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	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
