802	JORGE TVPARANA
SAMSUNG	RT59EBPN	Doesn't work	Relay ry71 is dead, you must change it. and it will work	Observ: main board code: da41-00222a	Kaya Elektronik09
SAMSUNG LED	UN46C8000 UN55C8000	Burnout of the stand by transformer -tb801s - resolved	To solve it, you have to adapt another one in its place, you will find it on the power supply board of a Samsung TV - bn44-00357a - problem solved. I advise using the power supply scheme.	After placing the chopper that they sell as original in ML and that is produced in China, only disappointment, the TV returned twice under warranty with the same defect. Even changing the ci, capacitor d 47x35v, doesn't solve it. The best way was to adapt a chopper from a plate I found in my stock. the chopper code is: efd2525,600μH pd46f1n-stb	Eletrônica ALLFATV
